Re: Headspacing FL Dies?
Yes, but with a different spin.
I believe full length sizing has occured when we size full length properly, i.e, properly bumping the shoulder to fit. It's not when we have jammed every possible thousanth of the case into the size die in a willy-nilly manner. I mean, it's the treatment of the case that matters when FL sizing, not to be determined by the tolerances of a die and shell holder, right?
I rarely "FL" size the "right" way by fully jamming a case into a die. Sometimes that's needed but only sometimes. It's much better to only insert our cases enough to allow them to chamber easily. I think - am certain, actually - the reason so many "experts" say to only FL reload a case five times and toss them to prevent head sperations are over FL resizing by "following the makers directions", creating the effect of excessive headspace and resulting stretching.
Some of my hot loaded 30-06 cases have been loaded as many as ten times. In fourty years have never had a head seperation nor any indications of one. My cases die by neck splits and an occasional annealing stops most of that. If I had not sized my cases correctly, to fit my chamber, rather than "right", they would not have last nearly so long.
