I picked up an M 24/47 (Yugo Mauser?) at a gun local shop here in MA, complete w/ all the tchotchka that come with it (bayonet, sling, clg. kit, ammo pouches) plus a box of 8mm Yugo ammo (1200 rounds), as a package, for 150 bucks. I then spent a couple of days scrubbing out cosmoline with stiff nylon brushes, detergent and lotsa elbow grease. What a gem- it was obviously FTR'd and has a nice shiny bore.
The first time I shot it this week, the cosmo, due to heat, still sweat out of the handguard, so the stock pieces got the treatment again- and the wood turned grey. I'm told that is the cosmoline, a lanolin derivative, still sweating out from the pores of the wood. Once I had scrubbed the grey and gunk away, I've been rubbing in a coat of boiled linseed oil every day- the Mauser looks even better now.
You guys are right- these babies are accurate as hell, but with the ammo I've been using, the recoil takes some getting used to. 30 rounds a day is about all I can handle. These guns are a lot of fun- I think I will get some Turkish Mausers and revive them, too. Get them- and their ammo - while they are still cheap and plentiful.
