Hi everyone, I had a bit of a strange drift happening with my 222R(788 Remington). It shoots perfectly at 200 yards, but in zero wind the other day I was shooting out just past 300 yards and was getting hits around 6-8 inches to the right of where they should have been. Rather annoyed that I could not hit the rabbits I was shooting at I came home and checked the zero at 200, which was still fine. I was only using winchester psp projectiles. I have since moved to winchester/nosler CT 50 grainers but have not yet had a calm day to test them on at long range. Any ideas?
