Hi all
I cast my first batch of projectiles last night, mould used was the RCBS 37-250
for the 375 Winchester, alloy used was wheel weights, the Projectiles finished size was .376 out of the mould.
Tonight I made a dummy round, I fixed a hornady gas check to the bottom of the projectile, I then noticed the gas check had a larger diameter than the Projectile
at .379, is this normal and what effect would this have if I were to fire a bullet with a larger gas check, would it create unsafe pressure?
I beleive the hornady gas checks are supposed to be crimped, maybe that is why they have a .379 diameter.
Regards, Jaeg
