I don’t do it scientifically like the guys above. normally, after every three or four firings, I take a cordless drill and find a socket that my case will fit in normally a deep well so the neck and shoulder sticks out only. I’ll count to 10 and hit it with my propane torch and drop it in a bucket of water. I can tell you my neck tension when seating bullets is very little. Almost feels to light of tension when seating to me after annealing o matter how little or a lot of heat us applied after playing with annealing over the decades. Be honest, I like the way, Boolits seat and brand new brass, or within the first three firing before any annealing because they see with a good amount of force. After annealing And shooting and repeating the process I never get as much seating force and it never feels consistent “by feel” I need to get some kind of force measurement on my seating handle,
