Most of what I shoot is pretty common calibers (9mm, .380, .45acp, .38sp/.357 mag, .223/5/56, 12ga, 20ga) and I've got around 1000 rounds for each of those, except the 9mm where I have closer to 2000 rounds. I figure that's enough to last me 1 year on everything. Oh, and probably only 100 rounds of .270, and 300 .44 mag, but I can't remember the last time I even shot either of those guns. I also have components to reload between 1000-2000 for 9mm, .38, and .223, and will work on building up .45 bullets (I've got the brass). I also have roughly 20k rounds of .22 lr., I learned my lesson on that round 10 years ago when I was down to my last brick.
