Is anyone still using the Browning B.O.S.S. rifles? I don't recall what year they came into play, but I bought a .22-250 at the time, over time followed by a 7mm RMag Stainless Stalker, a Win model 70 in .338, and finally a Win Model 70 in .270.
I was fascinated by the process at the time, and with the .22-250 I diligently worked to get the smallest group possible in order to get into the contest Browning was promoting. Fortunately I never consistently achieved my goal in time and ultimately someone with a larger caliber won with a group I would never have gotten close to.
As time went on, there were less raves and reviews and it appears interest has diminished, and I wondered if any FL colleagues are still using them.
I rather quickly got the impression that tuning the BOSS successfully pretty much replaced the need for exhaustive powder-charge increments in establishing an accurate load. However, if a different bullet was used in the same caliber, one had to re-dial the "sweet" spot all over again.
I did get a fabulous 200-yard, 10-shot group with the .270 but as time went on the groups started to expand to the point that I had the rifle re-barreled into .25-06 without the boss. The .338 was great principally because the recoil dropped into the .270 neighborhood, but, of course, that would have been achieved just with a muzzle brake. I sold that one just because my chances of going out west again diminished as my age increased. I still have the 7mm and I'm quite happy with tight groups with both Hornady 162gr and Sierra 160gr at a BOSS setting of 7.0, so I stopped experimenting with that one.
I'm back to trials with the .22-250, comparing Hornady and Sierra 52gr Match bullets as my records reveal good groups at both 3.4 and 4.0 settings, and I need to confirm those findings.
Has anyone else had good or bad experiences with the BOSS?
