Argintine Mauser?
Guy here at the house has a old rifle.Says"MAUSER MODELO ARGENTINO1891" Manufactura Lowe Berlin .He said he thought it was a 7.62 of some sorts I tried to stick a 7.62 x54 in the chamber no go tried a .308 no go .It does not have the piece running down the bolt like for crf on regular mausers and Winnies.Any Ideas what this is or caliber ...........SWAMP Told him I would give a $100.00 BTW it does not have a floor plate like a Mauser but looks like a Nagant on the bottom.
