Im tossing around the idea of swapping my 1x7 twist savage bvss to 6mm br. My question is, with so many companies making prefit barrels for the savages. are there any that stand out as being the best? Is there a certain rifling, number of grooves or length etc that works best? I like the idea of running untouched lapua brass. is this something that needs to be considered? I most likely wont be competing so Ill be shooting the bullets that shoot good without breaking the bank. Like the 105 a max.
