i took it out and put a box of 7x57 and it worked great. if anyone is curious i made a video of it with some other rifles and one of the handguns i own. a day of fun. what was amazing was the recoil of this mauser. i was using the truck to brace agains and the recoil was so strong it kept knocking over the camera i had on the hood.
i cant hit the broadside of a barn with this thing and my shoulder was multi colored afterwards and for about a week (note to self, find recoil pads for mauser and shotgun) but it was well worth it
