Jameyf,
I was also interested in a Browning rifle, what's your opinion on them? Does the Boss really work?
If I only had one word to answer I would say yes. However, I'm not limited to one word so I'll be sure to clarify my position on the BOSS system after using it.
Pro:
With the muzzle break it's a pleasure to shoot from a recoil perspective.
It does affect accuracy in a positive manner.
Cons:
LOUD...LOUD....LOUD.
shorter barrel to make room for it. Browning says no meaningful loss, but I have doubts.
too much to consider for hunting
Overall, if I were using the gun for a bench rifle, it would be ok just for the accuracy. But, then again, I would build a more accurate gun instead of try to "fix" something with BOSS. For a hunting rifle, I can say I would not recommend the BOSS system because there is NO real benefit from it on a 270 or 30'06.
I purchased my A Bolt stainless stalker with BOSS used. I was just starting to hunt/shoot. For ME, it was a great first gun. I was able to use the muzzle break feature to shoot without much recoil. I still notice a flinch once in a while (mainly from the noise WITH hearing protection), but I KNOW it would be much worse if I would have just started with a 270 without a muzzle break. Now that I have 2 deer behind me, I felt like I wanted something a bit nicer. I traded the A Bolt for a Sako 75 stainless synthetic. I can't think of a single thing about the Browning that is as nice (much less nicer) than the Sako.
IF you have the cash for a new Browning with Boss, you should at least take a look at the Sako 75. The Sako is still probably about $200 more, but it is guaranteed a good shooter from the factory. I just received my rifle last week and I haven't gotten to fire it yet, but the gun is much nicer feeling and seems more like what I wanted. Just a couple things that really stands out differently in the two:
A-Bolt you must be off safety to unload. The Sako has a special button to cycle the action WHILE still on safety.
Sako 75 trigger is better and is EASILY adjusted down to 2 pounds. I haven't choosen how light I want to get it yet. The A Bolt is adjustable, but I didn't feel it went as light as the Sako will go. That may or may not be a big factor on a hunting rifle.
The synthetic stock on the Sako is nicer with rubberized grips in the two key areas for holding.
Larger magazine capacity, but that isn't an issue for me
and shouldn't be for anyone with a 270 shooting the daily limit of 2 deer or less where I am.
