I've seen threads on other forums where individuals pull bullets, dump powder and put the primed case over a non-galvanized nail, fire the primer with a hammer and punch and then watch the nail for rust. Actually about to try this with a big lot of Chinese 7.62x54 I've purchased (goggles and earmuffs, of course). When shooting corrosive I've found it handy at the range to put a few inches of water in the bottom of a bucket and, with a cleaning rod, pull wet patches up to the chamber a few times with the tip of barrel dipped in the water. Fast and neat.
