Hmm. Let's see - I think all my firearms are current or ex-military chamberings:
12ga.
8x57mm Mauser
7x57mm Mauser
.308 Winchester
.30-06
7.62x54R
7.62x39
9mm Parabellum
.22LR - hey, there's one! Oh yeah, I forgot about training rifles...never mind...
That being said, I have the ability to reload .308, .30-06, 7.62x39, and 9mm. However...
My grandfather (who will be 89 on Friday) has decided to cut back on his reloading, and gave me most of his existing setup last week (including a Dillon 550B). Apparently, in theory, I can now also reload for several calibers I have nothing to fire out of, because he had dies for:
.25 ACP (yeah, I can't figure that one out, either)
.32 H&R Magnum
.380
.38 Special
.40 S&W
.41 Magnum
.45 ACP
.223 Remington
.243 Winchester
.30-30
7x57mm Mauser
7mm Remington Magnum
.444 Marlin
I also have about a metric buttload of brass (it was already an Imperial crapload before I got his brass stash), in these and many more calibers.
Guess if the S really did HTF I could load and trade these for other things.
