Was asked that question, and for me this is what I came up with:
For rifles in 224 & 6MM, that I would use for p-dogs and varm, think that 300 cases would be minimum for each rifle I shoot. 500 would be better.
For my Milsurps, all 30 cals, I think 200 would be minimum, 300 better.
For my heavy rifles 375H&H, 444, and 45-70, 100 would be minimum, 150 would be better.
For my auto hand guns 300 minimum, 500 better.
For my revolvers 500 minimum, 750-1000 better.
I am not much of a handgunner, but enjoy shooting them. If I were a match shooter, I am sure that my quantities would increase drastically. However, I am a varmint shooter, a hunter, and a paper shooter. Probably shoot between 3000+ roounds a year. (Down from what I used to shoot when I was much younger.
Will be interested in the responses and comments!
