Since I started loading for .357 mag. I have always had issues getting a decent crimp that is tight enough to prevent bullet jumping. I load full magnum stuff all the time, but never did the right thing and bought a roll crimp die to solve my occasional problem. Today I decided to try belling the mouths to see if it would change the characteristic of the taper crimp. To my surprise, it worked quite well. The crimp had more of a 90 degree position into the canelure which produced a much better position into the canelure. I'm guessing that because belling produced a little more brass due to the stretching, it gave me more to work with. It allowed the mouth to fold in to the canelure with a better angle.
Even after all these years we can still learn something new that works better for us, if we are willing to let the old dog learn new tricks!
