I have been reloading 45 acp and 40 sw without any crimp, I will begin reloading 45LC and have heard people talking about crimping, Need i crimp 45 LC? I will be using Lee 3 die set for the LC. Titegroup and will try wolf primers and 255gr cast rnfp bullets. Thanks for the help!!!

Yes, you need to crimp the 45 LC. Most if not all revolver loads require a crimp to keep the bullets from comming forward in the cylinder and jamming the gun. which will require you to take it to a gunsmith to have it fixed.

Most highly recommend crimping revolver cartridges using the superior Redding Profile Crimp die.

So adjusted, it can apply only a gentle symmetrical taper crimp. Or it can apply that gentle taper, AND finish with whatever style of 'roll' you wish, from little up to breaking the tip of the bullet off.

Tested to decrease velocity variation and increase accuracy.

I dont crimp anything except hot loads. I adjust to only take out the flare. Never had a problem in mine except with hot loads with 357 and 44mag.
I reload 38/357, 44spl/44mag, 45auto, 9mm, 380.

I have loaded 9x19, 9x21, 38 Super (family), 38 Special, 357 Magnum, 40 S&W, 400 CorBon, 10mm, 41 AE, 41 Magnum, 44 Special, 44 Magnum, 45 ACP, 45 Colt, and 475 Wildey.

All crimped in some fashion.

Commercially, even
