I think it is worth noting that the OP was asking about a BR rifle and not an F class rifle. It is also worth noting that "team savage" has done very well in recent years competing in F class matches. However, F class and BR are not the same thing. Different skills and different requirements in application from the equipment, including the rifle, are apparent, hence the difference in NAMES of these competitions.
There are a lot of people who disparage BR competition especially short range group matches, because they feel that it is really only a competition of the wallet rather than of shooting skill. Certainly the quality of the rifle counts more in BR shooting than in some other disciplines, and those who have never competed in BR and have maybe seen a line of rail guns shooting 100 yard group targets might be excused for thinking that it's not a skill driven event.
Still, I have had it proven to me that a different skill set applies in BR shooting. If I were to swap rifles with Tony Boyer, Rick Graham, Jack Neary, or Jackie Schmidt, I am sure that they would do better than me, even when I'm using their equipment. By the same token, I can edge out another competitor of similar skill to mine and who is using an inferior rifle, if mine has been built to purpose, blueprinted and his has not.
I do not mean to imply that BR shooting has more inherent worth than F-clas, silhouette, or any other type of competition. It's just a different discipline and different equipment is called for in order to be competitive, and that's what the OP was asking..... BTW I have been able to find an IBS BR match that was won by a competitor using a Savage rifle. It was listed in the Precision Shooting Magazine (IBS newsletter) in the match results equipment list section. Since I have several dozen of those to look through I am not going to go dig them out of the attic and cite date and location, since I have already done that some time ago when posting to a thread in the Factory/Hybrid section of the benchrest.com forums where someone had asserted that no Savage rifle could ever win a sanctioned BR match...........As far as I know, that was the only one........
