RE: What do you think about 250 grain T/C Shockwaves...
I doubt it. In my Black Diamond, with three 50 gr. Pyrodex pellets and at 8,000 feet in elevation, three inches high at 100 yards only put me 3" low at 200 yards with the 250 Expander MZ. I think the 250 Shockwave shoots a couple of inches higher at 200 yards with the same load, and isgoing about 150 fps faster - although I am currently loading it with 130 grains of Pellets.
