Unless you are shooting a 10 lb+ rifle, it's going to be hard to shoot it from steady field positions frequently due to recoil. I had a sporter weight unbraked 300 RUM and it smacked me harder than my 375 H&H did. I'm putting together a long range 300 RUM this spring. I'm planning on shooting the 210 gr VLD at around 3100 fps. I don't expect as much barrel life as a 338 but that is why they make new barrels.
