It’s a matter of taste I know but I’ve never had anything for either of these cartridges at all.
If choosing between them I’d go 7RM because of high BC bullet selection that isn’t going to have the recoil of the .300. Seems easier to place a bullet where it belongs with 7RM.
There isn’t an animal in NA that would be able to tell the difference between hits from these cartridges assuming similar bullet construction and placement.
