They aint worth squat. The 300 RUM will never last and most people don't want to put up with all of that recoil. You should send it to me.

Depends on exactly what gun you have there. Give us more info other than the cartridge. Is it the RMEF endorsed rifle?

BTW there is no such thing as a Winchester ultra mag but there is a Remington ultra mag.


P.S. welcome to the boards.
