I got my real numbers for my 16" 6.8 spc ARP using factory Hornady 120 sst with Omega suppressor. Can someone do me a solid and compute my numbers for 2475 fps in MOA. I think a lot of folks use a similar barrel and bullet combo.

5 mph5
150 yards .2 Mil
200 yards .2 Mil
350 yards .3 Mil
300 yards .3 Mil

Multiply mils by 3.43 to get MOA.
Double that number for 10 mph.

I'm not gonna do everything for you. grin
