[QUOTE="QuietTexan, post: 2943114, member: 116181"] I stopped measuring on my hunting loads. I FL size without the expander button in and seat the bullet. Somewhere between that tight and whatever the case is if I were to pull a bullet after seating would be the "correct" setting, but since the bullet is one solid piece of metal it acts as it's own expander. Crimping is the same thing - Cup and core bullets you can 100% crush with a Lee FCD, but I've never gotten a die tight enough on a Hammer to cause a problem. Brass in the case seems to displace more after a certain point, but it's not getting any tighter because the bullet doesn't deform. When I do crimp I use the ButterBean method of marking the die to get a good level of consistency, and this is one of few times that I consistently trim brass (full length, not WFT on the shoulder) to keep the crimp die setting consistent.
