I've started loading some 40S&W and I'm concerned I was over taper crimping.
So tonight, using a set of three Redding dies on a LNL, I seated a Montana Gold 180JHP to 1.125, and then started backing out the taper crimp until it would no longer pass the Plunk test into my barrel.
To my surprise, I was able to entirely remove the taper crimp die and still pass the test. The seating die must be doing some crimping, but is it enough?
It looks like all of the bell is removed, except for maybe a tiny bit at the end, but at this point, does it matter?
For the record, I put the bullet against the bench and pushed on the back of the case as hard as I could and didn't budge the bullet.
Should I even bother with the taper crimp die??
