224 Valkyrie Bolt Gun Reloading and Ammunition / Re: Brass
« Last post by aziroc on July 20, 2019, 08:32:45 PM »
Most of my brass has been Hornady.  Through my gas gun, I got around 4 reloads before the priner pockets were shot. 

I just got 250 federal that I'm going to try out as well as 250 starline.

224 Valkyrie Troubleshooting / Re: The Big Bang Theory

This sounds like case head separation, which is typically somewhat violent. 

A weak point on the brass gives way when the cartridge is fired, typically toward the base causing the fired cartridge to give way when fired.  It’s way worse than a ‘split case’, as the separation happens upon firing.  I have been on the line 2x when this has happened, once an AR15 .223 and the other an M1A .308. 

if the magazine came apart and the rounds went flying, at least they didn’t also detonate. 

One of the things M1A reloads contend with is MG fired brass, which I think unfairly gets a bad rap and overused brass.  Some of the old timers pitch their cases at 5x firings.  others continue until they detect a brass flaw, inspecting cases with a bent paperclip.  I think some of these loads that have been developed for the .224 with compressed powders are harder on the brass than many care to admit.  I’m up to my 4th firing on some of my brass and 3x firings on most of it.  I lost about 15 cases due to split necks in the last range trip due to an incorrect die setting that I did’t catch.   My bad, but I also noticed I lost a couple cases due to blown out primers... oops.  These were book data loads and all under max loads because nothing I’ve loaded has been consistent at or near max - pp 2000 did give some sporadic good groups right up top with 88ELD but would back it up with a 2 MOA group

This can happen to any reloader.  If you full length resize just a little too aggressively, or push the shoulder back just a little too much, load just a little too hot or a combination. 

We’re not loading for machine guns here... presumably ...  NOT that there’s anything WRONG with a .224v full auto, but my point here is that if we’re in this for precision, we have to focus on where the tight groups are and ignore the somewhat dubious promise of the 224 “supersonic to 1300 yards” hype.  Get it to produce the groups we want - it’s still over what a 5.56 service rifle is doing.

Since we've all moved on from the freebore topic, choose a more recent thread to pick apart.

Welcome to the forum. Try some RE-15 with those TSX's . I used Sierra's data for their 77 grainers.

224 Valkyrie Range Reports / Re: Always a Flier
« Last post by JLB-MT on July 20, 2019, 10:35:26 AM »
Another round of the same.   Loaded up some Hornady 75's, 80's and 88's.   Used what little I had left of H4895 on the 80's and tried CFE with the the rest.   The 75's had a .65 group of four and the one outlier for a total of 1.2.  Same with the 80's, four tight and then one way outside the group.  The 88's were all over the place so I am not sure what is going on with them.   Tried differing charge rates for the 88's and nothing but patterns.   My records show that 88's and RL 15 or IMR 4064 are good friends in my gun.  I will go back to that combination again.

Good Morning from Southern Indiana, I am new to the .224, am retired Army and have a M1A in 7.62x51, 2 Savage 6.5 creedmmoors and my MSR now has two uppers, haven't shot the 5.56 in over a year since I added the .224. Shot the .224 at 500 yards last month and did well on an FClass Target.

AR15 Performance / Re: Barrels possible later in the year
« Last post by Constructor on July 15, 2019, 06:23:30 PM »
The 20" 7.7 twist barrels arrived a few weeks ago.  These are more for guys that hunt and don't want to swing a 24" barrel around.     https://www.ar15performance.com/inc/sdetail/38016/60677
