I have a Remington 700 BDL in 300 Win Mag that has a shot-out barrel. I ordered a new barrel and am considering having it chambered in 300 RUM. Going to use it for hunting and some LR shooting. Other than mag length, are there any other things I need to consider? I reload and have all the components for the RUM. Just want to make sure the bolt face, action length, .... won't be an issue. Thanks for your help!
