Well I went out today but changed the scope to a 3x9x40. Todays equipment: T/C Triumph 50cal, Bh209, CCI 209 M primer, 250 grain Shockwaves, 250 Hornady Low Drag SST and finally 250 TMZ Barnes. Seems to me if I use 100 grs of powder that I get around 3" high at 100yds. If I use 110 grains of powder I shoot 6-7inches high at a hundred and zero at 200yds. So far so good! I used the TMZ and they flew BAD! The first two bullets were about the same. Any other recommendations for trying a better bullet or load for Mule Deer???
