[QUOTE="Barrelnut, post: 1732059, member: 74902"] A SD of 10 would mean that 95% or the rounds would be +20 or -20 FPS of the average. And that 65% of them would be between +10 and -10 FPS. My 300 RUM with a 210 VLD will have an impact change of +/- .5 MOA at 1000 yards with a +/- 20 FPS change in velocity. That .5 MOA at 1K is a hair over 5 inches. With a 10 inch kill zone .5 MOA is all I could afford. Kinda supports what others above have said. A SD of 10 or an extreme spread of 20 FPS would be about the limit for 800~1K shot. [/QUOTE]
