Can anyone tell me what the ballistic coefficient of the RCBS 30-180-SP is shot at about 1500 to 1700 feet per second.
I am trying to get some sight settings for high power silhouette. Or better yet does anyone have sight settings for a 200 yard zero using a 190 to 200 grain bullet at 1600 fps. i.e. using the 200 yard target the 330 yard setting hits 15 inches high, the 385 yard setting hits 40 inches high, and the 550 yard setting hits 80 inches high.
They allow sight in at the match but I would like to be able to hit within 5 feet low or 3 feet high. They have sand berms around the target with grass below and above the berm. My spotter would hopefully see the bullet strike in the sand.
Thanks
