For those of you who shoot the 300gr SMk how far from the lands has gave you the best accuracy. I am just tryng to save some time and ammo and get a good starting point.
Agree with above post, all rifles are different you must experiment with your rifle to see what it will and will not shoot some of mine shoot good at different lengths from the lands and even against the lands.You need to experiment and document if it works you need that info!!!Good luck!
