Thanks for the info guys, very helpful. Barrel still has crest and has 7mm stamped on the side. I put an empty 7mm cartridge in and closed it and still a little wobble.I picked up a 1916 Spanish mauser recently. It was in rough shape but I got it all cleaned up and it pretty again. One question I have. With the bolt closed and locked, there is still a little wiggle in it. Is this normal? Is it safe to shoot?
Yeah, I'll take it to my gunsmith just to be safe. ThanksThat's not a sure way to check the caliber. Chamber cast & mic the bore. If it is 7mm and you have wobble with a fired case you need to take it to a gunsmith and have the locking recesses in the receiver checked for wear and set back. Spanish made small ring Mausers are susceptible to that.
