...if I do the "contact shellholder plus one-quarter turn" I may get 3 loadings out of the brass. Using a comparator to set the shoulder back .002" and annealing every third loading, 20 loadings are quite possible.
Similar and I would add that whenever I've had a problem with semi autos, bolts (usually.older Mausers) or single shot rifles it's because I didn't size them correctly. I either full length sized them and push the shoulders back too far or neck sized them and had chambering issues.
To fix my issues, I fully prepped the cases (clean, deprimed, size and trimmed) but when I sized them I did a partial full length size. That mostly fixed my issues for all actions except semi automatics. With those, an ammo checker and or comparer tool has kept me honest. Never had a problem after that.
Sierra Bulletsmiths will tell you (cause they are always telling me) all reloading should be done using a PFLS method.
