Today I headed off to the range with my Remington 700, Ar-15, and A-O 1911-A1. The purpose (outside of the obvious fun) was to verify ammo functionally and try some new things out. The 700 ate a diet of Handloaded .308 (175Gr SMK over 41.3gr Re-15) with great results:

Also had those little clay holders and was busting 4" clays at 150yrds with no issue.:D

Second came the AR-15 and try 100 rounds of MFS .223. functioned good except for a few issues (not ammo fault) accurate enough for plinking. The issues: The "Dum Dum" who installed the fire control group (ME) put the hammer spring in backwards. So, a few fail to fires and then a big "uh-oh" the trigger pin walked out and when I went to reset my trigger I went full-auto, 5 rounds before I knew what happend. Pulled that lower apart so fast (thanks to my new leatherman M.U.T.) inspected it and realized my error. This is the 5 AR I've assembled and I made a Noob mistake. :(
Now a question for you handload experts out there. I tried some .223 handloads today and something was fishy. I loaded 75gr Hornady HPBT over 21gr of IMR-4895 (actually below the lee data by .2gr IIRC) and the rounds were slamming the BCG hard into the back of the buffer tube. the primers were flattened as well. What could cause that? Shot 4 rounds and called it quits:confused: Acting like a hot load with minimum powder
Finally the A-O 1911-a1 came out to play. I had poor results from my previous trip with handloads and went back to the drawing board. I was running 230gr LRN over 4.2gr Win231 OAL 2.270 and the rounds were FTL and the nose was getting mared up. So I set the bullets down to 2.200 and they worked flawlessly even tried to 230gr Hordnady FMJ over the same charge with 100% success. I just need to get the front sight re-staked and it'll ready to rock and roll.:D
Thank for reading and anyone with advice on the .223 handload I'm all ears.:o

Was the brass for the .223 trimmed to length? Overly long brass can cause the bullet to get crimped during chambering which can cause pressure spikes. Are you using military brass? Military brass is typically a little thicker than standard factory brass, which reduces the internal volume of the case. Minimum load for factory brass will run slightly hotter in military brass due to this.

I made sure that all cases were trimmed to spec and using only .223 brass mostly Federal with some Remingron and PMC mixed in. I'm not crimping them (no cannelures). This baffles me all my reloads have been fine (spec pressure) until these.

I've had that happen with a 22, it definitely gets your attention huh? Woops!

Glad you got it figured out.
