These 357 will be semi hot rounds with 13.5gr if 2400 and with a coated 158gr rnfp bullet.
Manuals differ in OAL. Some have 1.590 and others have 1.550 or 1.570.
Bullet I’m using will need a OAL just of 1.570 in order to crimp at the crimp groove.
Photo below is 1.575 and crimped just shy of the groove. I’m also using the Lee COLLET crimp die. Not a taper crimp or roll crimp. Was suggested to use in rounds that will be used for both a revolver and rifle.
Does that round look good?
Should I let it out to say 1.580 and don’t worry bout the crimp groove?
I can also run it a little shorter but then pressure spikes will likely happens using 2400 powder.
