Picked a 93 Mauser in 7x57 bore and crown are good it is one that has the hinged floorplate the stock is a nice commercial one but barrel is not free floated drilled and tapped. I put a scope on it group was the size of a dinner plate if you could call it a group. I was using Remington 140 grn corelocks . I am thinking about trying 175 grn bullets or free floating barrel all screws are tight. Well except maybe the ones in my head. Any thoughts or advice is appreciated.
