Sample of one out of one.
Recalcitrant 25-06 that refuses to shoot 100 grain TSXs at a respectable speed is not the least impressed with the rubber donut. Never made so much as an iota of difference in the size or pattern of groups, shot 2 inch 2 in 1 out groups throughout the testing.
I just accepted it as karma for putting something as stupid looking as a rubber donut on one of my rifles as was thankful none of the other rifles decided to go on sympathy strikes.
