I did my Missouri 124gr at 1.095 and I'm about to try some ibc 125gr at 1.125. I believe ibc and mbc use the same molds.Shot the IBC Bullets this weekend and they shoot great! Barely any leading! Will definately be buying more from them! The bullets I am using are the 124 gr 9mm. My book says to seat them at an OAL of 1.115! I did so and they wont chamber in my EAA Witness 9mm. What does everyone else seat theirs at? When I load 115gr FMJ's, I seat them at 1.090. Any help would be great!
