Do i need to be crimping my .40 S&W rounds? The instructions that came with my lee die set are universal and have a separate section for if your die set has a crimping die. I dont believe my die set has one, it is the 3 die carbide set.
I loaded up 5 rounds of 155 grain xtp's on 10 grains of blue dot. they worked (shot out of my M&P 40) fine but there was really no crimp at all. The wwb's appear to have the case taper in toward the bullet right at the end, is that a crimp or just the way they are made?
How can i tell if my seater die crimps or not? the instructions say something like "turn the die in until it touches the shell holder, then back out three full turns. then screw the seater plug in until the correct COAL is achieved. if you would like a crimp adjust the die in to achieve the desired crimp." does that mean keep screwing the die in until it starts to crimp the shell? wont that change the COAL? or do you adjust both at the same time, die in seater plug out?
