I am new to this forum. Just started reloading and bought a Classic Lee Hand Loader in 45-70. I also bought a Lee Hand Press for 38-55 later, as they didn't have the Classic Hand Loader in 38-55. Haven't started loading 38-55, but have the 45-70. I am having a terrible time seating the bullets in the 45-70. Last night I hand loaded 15 rounds, and in the process ruined 7 cases. When I would try to seat the bullet (a 250 gr. Barnes X bullet), it would bend the sides of the casing. I have lubed, but is no apparent benefit. My 38-55 cast bullets should be in this next week, which are .379 in diameter. I know I have read on this forum previously wherein others were reloading the 45-70 and .379 diameter 38-55's. Is anyone else having this problem? Can someone tell me what I need to do to solve the problem? Incidentally, I am using new unfired cases, and my 45-70 is the H&R Buffalo Classic and the 38-55 is the sister Target Model. Thanks,
