375 RUM with 350gr MK
Has anybody tried the 350gr MatchKing in the 375 RUM? I have this urge to put together a heavy long range 375, but I don't really want to deal with the CheyTac case or action sizes. The RUM seemed like a decent option. I'm not sure how fast this case can move a bullet that heavy, but I'm expecting somewhere around 2700 fps.
I ordered a box of the 350gr Sierras and some 375 RUM brass so that I could put together a few dummy rounds as inspiration. Those should be here in a few days. I'm not sure what the OAL will be, so I don't know what action I would need to use in order to have a repeater. I'm not really worried about that though.
