To stock pile a good ammo of non-corrosive ammo.
HAHAHAHa. I'd love that. But for me, it's wishful thinking. AT over $21.00 a box, even the Tula steel case stuff is $$$$. my LGS has Remington brass case- $37 for 20 rounds. I'll save that for shooting matches. I'll practice with surplus.
The only thing nice about non-corro ammo is you don't have to clean right away.
Other than that, corrosive ammo is no big deal. At approx $150 (with shipping) for 880 rounds (2 spam cans in wood crate with can opener), corrosive ammo is a bargain.
Cleaning corrosive is not the chore people make it out to be.
#1. Shoot till hot
#2. Spray chamber, trigger group, bolt, and bore liberally with windex
#3. Rinse with super hot water. Hot water evaporates faster (hence getting the rifle nice and hot helps, as well).
#4. Spray with WD-40 to "displace" any water
#5. Clean with Hoppes #9- specifically states it nuetralizes corrosive salts (it's been around since corrosive ammo was common).
#6. Oil with rem-oil or something similar.
I clean at the range when I'm done shooting. Takes me 15 min tops.
Some of the "old timers" I shoot with tell me stories of how, in the military, they used to take their old wood stock rifles into the showers with them. Super hot water, rinse out the salts and powder, clean, oil, and then white glove inspection.
