I have experience with taper crimp, but not with the lock and load system, I use a rock chucker. However, my general rule of thumb with taper crimp is to run a round up on the press and adjust the crimp die down over the round just using my hand until I can't turn it any more. I have found it to be a feel thing.

Also, if you are using a slower burning powder, you may want a little more crimp. If that's needed, I adjust the die one flat (lock nut RCBS dies) down and test until the velocity straightens out.
