My ammo is in a couple of those smaller safes that Harbour Freight has on sale for $80 every now and again. They are perfect and I generally stock at peak:
1,000 .45 ACP hardball
1,000 9mm hardball
200 9mm Premium Hydra Shock Law Enforcement/Self Defense
200 .45 .........................same.......................
250 .45 Long Colt
2,000 .22LR various types, mostly copper washed
2,000 .38 HBWC target loads
250 .357 Magnum
200 .38 Colt (.38 special/.38 super?)
200 .38 +P+ Gold Dots
Think that's about it. Fills two safes to the brim. When I get down to the point where I am having to go find rounds at crazy retail prices I get together with another shooter or two and place a bulk order with Wolf in Kingston. His product is top notch and I have no problems with it in any of my guns. There are some calibres and types he does not carry of course, but mostly he is good.
I have a complete Dillon RL1050 setup here; thinking about getting into reloading and am being bugged about it all the time, but I just don't have the time or inclination to do it right now. Maybe when I have more time on my hands. Anyone interested in a complete Dillon RL1050 setup with loads of dies and all the bells and whistles might want to contact me as I am getting ready to unload it.
