I had one in 50cal sold it. Nice rifle but heavy. I also have one with a 45cal Pacnor super match grade barrel. Its no where near as load picky and it can shoot far flatter than the 50cal. It still a total pig of a rifle so its a range queen. My ULA 50cal is the only smokeless ML i still use for hunting. Hard to beat a 7lb ready to hunt ML that can use smokeless.

Once you try one of the aftermarket 45cal barrels, you probably wont go back to a OEM 50cal barrel.
