1" isn’t bad … I personally shoot all of my rifles to 1/2" @ 100 yards … including big calibers. The smaller the caliber the easier they are to dial in since recoil is a lot less of the factor. Are you just shooting off of sand bags? … I shoot off a full rest, that encloses the gun itself, and used fine micro-adjustments to center the cross-hairs on target … all you have to do is squeeze. Takes a lot of human error out of the promblem … although a good flinch will still throw you off.
