anyone use these bullets (#3037) for M1A reloading? they must be designed for a different cartridge (?30-06), because when seated with the cannelure mostly within the case mouth, COL ends up being around 2.720. Hornady manual says COL should be 2.78, but at 2.78 the cannelure is way outside the case. and of course when seating most bullets without a cannelure for an M1A I would just use 2.80" So how deep should I seat this bullet?
