I have run across a 1895 chilian mauser sporterized 7x57 to 7.72 x51 nato-.308. Looks good for its age, then I read there is a warning on this rifle not to use .308 winchester ammo, too high of pressure for the action. For $200.00 would it make a good cast bullet shooter or add a few more $ and get a newer .308 that can shoot both regualr .308 and cast ammo? Being sporterized I dont think it has much collector value. Has anyone had any experince with this rifle shooting nato ammo or low pressure loads under 50,000 psi. ?
