Thread: Case neck sizing and effect on accuracy

I have yet to see anything ie data / tests to a reasonable scientific level that proves to my satisfaction that neck sizing is actually more accurate than full sizing. What I do see is the brass lasts a lot longer.

One thing I do think is important is neck tension so annealing the neck every few re-sizes, or any other work that makes the tension more consistent in this area seems to be worth the effort for competition work.

Hunting I think I'd always full resize to guarantee you can chamber a round when dinner turns up in front of you. As while target shooting I've had the odd occasion when I couldnt chamber a round, dinner would be long gone by the time a new round is ready to go.
