I really need to clean up a few older guns I have, plus I'm getting something for Christmas(either a Yugo Mauser 24/47 or a Yugo 59/66) that I'm thinking will be soaked. I've also got a few Mosins(why I posted it in here) and a .308 Enfield that needs cleaned up. I know how to get it off the metal, no big deal. But what about the stocks? My oven is not big enough to put them in, plus it starts at 170 degrees. I know at a certain temp(like mid 300's isen't it?) that cosmo will ignite, so I'm wanting to be careful LOL. I was thinking either a small steamer or maybe a heat gun. I've also heard people say to get one of those metal trashcans and put a few bulbs in the top of it with the gun stood up. I live in an apartment right now so space is an issue, it will have to be done outside. What do you all suggest? One more quick question. Is it safe to use mineral spirits to clean the cosmo from the bore?
