sorry I wasn't sure where to post this question, since it doesn't really have to do with cast boolits.
I just bought a new M70 in 7mm mauser and its presented a new challenge for me. up until now ive only reloaded strait walled cases and now im faced with bottle necked cases. so my question is: can you get away with only neck sizing bottle neck cases to increase case life?
I figure when you first get the brass you should full length size it. but once its fire formed to your chamber then the shoulder shouldn't change size much after the first shot if you use it in the same chamber. with my 45-70 and .357 i only full length size on the first sizing then after that i only neck size to increase the life of my brass.
im looking at buying these two sets to get started:
