[QUOTE="aroshtr, post: 809574, member: 9176"] Since you have proven that you are hitting to the right as dial the scope (100yrd test), this will only add to spin drift error. With a right twist barrel you will always drift to the right. I assume you are using a level in your system, and the action you need to take is different depending on where the level is mounted. If you have a rail mounted, or level on your ring cap... Then you would need to make a slight counter clockwise (from shooter position with the scope). After a slight adjustment re-test like you did at 100 yards. With varying wind effects it is safer to confirm at 100 yards. If you have a scope mounted level... moving your scope without changing the level position will do noting to fix the problem. In this case you would need to rotate the level clockwise (from the shooter position) slightly. This will correct so you can either be dead on, or like greyfox said you can have your scope level set to automatically correct for you spin drift. Example: If your setup has .5moa SD at 1000yrds, and it takes 24moa elevation to reach 1000, then dial up 24moa and adjust the level so your impact is .5moa LEFT of the plum line on your 100yrd target.
