[QUOTE="jwp475, post: 101722, member: 3776"] [ QUOTE ] Just a couple "seat of the pants" things I've seen and heard. There was a guy on one of the forums claiming to be an ex employee of barnes and he said that the rings do affect the bc cosiderably. From what I've seen in the gun magazines where they;ve compared actual bc to claimed I would reduce the barnes tsx by a minimum of 10%. Regarding cannelures it seems the hornady sst has one of the closest bc accurate claims and it DOES use a cannelure. They usually show up as good and usually better than a ballistic tip. It also seems that bc ratings seem fairly close out to 500 yds and then fall off on their way to 1000 yds. I guess the only way to test is to shoot and see. One thing I love about these forums is the experienced reports of the long range guys. [/ QUOTE ] I saw that guy and put no credence in his claim of being a ballistic tech for Barnes.
