Yesterday, I loaded up 30 of the .38 bullets I got from MBC. These bullets have a crimping groove. Did some reading up, and it seems like most just load the depth to the groove and don't worry about COL. Crimped them with the Lee FCD....tapered into the groove. I will probably shoot them this weekend, but so far, I really like the idea of the crimping groove.....

Yep, give something for the crimp to hold on to and keep from deforming the bullet. I don't worry none a-tall about COL in a revolver cartridge, as long as they don't stick out the end and bind up the cylinder.

The crimp groove is your friend.

Put 6 of them in a speed loader, emptied the cylinder and loaded...so far so good. Rotated the cylinder, and no binding....think I'm gonna like the groove.....

Hornaday's 180's have two. Pick your poison. They were actually designed that way for a contender in the back groove or a revolver in the forward groove.
