I haven't shot my Mustang lately - been playing with the GP flintlock and Zouave. But I bought 100 MMP orange sabots for some experiments with .458 bullets in the Mustang. Just can't seem to get to it. Right now my best shooting/go to load is with T-7 and Gold Dots. I've posted this target before, but here's the type of groups I get with my pet load.
