Browning rifles with BOSS system

i've been doing quite a bit of research and i've come across a very interesting line of rifles with a special feature called BOSS, it's a adjustable choke for the tip of your barrel

has anyone ever dealt with one in person and has experience with it?

i was thinking of buying the Browning composite stainless steel stalker -BOSS for 1,200$ is there better for that price?

if so what and why thank you for the feed back

Au contrair...it is not a "choke", it is a barrel weight adjustment system that supposedly lets a shooter "adjust" the vibrations in the barrel when it is fired to get better accuracy.

Not really a "choke". I have one in 22-250 and it is a shooter. Loud as hell though....unbearable loud.

I have a Browning Safari in 30.06 with a BOSS system. when it is "dialed in" I have 1' groups out at 200 yards. However, "dialing it in" is a task. The numbers must be zeroed on the sysytem then the number dial lock tited. If it is allowed to shift you have just wasted a lot of time and money. Then you have to pick the round. I use a remington accubond 30.06, 165 grain, with a Nosler tip and boat tail bullet. Buy a few boxes of your ammo. I would shoot three round groups. Ajust the setting either way(right or left), but get them to come together. Keep working untill you have it dialed in. The Boss is super loud and does help with the recoil. Once it is "dialed in" you will know the sweet spot. I only use one type of ammo, but you can keep a card of the setting if you change ammo. There was a time when some ammo had a starting number to set the Boss so it would take less time to dial in. If used properly it adds accuray that only the bench guys know.

If you are asking me, all I can say there are prolly other people here that can answer that question better. I do a lot of deer hunting so I wanted a medium caliber with a flat shooting bullet that won't break my arm or bank. I think 30.06 is a good all use bullet. You can use 185 grain or go light with a 155 grain. I quess it depends on what you shoot at. I feel I could take any animal in North America with a 30.06. Just my opinion before the hate posts appear.

madhat-
I used to live in Reno and have hunted all across the west. A 30-06 will surely do everything just fine. May not shoot quite as flat as a 270 or 25-06, or have as much on-paper oomph as a 300 Magnum, but it will work just fine. And all that talk about needing a super-flat shooting rifle is based on a small percentage of the shots you will ever be given. Just to give you a perspective, I have hunted with a 7X57 on and off for years. My farthest shot while I lived in NV was about 400 yds, easily doable with a 30-06. So yes, some guys with their 257 Weatherbys or 7mm RUMs may shoot half a mile, but generally you can get closer without too much effort, and your shot will be more likely to hit what you are aiming for.

BTW, you can get the BOSS system without the ports on the BOSS, it will be a lot more pleasant to shoot.

I was working for American Rifleman when the BOSS system came out.

I thought it was a bunch of hooey when I first heard about it.

Then I got to shoot one, and was thoroughly convinced. The weight changes the harmonics of the barrel, and it's absolutely amazing how quickly you can dial in just about any load.

I have the BOSS system on a Model 70 Winchester FW..300 win mag....I have no problem with the noise..heck it's loud anyway....lol....But it is amazing how much recoil is reduced..and it is super accurate....I have the same gun..same caliber..no BOSS..also....So I have a good comparison....

how easy is it to dial in the boss? what if your boss is set for say 150 yards and a animal is 250 yards, how easy it it to dial in the boss to hit the target? what if you shoot? how far would it be off if the boss is dialed in wrong, sadly never using one i have to ask all these questions

You don't dial it in for a specific range, you tune the harmonics of the barrel so it shoots the best possible group. Then, if you are sighted at say 200 yds and an animal pops up at 300, you know your load is shooting the tightest group possible and you can hit the animal at farther ranges because the groups are consistent and shot dispersion will be minimal.

Scorch, I agree with your view on long range game shots. Madhat's choice of a 30-06 will serve him well up to moose. If he later chooses to take on brown bear, I suggest moving up to somthing like the 338. For now buy the 06.

The boss is as described above but it comes in two forms: (1) with muzzle brake which is pictured above -- and is the loud version), and (2) no muzzle brake. Either alters the vibrations, but the muzzle brake version affects the barrel rise and the felt recoil (a 30-06 round feels like a 243, for example)

I wouldn't buy the rifle with the BOSS, but I would with the plain barrel. I handload and the BOSS won't do anything I can't accomplish by careful handloading. Noise when hunting without ear protection is the primary concern, but tuning the rifle for each different bullet weight/manufacturer is a pain.

I've recently shot Browning bolt rifles without the BOSS and they shot very well indeed, even with factory ammo!

I had a Browning BAR MkII Safari in .30/06 with BOSS (Ballistic Optimized Shooting System).

Once I had it dialed in to the different ammo types I used, it worked great. It is a good way to dial in your groups.

Here's a link to Browning's recommended starting point for tuning your BOSS to your ammo type.

My primary hunting rifle for the past 6 years has been a MKII BAR in .270win w/ BOSS. Let me first say this Browning is very accurate, up there with bolt guns. 5/8"-7/8" groups at 100 yards consistently year after year.

As others have indicated, yes the ported BOSS does add muzzle blast however the advantage in recoil reduction and faster followup shots outweighs that (at least for me). I have tried a few setting on the Boss system. The first of which was the factory recommended "sweet spot" for the brand and bullet weight of my chosen cartridge. Groups were mediocre with this setting. Interestingly enough the best groups I get, with my chosen cartridge, is setting the BOSS to "0" and the micro-adjustment to "2".

Anyways, that's my personal experience with the Boss. I love the reduced recoil and if I'm honest, I think it looks pretty cool too

BOSS is not snake oil ...

I built a Mauser in 243 several years ago and I did a fair bit of research (patent office is a good place to get Browning's engineers version of the story) on the BOSS and built myself a non-brake version. Contrary to what some might tell you, it CAN do things that you can't do with just careful reloading. For example, it allows you to make your loads run as close to maximum for your rifle as is safe and then lets you tune the rifle so THOSE loads are also the best shooters ... sometimes you can get lucky and have the max loads be what your rifle likes without a BOSS, but it happens every time with a BOSS. Prairie dog sized targets at 300+ yds are non-issue for that 243.

All that being said, I wouldn't get the one with the brake for the hearing issues that accompany it ... but the non-ported versions are winners.

It's not a choke, it's called a "tuner". It allows you to match the way the barrel vibrates to a given load, rather than changing to load to match the way barrel vibrates.

It works well, although there is a fair amount of setup for a given load. So it makes sense IF you plan to use one specific load in the rifle. You'll shoot up a fair amount of ammo if you change around a lot.

Most BOSS rifles come with a muzzle brake weight, which has the advantages (reduced recoil) and disadvantages (hellacious noise) of any muzzle break. Browning does sell the a non-muzzle brake weight as the CR version.

Could one not achieve the same goal - reduce the harmonic vibration and improve accuracy - by using a barrel de-resonator? You could avoid the increased report caused by the Boss system.

The goal isn't really to reduce the vibration, but rather match the vibration to the barrel/load. As noted above, you can get a non-muzzle break version of the BOSS weight that won't increase noise.

these guys have pretty much summed it up... I will add, it does reduce the felt recoil alot... perhaps both because of the additional weight at the muzzle, & the ports... I have both a 338 Win Mag & a 375 H&H Stainless Stalkers, both with BOSS... both are more accurate than I am, & neither one is much different than shooting a .308 / 30-06

BTW... I don't personally think it's louder than the same rifle without the BOSS & with a 2" shorter barrel... the ports are not angled towards the shooter, so the "effect is no different than a 2" shorter barrel

Some of the other posters summed it up nicely on how the BOSS works so really nothing I can add to that. I will say I have the BAR Safari in .270 and just using the recommended settings in the owners manual, can constantly put 5 rounds of Winchester 130gr Ballistic Silvertip in under 1" at 100 yards. I wouldn't be surprised if I couldn't improve by messing with dialing it in but I'm very pleased with the performance so I don't bother. It is loud if you're shooting off a bench that has a roof over it but out in the woods or field, you don't even notice it. It's amazing how much it does reduce recoil and if you are sensitive to the blast, they also come with an attachment that's not ported that functions the same but the recoil and muzzle report is the same as any non-BOSS rifle. If given the choice, I will opt for the BOSS everytime as I think it's that beneficial.

As far as caliber goes for your intended purpose, the .30/06 is a fine choice but I would take a long hard look at the 7mm Remington Magnum. A little flatter shooting and with very few exceptions, harder hitting then the '06 and ammo easily available although not as many options in various weights as the '06. A little much for Pronghorns but not overkill and with some of the distances you may actually find yourself shooting at, the extra punch would be appreciated especially if it's on a large bodied Muley or an Elk.
