Hard to read I know.... I would highly recommend you switch from the TSX to the TTSX, your BC will jump from .408 to .450 (Barnes has been known to be conservative with their BC data) & should provide more reliable expansion when the range gets "out there". Magnum is a favorite of mine in 6-284, you should be pleased with it.
