I'm going to attempt a functioning CB load for the M1A. I've read Bruce's thread and this is what I have so far:
1x fired Lake City brass (fired in subject rifle) full length sized in RCBS X Die.
Trimmed to RCBS specs, chamfered/debarred and Primer pockets reamed
Lee 170 RNFP cast from ACCOWW, powder coated, gas checked and sized to 309
CCI Large Rifle primers
A bottle of IMR 4064
From what I found, Bruce never used anything heavier than 150 grains with 4064. Any ideas for a starting load? 25-26 grains? Any risk of SEE with 4064?
