I am shooting in Ohio,very flat.I don't have access to a good chronograph,just the cheap one that I have.I am using a nightforce scope,bases,and rings.How much can published B.C.'s be off from actuall B.C. results?I am using a bushnell elite LRF also.I thought everything was good,I figured I was shooting 2660fps,with a b.c. of .711(sierra'a claim),that worked at 300 yds and 492 yds.But when I shot from 810 yds,I was about 10 clicks(1/4 moa) too low.
