Proper use of old style hand crimpers

For an insulated one
Dan guys, I have the same crimpers as the orig. post, have used them rewiring the whole car, and everything else I`ve had to do wiring on. I always crimp the ins. ones to the point of cutting the ins., and then slide some heat shrink over it , 'IF" I can rember to put it on, haven`t had any problems w/ any connectors installed in any position. I always pull on them pretty hard to make sure thei good to go. Been doing it that way for 45years?
I think u guys are overthinking the whole process !
