I generally use the 100 round .50 caliber (840 round 5.56) cans. I bought one from the surplus store last week for $20 that was in good shape, good seals, paint, and no rust. All of the others were of lesser quality but had the same price tag on them. there was a pallet of them in a big name sporting goods store for $24.99 ea.
A whole bunch of; 9mm, 45 auto, 357 mag, 44 mag, 5.56 NATO, 30-06.
I know I need 10 cans because I have basically doubled the amount of ammunition from what I had stored in every caliber.
Hmm, good idea. I found auctions for 12 cans with free shipping. Thanks
