I have a L/H stainless stalker .300 Win Mag from the early 90's. Very accurate, one shot kills, has dropped everything upon impact. I came across someone who has the exact same rifle with the BOSS system for sale. Finding a L/H stainless 300 with a BOSS is not something I've seen that often. I was considering picking up this rifle and selling the one I have. I would use the muzzle break feature mostly at the range, then switch to the CR in the field. This is mostly a long range shot rifle for me. I've heard people talk about the accuracy improvement. However I read an article about a Winchester model 70 with the same factory system, they said that there was a noticeable muzzle velocity reduction due the 2.5in rifled barrel reduction to keep the overall barrel length at 26in. The seller is a bit of a drive from me, is it worth the trouble to trade up for the BOSS system?
