I have an Omega and shoot both 200 and 250 gr. Shockwaves w/ 110 grs. of 777. They both shoot 1" groups @ 100 yds. The 200 gr. bullets run about 2100 fps over my chronograph. I have shot them extensively out to 200 yds. and the bullet drop for the 200 Shockwave is as follows.
50 yds +2", 100 yds. +3", 150 yds. -0-, 200 yds. -6" .... Shooting 100 grs. should not make much difference. Smacked a big doe in Delaware last friday @ 148 rangefinder measured yds and held right on, dropped her in her tracks. I love the 200's for deer.
