Most of you will not notice the difference unless you carry out this operation AFTER swapping your factory Norc barrel with a Match barrel (read: Krieger, Hart, Douglas, Obermyer, Mike Rock 5R, Lilja, etc) and properly bed it in a match specific stock.
So there, don't bother unless you do all of the above FIRST. Save your money, buy practice ammo and come out to your Service Rifle matches, like Ton45II, who turned up last year, then kicked my ass !![]()
