30cal or 50cal? My 30cal can from BSA days in the 50s & 60s was badly rusted, and it took me 2+ days to restore it. I keep small bills cash in it, in the massive Cannon gunsafe.
Do you have a link for the new cans? Are they sold in quantity?
These were 50 cal from ammo to go. I checked last night and they’re out. But I found these:

These look like the same deal, but for me the shipping would be kind of high.
Lot’s of unused cans out there right now. The rubber seals on these are perfect.
