tons and tons of .22 lr followed by much smaller quantities of .38 and .357. My ratio of .22 to the other calibers is at least 6 or 7 to 1. I'd prefer it be about 2 to 1 but, at the moment, I'm scrambling to find .38 and .357 ammo just like everyone else.
Usually .45 but last few months 7.62x25. This ugly-a$$ CZ-52 is is fun as heck and this caliber at least out of this pistol, tears stuff up. Shame there aren't any modern pistols using this caliber. Not that it matters anyway, being in CA, probably wouldn't be on the "List" anyway.
No offense to anyone here that loves the 9MM but I have shot the M9 and M16 for 15 yrs in the Army and I ache for the Army to go back to the .45 or a .40
I shoot .40cal (in my XD 40) or 308 (in my M1A) can't stand the M4 either.
.357,.38,9mm,45ACP,44 Mag,45 Colt-I mix 'em up on trips to the range for variety.
I have .327 Mag,and 7.62 Tokarev,22LR,and 22 Mag also,but I shoot them less frequently.
One strange thing I've found is that when I shoot 44 Special from my 29 and then 44 Mag,I always shoot MUCH better with the Mags
22 LR, 17 HM2, 22 Mag, 223, 357 Mag. 22s in my scoped Single Six are cheap and they keep me sharp for deer season with my scoped Security Six, my 10/22s and my 17/22 are fun for tree rats, woodchucks, and snowshoes and my Mini for coyotes.
