375 RUM with 350gr MK

[yorke-1]

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.

Cutting edge 320gr BC.830 might be worth a look as well

You might call/email Sierra and ask what twist is best for that long, heavy bullet at the speed you'll want to shoot it. A 10 or 11 inch twist may be what it needs.

i have a 338 edge now and i was thinking the same thing that the 375RUM with the 350 would be good long range i would have the throught cut deep so i could seat the bullet out . my action and stk is set up for single feed. When your shooting past 500 yds if you miss usily the criter you are shooting at just stands there and lets you try agin so a fast reload was not an issue for me . buy the way my edge is for sale.
