[QUOTE="Ian M, post: 23485, member: 25"] Wyo, I do not have access to any ballistic programs to compare my chronographed velocities to. My latest Barnes manual says that the B.C. of this bullet is .476. I must admit that I am not much good at playing with computer numbers or theories. That is why I go to the bother of shooting throught the Oehlers downrange, I get real numbers, plus it is a neat challenge. If you would like to check my numbers with a program here are some downrange velocities. 168 Barnes XLC, 26" Barrel Distance Velocity Muzzle 2608 fps 100 2428 fps 200 2209 fps 300 2050 fps 400 1919 fps 500 1763 fps My buddy thought that he was getting more muzzle velocity but we shot at 5 yards (15') yesterday and got 2608 from 45.5 gr. Varget in his rifle. This load shoots very near .5 MOA out to 700 yards if we do our job. [/QUOTE]
