Yes I am aware of that. I bought a case (2 spam cans) years ago when I bought my 91/30 and still have quite a bit left. I usually run some wipes through it, then follow with a heavy ammonia Windex bath down the barrel and a good soaking of the bolt while it's out as well. Is this correct procedure? Seems to work good so far.I trust you are aware of the probable corrosive nature of surplus ammo & know how to clean accordingly?
I think I'll start reloading to 30/30 velocities one of these days just to make it a more enjoyable experience. Plus I won't have to worry about the corrosive primers that way either.
