I loaded up some Barnes 85 TSX with Hodgdon Superperformance powder.

Heres what I got.

46 grains----3011, 3069
46.5 ----3130, 3133
47 ----3191, 3201
47.5 ----3268, 3306
48 ----3315, 3348

48 grains was sticky to extract.
Looking at the velocities 46.5 or 47 seems like the point where the consistancy was.

The cases pretty much all look identical the only really flattened primers came from the 48's.

For my personal choice from this load I'll go with the 46.5 load.

These were shot in a 20" barrel Handi-rifle.
