Probably five or six hundred rounds of .308, between surplus and commercial.
1400 or so of 7.62x54R.
2000 of .30-06 on garand clips, and another 80 or so in commercial boxes.
It's hard to keep track, especially if you buy off the shelf instead of in bulk. Probably 500 or so .223 bargain boxes that I've put on slightly rusty stripper clips, and another 100 in boxes. 8x57, 8x57JRS, 6.5x55, 7mm Mauser, .40-82 WCF, .405 Win, .32-20, and .38-40, probably fifty or so rounds of each. Maybe 40 rounds of .300 Savage. Handgun ammo, I've no idea. I know I'm low on .38 long Colt and .38 S&W. .50 AE, one box of the speer lawmans. .41 mag, one case commercial reloads, various boxes good stuff, call it 1,200 rounds. A few hundred rounds of .45 ACP, less 9mm, less still .40 S&W... 200 or so 9x18's, maybe 200 .38/.357's, 50 .44-40's...
Good lord, I have too many calibers to feed.
