As military rifles go I have many good cast boolit shooters, mainly 7x57 mm Mauser, 303 British and 8x57 Mauser. The best would have to be my Winchester Model 17 in 30.06 fitted with a Parker-Hale 5C range sight. The manufacturing date on the barrel is 03/17 and the barrel would rate 9+/10 even after many years of shooting cast boolits.
Nothing more relaxing than an afternoon on the range with this 105yo old beauty.
