Pm sent......

Initial testing indicates that this bullet is mostly useless for auto loaders - I may revise the design and try again at a later date.

These may make great single-shot bullets though, so I am certainly going to save the remaining ones for a time when I have a bolt gun in this caliber.

I don't actually own a FiveseveN yet.

All I personally have is a 16" AR57 - but I have access to:

FiveseveN

AR57 SBR 6"

PS90

PS90 SBR


EDIT - Bullet length is .590 assembled.

So far it looks like my best bet is going to be Alliant Bullseye again. What would you like me to PM you about?

Oh yeah, forgot to mention - the weight of the projo and sabot is 18 grains.

Can you do me a favor by posting the text you used to make that happen in "" so I can see it?

Thanks BTW!

Finally had a live-tool lathe open up and got the sabots made.......going to shoot them this Sunday - QL says I can go up to 3800fps before pressure gets out of norm. http://lh4.ggpht.com/__tjNUnhQGjs/S5qhwGZBUdI/AAAAAAAAAJ0/Hq7IB0AnBGE/s800/Unique%20.22%20008.jpg http://lh5.ggpht.com/__tjNUnhQGjs/S...

"i dont know about you, but the gangsters/thugs dont keep theirs unloaded, what makes them think i'd have time to load mine up, rack it, then go."

I was home schooled from 6th-through grad, I graduated a year early and had a part time/full time job as an aircraft mechanic from age 15 through the end of college.

They arm up because violence is the only thing the state knows how to do well.

I guess the main thing is the fact that the school system has no money of it's own. It does not have to operate like a legitimate business and attract customers based on price and quality. Instead, they just say "pay up" or we'll steal your house, resist and we will put you in a cage or kill you. An...

Red loctite is only on the barrel to receiver interface. All I did was find an allen wrench that would fit between the slots in the end of the flash hider and used it like a "T" wrench. Came off without a fight.

I don't like the AR57 flash hider, gave it to a friend and use a regular A2 hider now.

^^^^

I know, I was making light of the fact that the "education" system needs guns at all. What are they doing so wrong that they feel they need weapons that they restrict for us peasants?

"Why the rub? We are talking about a few shotguns with 14" barrels. What am I missing?"

Guess it's the principal of people calling themselves government stealing money to buy restricted weapons for teachers.

The only thing that comes to mind is this:

The bulk of public "education" (if that term even applies to what they do) is paid for by property tax. If you don't pay it, they steal your house.......if you resist, they send men with guns.

Maybe they are expecting more resistance/non compliance?

I wouldn't be surprised if they at least attempt to ban the FiveseveN......dunno if they can pull it off. And MAKE NO MISTAKE - we have gotten just as many and just as insidious firearm and firearm related bans/restrictions from "good republican" presidents/politicians as from the left side of thing...

According to Quickload - titegroup is borderline useful - not something I personally am interested in.

I'd say pass on that one.

"Letting your county know how many people live there can help PROPERTY THEFT for city projects"

There, fixed it for you.

If I get a census package it will go strait to the paper shredder where it belongs.

I have NOTHING to gain from the state having any more info about me.

Meh, the SCOTUS is just a bunch of grown men and women wearing dresses deciding how the state is going to fvck you in the ass.

"Here in Free America"

If you think America is free, I've got some top-notch ocean front property in Nebraska I'd like to talk to you about......


Back on topic - how do you like the FS2000? Hadn't had a chance to shoot it yet - I did get my hands on the RFB and so far I like it.

Just curious - what state are you waiting on? Here in Tx, you just go buy the damned thing and go home......

^^^^
The M1 Garand needs a cartridge that is loaded to provide a specific pressure/pressure curve - any old 30-06 will work........for a while. Much of the commercial stuff is way too hard on the op rod.

According to Quickload, there is no suitable combination of this powder and bullet for this cartridge that is even remotely close to worthwhile.........

You'll find that you need more of a pistol/shotgun flavor of propellant for this one.

I bought my Gemtech for $250 - they retail for $300, but some guy bought it - fired ten rounds through it at the dealer's location - then gave it back and told them he'd be back in a week to do paperwork. He got fired within that week and sold it back to the dealer for less than he paid for it. Then...

^^^

Good call - yes, I meant for single stage work.

Loading the PS90 mags is super easy once you figure it out. Just like described above - I can load a mag in no time......

Unless you run across some specialized holder for a specific device or an antique - all the modern shell holders are the same.

Yes, you can use LEE with RCBS with Hornady with Lyman presses.

That's a fine looking weapon you have there - congrats!

I'd be a little hesitant about putting it on a shorter barrel with fullspeed ammo. Even with a long barrel, I don't plan on making it a habit to shoot supersonic through this can - just wanted to prove it's possible. Now with subs, as long as they stabilize - I'll shoot them through this an all day ...

Buddy of mine has a BM59 - it's always breaking op rods.......it sure is cool when it runs though......

Yeah, M1 Garand is available in .308 nowadays, another buddy is in the middle of putting one together. It's like a M1A without the hassle of detachable magazines......

Your welcome to use any data I have - at your own risk of course.

What gun are you running? (AR57, PS90, FSN, other?)

^^^^
Haha, you say that - I live in Central TX and it has snowed FOUR TIMES here this year. This is a place where it's exciting if it even snows once for a few minutes.

Sweet! Love the M44, bought mine for $40 a number of years ago......

What is all the white stuff though?

Don - we may need to put our heads together, I design and machine all my own rifle bullets. If you have access to real testing equipment........I can see some seriously cool "open-source"* load development going on here....... *not that there is anything at all wrong with proprietary info, but I am ...

Oooooookaaaaaay........ That certainly is you choice to make and I don't begrudge you for making it. Moving on - is there anyone else here who would like to have an open, rational discussion regarding the effects of different pressure curves on the safety of this cartridge? I both find it fascinatin...

*Disclaimer* - I am using Quickload, which is a mathematical simulation - NOT real world, I am very aware of this...... Ok, now that that's out of the way - according to QL, the curves are damned near the same - if they were very different, even a computer simulation would show some sort of discrepa...

Please elaborate.

Ramshot True Blue has an almost identical curve.......

5.0 grains gives you 61.6% case fill, 33884 psi, and 2131 fps 6.0 grains gives you 73.9% case full, 49195 psi and 2453 fps This is based on a Hornady 40g v-max and a 16" barrel. EDIT - pressure curve is nice and gentle. Also, QL (at least for this cartridge) overestimates velocity, you can expect 10...

Plugged some numbers into QL, and with a Hornady 40g V-max - it looks like this powder has potential.

Maybe I'll see if I can snag some and try it out.

Just ordered 4k, will probably order more real soon.

"Even if I correctly enlarged the hole fourty thousandths, it would still need heat treatment that I can't do."

Re-heat treating it for after that operation would be pointless.

Yup, and with the 40grain ballistic tip and 5 grains of BE - I am getting a full 100FPS faster than SS197.........at literally a fraction of the cost!

Been 100% pleased with mine so far, havn't shot my 5.56 guns since getting the AR57 built up. Looks like I am going to be picking up a second upper from a local guy, gonna chop it down to 6 or 8 inches and run it on a spare Rock River pistol lower I have on the shelf. Then maybe one day I'll get a l...

I developed some loads with a powder that no one had bothered to try - Bullseye - works great for me. QL was INVALUABLE to this effort!

Yeah, most of the sound is the "sproing" of the return spring and the mechanical "clink" of the bolt going into battery. I am toying with the idea of milling some small round shallow pockets in the face of the bolt and pressing in some delrin bumpers that stick out a few thousands to get rid of the ...

Thanks! Worked out better than I had imagined. Not sure if it would be a good idea with a really short barrel, with the powder that I am using, I am getting a 100% burn well before the projo leaves the muzzle. With a short barrel, the blast baffle may take too much of a beating. Course, with subs - ...

Ok, so I went ahead and tried it with full-power and subsonic loads. Worked flawlessly, no damage to the can - very quiet. First video is supersonic hand loads, 40 grain Hornady ballistic tip over 5 grains of Bullseye running at 2200fps. First round did not cycle, gun was dry and dirty - after I cle...

I am using the following loads with my AR15 16" bbl:

55 grain M-196 tracer - 3.5 grains

No pressure signs, cycles flawlessly, lights 90+% of the time even in cold weather.



40 grain Sierra and Nosler ballistic tip - 5.0 grains

No pressure signs, cycles flawlessly, perfectly good accuracy.

Went through a similar process with a Hornady shell holder and trimmer. I am a machinist, so I modified the holder myself - but then ran into the problems of it not supporting the case head well enough for resizing. I just bought a second holder, so I have one for trimming and one for everything els...

viewtopic.php?f=19&t=2646" onclick="window.open(this.href);return false;

There IS a lacquer coating on them. You can get 3-5 reloads on them before they start breaking down. Some have reported good results without the coating - personally have not tried it yet.

There is a whole thread on replacing the coating, with various degrees of success.

Just ordered one of those AFG, planning on attaching it to my AR-10 to make shooting that heavy beast off-hand a little easier.

Strait blow-back on the PS90 and AR57. Delayed blow-back on the FiveseveN. EDIT - kinda like the HK MP-5/G3, no gas system so the use of lead bullets is fine so long as you come up with a good load that doesn't lead up the barrel. I'd like to know how it works out as I use A LOT of cast lead bullets...

Buddy has a set - they seem to work fine - we both have used them a bit. Just curious - are you using them with a LEE Classic press? I have noticed that this press restricts seating depths quite a bit. I use it just for depriming/sizing due to the ultra-cool spent primer tube - and use my rockchucke...

Outstanding! Thanks for posting!

On the few cases I have CNC turned from barstock (7.62 X 39 and .50 Beo), I have drilled out the inside undersized and then bored out the remainder. This allows me to generate the proper wall thickness and webbing taper, I'd be a little apprehensive of using a cartridge case with no webbing even in ...

Thanks for the info - I really didn't mean to say anything BAD about EA - they have spent time and money to develop some killer loads. And regardless of whether they do use a secret powder or not - I have nothing against it, just too expensive for me to go play with. Personally, I'm not interested i...

Also wanted to echo Grantness on the cost savings/performance benefits - 5.7 X 28, despite being an "exotic" or "wildcat" - it is the least expensive high-velocity cartridge I load..........and I load a LOT of calibers. So, you can certainly save some money and on top of that, make the civvy FN stuf...

+1 on what Grantness said. I have been reloading for some time and AND have a software package called "Quickload" that calculates internal ballistics. This software can only tell me what it "thinks" it's going to do, so careful development is still VERY MUCH REQUIRED. Personally, I have a 16" AR57 d...

I make my own banded solids on the CNC lathe - and yes, they are longer for a given weight because of the material density. I use C360 brass, and my 58 grain .224 bullet is .930 long - the smaller the diameter, the longer for a given weight they will be compared to a lead-core bullet.

I have suspicions that EA does NOT use a "secret" powder, but that's neither here nor there - they do make awesome ammo, just not a price point where I can afford to shoot more than 100 rounds...... Personally, I have been exploring powders that no one else has tried and bullets that I make myself o...

Oh yeah, saw that one - but that's not what I was talking about......

I want to use an AR57 barrel to build a lightweight bolt-action that feeds from FiveseveN mags.

I don't mean to brag - but I never have this problem. I always back out my seating die a few turns and work it in a bit at a time.

Havn't ruined one yet.....

Thanks for posting the info - I'm glad to see someone trying Bullseye in the FSN - been working great for me in the AR57.

If someone would post a link to that site/thread - that would be awesome! I would love to see how he/she is doing it and if they are using an existing action or not.....

I've been having the urge to order a spare 16" AR57 barrel and use it to build a bolt gun using an existing action - or just making my own........either way, I think it would be cool to have a lightweight bolt gun in this caliber that feeds from a FiveseveN mag.....

Not picking on you, but it's "barrel"......not "barrell".


And yes, I would like to help by providing whatever data I develop. Most of my stuff is weird or exotic loads, but I will gladly share it if it's wanted.

r1abuser - nice setup, PM me if you want to work together on some subsonic stuff - got some stuff that is working, and more ideas in progress.

Guess, I'll throw a teaser out there................. Working on a .172 bullet inside a discarding sabot for the 5.7 - according to QL, I should be able to get very near 4000fps with an 18 grain combined projo weight with Bullseye powder before I exceed pressure limitations. I have already made the ...

I turned some .308 bullets out of Delrin on the CNC lathe, loaded them up with 3 grains of Bullseye, and shot them out of my Ishapore "jungle carbine" Enfield copy. They didn't stabilize past 10 feet, but they were quiet and could be stopped by a VERY minimal backstop, I.E. they would work as a "bas...

"Great info and very interesting bullets (solid brass)!" Yup, turned them out of C360 brass on the CNC lathe, every 15 seconds a bullet will drop off! "what type of fins design were you thinking" We'll have to see how it turns out, but what I have in my head is a teardrop shape up front, then a shor...

Oh, also - if you listen carefully on the last round - you can hear a "double bounce". Since the bolt is closing on an empty chamber, there is no drag and you can hear it slam home, bounce off the chamber face, and then close again. When I was shooting it, I could clearly feel it happen........

Ace makes good stuff, have their original skeleton stock on my AR-10, love it!

Esteves - all good points, I was pleasantly surprised as well......more development to come......

.930 I am planning on making a subsonic-specific one as soon as a machine frees up at work. Going to make it a blunt and "teardrop" shaped as possible and still have it feed - as this shape is the most efficient at subsonic velocities. Also plan on putting a finned tail on it so it will stabilize re...

Thanks! Can belongs to the guy that was holding the camera, need to figure out which one I am going to buy next as the only one I currently own is a Gemtech Outback....... I just got my new stock in the mail, bought an ACE Ultralightweight Entry - the lightest one they make. It has a short pull leng...

So I have been making and loading this 58 grain mono-metallic lathe-turned bullet for almost two years now. Been using it in my bulk .223 loads with 22 grains of H322, it's very accurate, clean, consistent load. I decided to try it in the 5.7 as a sub-load. Started out with 2.0 grains of Clays, this...

Lemme guess, some jackass p-shopped it.........
:wall: :wall: :wall:

Well I'll be damned!

Whatever happened to that project?

I would love to have a couple rounds of that just for samples to put on the shelf.....

I don't know, but no one in the us that I know of makes steel cased ammo........

I wish Wolf would convince one of their suppliers to start making the stuff!

I honestly don't know - that was the only thing I could think of........

Maybe they are afraid of the start-up costs to do the coating.

From what I understand, it has to do with legal issues - FN has to authorize it, I guess until whatever patent runs out...... I may try making some myself on the CNC lathe when a machine frees up, made some .50 Beowulf last year that worked pretty good. I can't sell it though or the F-troop will kic...

Ok, got some more data to share! These tests were performed mixed brass, Federal SR primers, Alliant Bullseye powder, Chrony Alpha chrono, and an AR57 with a 16" barrel. Oh yeah, bullets were 40 Nosler ballistic tip boat tailed. Outside air temp was about 65 degrees. 4.6 grains 2102 2133 2101 2073 2...

Personally, I am getting rid of all my RCBS dies - they are JUNK. Had a set of .40SW carbide dies I bought brand new and they destroyed about 1/3 of all the cases you would put through it. Same goes for a set of .308 dies. Garbage in my opinion. I now only buy: Lee Redding Hornady CH4D Personally, I...

^^^^

Yup, I have the custom-grade Hornady 5.7 dies and they are the cat's meow - I am VERY pleased with them.

I have a slightly older version (3.2 IIRC) and the 5.7 is in there for sure.

QL does predict muzzle velocity, so far I have only chrono'd 5.7 out of my 16" bbl AR57 and real-world velocities tend to be at least 100 FPS slower than predicted.

Ok, I need to post up some pics and some more details - but so far I am very happy with my Primary Arms T1 clone. Got to shoot it today and it performed flawlessly, going to order a few more for other weapons......

Here's a video from today, all the tracers with this load seem to light - but I was shooting at a plate @ 80 yards - so not all of them had time to light up.

http://www.youtube.com/watch?v=xEwcNN5a8sw" onclick="window.open(this.href);return false;

Yeah, QL is predicting 53,431 psi - I wouldn't go there.

YES!!!

Someone else using Bullseye!

I fired 58 tracers out of my AR57 with 3.5g of Bullseye today. I have some data to post up on my Bullseye thread - I took 40g V-maxes all the way up to 5.0 grains and all was well, getting slightly more than 2200 FPS...........with a FORTY GRAIN bullet.

F-n A!

Glad it works!

I plan on keeping my damaged coating brass for use in a future bolt-gun build or for experimentation/dummy rounds.

And yes, I am having a helluva good time playing with load development for this cartridge!

Has anyone tried dry graphite?

Your supposed to use a little bit now and again with the Beta-C mag, I have one of these mags and a couple tubes of the stuff.

Guess when I get a pile of "questionable" brass, I'll load it up and test it out. I have an AR57 and access to a PS90.

I just received my Primary Arms Micro T1 clone, paid $60.

So far it's slick, very compact and very lightweight. I will be shooting it Sunday, so full review after that.

I use 3.5 grains of Bullseye under the 55g military pulldown tracers. It lights every time even in colder weather (EA - eat your heart out! :p ) There are no pressure signs and I am planning on working up a bit, but out of my AR57 with a 16" barrel - they cycle and light every time. I have no idea h...

Good point Esteves - we were using a Bowers 9mm can - so I guess you could say we were "cheating" by having a little wiggle room in the baffle center holes.....

Just remember - the data above is for a SIX INCH BARREL - the same 2.7 + 55g bullet stuck in the PS-90 with a ~14 inch barrel.

YMMV

I am still developing subsonic data, but 2.7g of Hodgdon Clays (NOT International Clays, just plain Clays) under a 55g bullet works well out of a 6" barrel. 2.5g of clays and a 62g SS109 also works out of the 6" barrel and stabilizes to at least 20 yards - more than enough to get it safely out of th...

I have seen it done with subsonic ammo. Don't know what to tell you about the fullspeed stuff....

Thanks for the info!

I am a CNC machinist, and we make parts that size - let me know if you want to get in touch with a shop that can actually hold tolerances......

Hey Panzer - I bought a set of dies/EA Dillion 550 plate/brass on afrcom EE a while back. I do not have a Dillon, so I sold it to a friend of mine who does have the D550. The EA conversion plate I got has the early aluminum buttons. Is this a problem? Will you sell the brass buttons by themselves? W...

^^^^

I think that was a problem with the earlier uppers from what I have read. Both myself and a friend have purchased recent production AR57 uppers and our shoulder movements are no more than with the PS90.
