Hey fellas. Can you help me out with a seating issue?
It drops from a Lee mould at .452" at 220 grains. I note that the Lyman manual calls for an OAL of 1.272". I cannot get these to cycle through my Springfield Trophy match at that length; the gun will not go into battery. I found that if I seat the bullet deeper, and apply a heavy crimp, the gun will pass the 'plunk test' if the OAL is down around 1.212". Is that too deep? will that cause dangerous pressure spikes? I have only loaded dummy rounds as I try to get this boolit to work.
Am I having a senior's moment? As far as I know, that boolit is right in the ball park and should easily load to book specs. Am I doing something wrong? any help is appreciated, this is driving me crazy....
