[QUOTE="Bob Beck, post: 710100, member: 41555"] Low-BSC: "bearing surface compression" in other words, barrels have lands and grooves, we use the term flats and lands. It is a different surface inside the barrel that impacts the bullets jacket differently. It seems to compress the bullets jacket more then groove it as the bullet passes through the barrel. This in the long term has proven two things for us. First, faster velocity potential. Second, potential extended barrel life due to less friction. Not to mention, that this type of rifling works well with softer or thinner jacketed bullets. This is something that McMillan has used for a long time, proving to be a superior componet of there rifles. [/QUOTE]
