[QUOTE="Song Dogger, post: 1495548, member: 101648"] Stats for those inclined to check the ballistics: original muzzle velocity was 2875 fps with an extreme spread of 27 fps and standard deviation of 9 fps (sample of 13 shots). But, I dropped the muzzle velocity to 2750 fps to fit drops I saw at 500 and 600 yds while practicing on the Lead Sled. The 210 gr Berger Target VLD published ballistics coefficient is 0.621. Sight height is 1.7 inches. The Geovid read 55 degrees, 22.8 in HG (approx. elev 7300 ft), and -1 degree inclination. Estimates are 35% humidity and 10 mph headwind. First shot was 413 yards (Geovid suggested 5.1 MOA), later shots at 450 yards (Geovid suggested 6.2 MOA). At these distances, I think you’ll find only a couple inches of difference between the two muzzle velocities. Holler if anyone get numbers significantly different than mine. [/QUOTE]
