7 full months later, I finally get around to loading them up sending them down range, in my 25Creedmoor...THEY SHOOT WELL! Seated them to 2.170 cbto, -.030 off, just a starting number, to see what it'd do. Did a StaBall6.5 & H4350 test. Didn't finish the last StaBall6.5 string, because of pierced primers. Used the Fed GM205M, becasue used all my ARMatch primers. That cup isn't as strong unfortunately.

I’ve got almost identical data in my 25creed with h4350, finished at 2840fps with good accuracy and excellent ES. Using lapua small primer brass and CCI #41. Also around 0.030” off.

AR primers, are the key, with 25 Creedmoor! I'v been using my FED GM205M's (Ran out of Fed AR Match), about a 1/4 of the primers are pierced, on normal charge weights, in my rifle.
Gonna go back to the BR4, they work.
