I have some 45acp loads, with Ranier 230gr JHP bullets that I have loaded with 10grn of No.7. I loaded them at the books minium OAL of .1245. They load perfectly in my G36 mags, but will not load in my SIG mags. I have to bring them down to about .1225 to fit the SIG mags. How do I know if I am compressing the loads? 10 grn's of No.7 is a minium charge. It shows no signs of to much pressure at .1245, is it safe to seat the bullet to .1225 to cycle in my Sig.
