I've recently become aware that my sporterized 1893 FN Mauser 7x57 has excessive chamber headspace. The most obvious sign of this is new factory ammo from Federal showing signs of head separation and primers backing out as much as 0.010" past the head of the cartridge. I've had the rifle about 20 years and the old timer I bought it from was reloading for it so I know that some brass can last at least two firings in the rifle without separating, but the signs were there had he been paying attention. I can't in good consciousness sell it as a serviceable rifle and am not about to continue using it so I'm looking for opinions and options. So far this is all I've been able to come up with: 1) Wall hanger - Even if my wife would allow it, I find no beauty in looking at a useless item that bears little resemblance to the military rifle it used to be. 2) Red Herring - In the event that the government seizes bolt action rifles with 5 round fixed magazines I can give them this old dog while hiding a modern rifle. 3) Repair - A local gunsmith could set back the barrel and re-cut the chamber for about $400, but I could buy another rifle for that price. 4) Swap bolts - Not only are 1893 Mauser bolts cost prohibitive, but the handle and safety would have to be modified to fit the scope which would probably be a $200 fix if I could find a suitable bolt. 5) Part out - Sell for parts and try to get some money out of it, $100 if I'm lucky. 6) Wildcat - Fire form cases to the existing chamber and treat it like I just created my very own wildcat cartridge. 7) Cut a new chamber - Cut the chamber to a slightly larger cartridge. The 280 is close, but the 1893 Mauser can't handle SAAMI max pressures for the 280 and the magazine is too short. Am I overlooking something else that I could chamber to? I've love to hear any thoughts or opinions on the options I've explored or any that I've overlooked.
