Don't let corrosive put you off. Simply clean appropriately. I use black powder cleaner first, then follow with Hoppe's as usual. Don't forget to clean the bolt! You can either use commercial products like TC no. 13, or any other brand, or simply pick up a bottle of Windex all surface cleaner with vinnegar. At the range, I turn the rifle over so that I don't flood the magazine, point muzzle down, spray liberally, then pull a bore snake through. Follow with your favorite oil, and a second, dry bore snake. Wipe down the bolt with windex, dry, then oil. This holds me until I can get a thorough cleaning at home. The corrosiveness comes from the primer compounds when they burn, forming salts. I'm shooting Yugoslavian surplus, brass cased, heavy ball(AIM). All my Mausers shoot well with it, especially the Persian. Nothing but 9&10 ring at 100 yds. If you plan to put the rifle away for an extended period, as in several months, then I would run the old hot soapy water routine. If all this still puts you off, consider loading your own. I still load for my Turk. Much cheaper than commercial ammo, and with a little experimentation you might find something that can really bring out the accuracy of your piece. I can't afford $1 a round, but .25 to .35 is not so bad. You can get everything you need tool wise for about $200. or so, and components are readily available. And of course with more die sets, you can do other callibers, too. Saving about .70 a round, it doesn't take long to make back the investment! And it adds a whole other dimension to the sport. I can do this when it is too wet, cold, or hot for other activities.
