i was told its the same as a 7mm but 7mm shells won;t work. the only thing on the rifle says mouser, tried alot of shells and the 7x57 mouser shell was the only one that works but doesn't shoot accuate, it flip flops and the pattern is like a foot away from each other at 20 feet . somethings wrong, any suggestions
Contrary to the implications of the word "mouser", the Mausers are not intended for shooting mice! IF you are shooting 7X57mm rounds in yours, and accuracy is as you describe, could it be that the 7mm (.284") bullets are too small around?? If so, but the 7X57mm ammo is easy to chamber, I suspect your rifle may be an 8X57mm (7.92X57JS) that uses .323" bullets instead of being a 7X57mm.
Ask a knowledgable friend, or the local gunsmith, to help you determine the correct ammunition!
