Alright, it's been awhile since I've talked to you good folks on here but I'm needing some input again. For those of you who helped on my 300 mag decision from Nighthawk Custom, thanks a million. Love the rifle and it is a dandy shooter. I have a .375 RUM XCR and I'm not very impressed with it. However I'm seriously considering making a long range shooter out of it with the 350 gr SMK bullets. I'm thinking of having my gunsmith true the bolt for me, putting a PAC-NOR 6 groove 1:10 twist 28" barrel on it, and dropping it in a McMillan a-5 stock with a jewell trigger. Does this sound like a good idea or am I gonna be let down pretty hard? Has anyone built this caliber up yet? Thanks for any help.
