[QUOTE="Mysticplayer, post: 35201, member: 8947"] Just finished with my drop table of my 6.5 and 140gr Hornady SST bullets. Would appreciate if others could verify the BC based on the following data. Muzzle vel is 2975fps 10ft from muzzle. drop/come up at 800yds 15 min, 700yds 11min, 600yds 8min, 500yds 6min, 400yds 4min, 300yds 2.5min. Ranges verified with a Leica 800. Come ups based on Elite 4200 6X24 turrents. Come ups were repeatable. Amount per click has been verified at 100yds. All drops are based on a 100yd zero. From the program I am using, I am getting some very high BC's. Would love to see what your program says. Conditions are sea level, 85 F, 30% humidity. Appreciate the help... Jerry [/QUOTE]
