Why do people do this? Or even recommend it?This is a nice round, in the older Krag rifles a 168 gr. bullet at +-2000 fps is a nice hunting load for deer size game. If you have a newer action you can load to the 30-06 or .308 levels so the cartridge is very flexible.
>If you have a newer action you can load to the 30-06 or .308 levels so the cartridge is very flexible.<The loading manuals I am recalling (from memory) list loads for modern actions and specific loads for actions such as the Ruger model1, there are no "Krag friendly" loads listed and only recommendations against firing in older guns.
Hot rodding is not what I am advocating, there are quite a few different action types that can handle certain load power factors and the Krag round , brass and bullet capacity, is flexible enough to accept a variety of loads.
