I have one of the original A-bolts that came with the Boss system back in the early 90's. A Medallion 7mm rem mag. I'm 50 and its still the queen of my safe however that beautiful wood stock does have a few nicks and scratches due to where i hunt. My bolt even to this day is very slick similar to my tikkas. Was very accurate with the factory setting and never really thought about playing around with the Boss system because it was so accurate. I've taken the Boss off and put the CR Boss on just because it was so damn loud. I still use it from time to time, but now when I go, I grab my Tikka 308 because its much shorter barrel makes it easy to handle in my tower stands.
