so i went and shot today with a friend. I have been shooting at a little over 800 yds. today though we had to shoot out the bed of a pickup to get over a small hill. we were shooting at 600. i couldnt really load the bipod or even get behind the rifle very well. The muzzle jumped vertically quite a bit, this doesnt usually happen. I hit about 6 inches high. would muzzle jump account for this? and if it jumps left will it throw the rounds left etc. i searched and didn't really find an answer. I know i wasn't behind the gun very well and couldnt really drive it very well. So really just wandered what effect muzzle jump in any direction had on the desired impact. thanks
