Are you over crimping? Too much crimp can cause over pressure.

I thought the primers looked fine too. I've seen some flattened primers and it was way more than those.

Thanks guys. I think I’ll look into an adjustable gas block.

I have adjustable gas on everything. AR's chambered in: 308Win . . 223Rem . . 5.56X45 . . 300BLK . . 6.8SPC . . 6.8SPCII.
If you add adjustable gas,make sure that you can get to the adjustment easily also. Some of the darn things expect you to remove the forearm ass'y.
If a load ejects too far fwd or aft,if the load is too hot or cold,if you feel that your weapons dwell time is adversely effected - - -> adjust in small increments. Keep accurate and detailed notes of the adjustments to each gun (I use the clock system ). You might never have to re-adjust . . . but then again ??
I have found that the basic reasoning for adjustment could be:
* Your load is too hot or too cold.
* Shooting subs
* Unusually heavy bullets for bore size (needs to be very lightly tweaked)
* Gas ports too big or small (YES some come from the factory frigged up)
* Make sure that you check the list of other things that could be outta whack BEFORE too much adjustment frustration. ---- SAWMAN

Nice post Sawman,I have and do mess with buffer and buffer spring first,Buuuuut had a AR in 223 and while shooting reman fed loads 3 boxes(1000 rds each), would shatter buffers, was over it after 3, Adjustable gas block went on it never thought twice of adding to the build/put together bench,some may be wide open but,ya have the option to turn down if needed. Just my experience with 4 Ar platformed rifles,and they can do get to dreamy to shoot if they help,not hard bangs at the buttstock and a bit quieter closer to the shooter as far as action noise.
I'll have to agree, good information. One of my AR throws the cases about 1 and 2 o'clock, didn't know why. I think I have another adjustable block around somewhere to try.
