I just got my 375 RUM back from being rebarreled by Brian owner of Shoot-Long | Long Range Rifles, Long Range Shooting Rifle was just a Stainless BDL in 375 rum but the barrel was horribly rough and fouled quickly and was very hard to clean. So I sent it to brian and he put a Fluted #5 Benchmark 10 twist 5R rifling finishing at 28" and a .750 CSR brake on it. The bolt is a Spiral Fluted from PTG with a speedlock firing pin assembly. Timney Trigger and Wyatts extended magazine box, The fit and Finish are pretty much as close to perfect as you can get.. This is the second rifle I have had Brian build, the first was a 375 ruger for my dads alaska brown bear hunt and that rifle shoots very well. I expect this one to do the same.
