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?
Hey cspenser, welcome to the browning owners community!! I haven't personally used the boss system so sont have much input there but it sounds like a touch call. It seems you have your current a-bolt pretty dailed in, how far out are you normally shooting?
Thanks for the reply. This gun will be used mainly for 300+ yard shots. I have been doing all of my hunting with it, but we do a lot of walking on our land, an I'm looking to go to something shorter and a bit more portable for most of my hunting which is under 300, most likely a 308 BLR. My 300 will end up being for long shots and larger game, which I hope to be able to afford to hunt at some point.
I have the Abolt stainless stalker Lefthand in .300 win. mag w/BOSS. The BOSS is definitely worth every penny you pay for it. Recoil is reduced to almost .243 level allowing you to concentrate on the shot. I did a lot of shooting and finally got a setting with 165 gr. bullets that shot 3 shots under .250, my elk load with 180 gr. with full length sized brass comes in at .520. I'm sure you lose some velocity but I've never noticed it. I shot a nice 5X5 bull at a lasered 425 yards that shot through both shoulders and kept on going, dropping the bull in it's tracks. I have taken 3 whitetail bucks at distances in excess of 300 yards. 2 at 400 according to my Leupold scope rangefinder. I didn't conciously think about the distance with any of them, I just shot. This is my long range, outwest, rifle. I would be happy if every rifle I owned had a BOSS on it. Loud though. That's the only drawback.
ROFL all these years later my Boss .300 wm does the same thing with my 150g hand loads with .336 sub moa and 200g .536 x3 at 100 it’s almost like cheating.. I just ran some factory Norma to get some pre-fired brass and 20 shots with 15mph winds were all in a group the size of a handball!! I want to somehow find other Boss rifles but there is no guarantee I will get as lucky as I did with this rig!! Hearing those who have a Boss and got it dialled in just KNOW.. they have Tuners today and some swear by it!!
