[QUOTE="WildRose, post: 1037963, member: 30902"] A couple of things come to mind. One, it could be a difference in how the rifling is done between the two companies. Two, and the one I think is probably more likely is that you may well have a buildup of copper and carbon in the barrel that makes it appear as though the rifling is not a pronounced as it actually is. I've seen this problem in a lot of older used rifles and pistols. They still shoot OK, they just look like they are turning into smooth bores. Remove the buildup and remove the problem. Keep in mind though riflings don't have to bite into a bullet deeply to make it spin but you can get into some pressure problems with a barrel that has such a buildup of years worth of carbon and copper. I'd suggest using a pretty aggressive copper and carbon solvent alternating between the two and give it a really good cleaning until you see no evidence of either on a dry patch. As said above if your rifle is still shooting accurately you really don't have to worry about the barrel being shot out and barrels can last a long, long time if you simply don't shoot them hot and keep on shooting particularly in calibers like the 7mm Rem and 300wm . Some calibers are inherently hard on barrel life but neither of those are. [/QUOTE]
