I had tried TAC in mine, best accuracy I could do was 1.25 @ 100 yards. Honestly that would be good for 300 yards or so, but decided to see if i could do better. Trying R7 right now, shows promise, but maybe 50-75 fps loss of velocity which in the scope of things is nothing!

......the occasional hunter wielding a hopelessly inaccurate rifle, living by the fantastical rule that this cartridge can deliver the goods, regardless of shot placement or rifle accuracy. The correct term for this is minute of ego.
