I had an Abolt in 300 win with a BOSS and it was very accurate. I then had a machinist buddy of mine turn down the BOSS on his lathe so that it was barrel contour and just as long as the threads,in other words a cap. Looking at it you had to look close to see that there was anything there at all. Result, it still shot lights out with the same load as before. Sold it to my nephew and he says he is keeping it because of the great accuracy. So, accurate barrel? Yes, and the BOSS made no difference. I had one other, a 7mm08 Browning that was a 2 inch gun no matter what I did. It's gone, too and there will be no more. Guy brought one into the shop last week, told him I wasn't interested. Said he had $1200 in it with the buckmaster scope on it with a bipod. I told him it was worth maybe half that, and that would be retail price. Used Brownings don't fly off the shelf here. I tried to get $450 for an A-bolt in 7wsm, SS, no BOSS with Talley Lightweights, no takers, so I took it home.
