Crimping Handgun Rounds In Light Recoil Calibers

Postby hillbillybear » Mon Jun 29, 2015 5:00 pm

Is it an absolute necessity to crimp handgun ammo for use in revolvers in calibers with light recoil (i.e .32 H&R) provided that good neck tension and proper cartridge OAL are maintained?

I don't think it's necessary.

if it helps anything it would help a consistent burn of the powder from a crimped round, that may or may not help accuracy.

You would just have to try it.
Sometimes you have to ignore the "good idea fairy"

Please stop telling me "That can't be done" while I'm doing it, it's just plain annoying.

I loaded up a couple of cylinders full of uncrimped rounds for a .32 h&R magnum and they functioned and shot pretty well.

Some slower powders such as H110 and 296 require a heavy bullet pull for good ignition. Otherwise the primer blast may start the bullet moving before the powder ignites and the reduced loading density caused by the initial bullet movement causes a lag in ignition. Blue Dot is also prone to this behavior.

With faster burning and easily ignited powders, crimp is unnecessary, except in heavy revolver liads subject to inertial dislodgement of the bullet.
