As I told before the reason the 7 mag is not in the target bunch is it burns more powder and therefore the barrels will not last as long. So they are not used in F class. As far as not winning there I doubt any have been there. Biased garbage? You are pretty proud of yourself. Ignorant clown? &^%$ you. By the way I am not biased. Competition accuracy is an ongoing endeavor. As far as competition shooting principles are principles. People look for an ongoing advantage. How many records do you own? I do not own any. Men come in and I build what they want built. Most now like the 6,s. And no I have never been to your matches in PA. But that is a small sample size of the whole country.
