I am thinking about a new VV Arms Encore barrel in one of the Remington short Mag (7mm- 300)and need help. Cant make up my mind on witch one and what twist. It will be 26 or 28 in. stainless Fluted. I think I want it twisted to shoot the 140 gr. in 7mm or the 165 in the 300. Witch one of these calibers would make the best choice for a all around do all rifle ?
