Re: Boss on x bolts

I'm not upset, or trying to upset you.
Old rifle companies like Browning don't just slap together fad combinations in every form, for every shooter. They develop their products to a standard they can stick with in the long run.
The A-Bolts have served us well for quite awhile.

Browning isn't perfect though. They do need to improve. And they should start by communicating with customers.

Re: Boss on x bolts

There is no reason you can't do a custom rifle, X-Bolt with a BOSS.

As an engineer I can see that the Devcon Flexane 94 Flexible Urethane used to bed A-Bolts would tend to deaden vibrations the same way a LimbSaver on your barrel would. If you want to approximate the effect of the Flexane, simply put on a limbsaver band or put a drop or two of silicone sealant between your barrel & stock.

The BOSS unit will tune the vibrations on ANY rifle, be it A-Bolt, X-Bolt, or even Mauser.

I recently picked up a s/s Model 70 in .300 Weatherby with a BOSS. Haven't got a scope on it yet so I haven't shot it yet. If I like how it performs the rifle will stay in this configuration, if not I'll likely have a Christenson carbon wrapped barrel put on it & have a barrel & BOSS to sell. The BOSS is great in that it lets you control the harmonics of your rifle. A carbon-wrapped barrel has less flex & vibration when fired so controlling the vibration is less an issue.

How do you know this?
Could it be that 'less' flex & vibration, or higher frequency vibration, makes controlling of it with a tuner -very difficult..

The object of tuning is not to reduce vibration, but to time bullet release within it.

This is my understanding of the BOSS too, is that it allows the bullet to leave between the nodes of vibration.

In the interest of stiffer barrels, I am wondering how the Model 70 Laredo heavy barrels wit BOSS units reacted to adjustment (and what their sweet spots were) compared to the sporter barrel counter parts.

Re: Boss on x bolts

IMO, a tuner on anything but a Browning, as a BOSS, is merely a gimmick or an experiment.
Yes, you can put an adjustable muzzle device on any gun, and affect your grouping.
But without understanding/testing there is no reason to hope this amounts to 'tuning'.
Browning has done this testing, and if memory serves me right, they promote an annual BOSS challenge tournament.

The point blank BR crowd has found with THEIR tuners on their extremely limited guns, that tuners do not achieve the tune they normally have. ie. It doesn't affect the load they would use otherwise. Tuners for them have neither hurt performance nor helped, other than allowing abstract adjustments for atmospheric changes. You could probably do as much to a standard load with a few wraps of electric tape..
This is because they are trying to reinvent a with zero understanding, and no scientific method.
Even the rimfire crowd, who need adjustment more than anyone, have failed to define a predictable system of muzzle device tuning.

Browning is the only company to produce success here in that you can pick a load, and dial BOSS in to reasonable factory accuracy with it. This with a fairly wide variety in cartridges(not just one).
I have an A-Bolt that came with BOSS originally and shot very well(223). I changed the stock to one of their Eclipse thumbholes and then had no luck dialing a tune. I didn't know about Flexane, but recognized that the original plastic stock had a hard rubber bedding. So with nothing to loose I bedded the Eclipse with ShooGoo(close match). From this point, I could dial in tune without issue, and the gun was even more accurate than original. I've since come to believe that nothing else could have made that barrel shoot so well.
A few years later I damaged the barrel/BOSS in an accident, and rebarreled with a Pacnor in 6br(no tuner). Same bedding, but this combination will not shoot as good as the original with BOSS.
Oh well.

If I were to build a tuned gun today, I would use Browning's own non-muzzlebrake tuner on a lightweight contour, epoxy bed the pillars, and Flexane bed the action/barrel shank.
Just a matter of finding a machinist that could finish the muzzle end for it. Or, if someone made an alternative to Browning's tuner that was as good, I might go with theirs. Haven't seen that yet.

I think maybe it so the still have a selling point with the a bolt, because it seems like the x bolt is a better more vesatile action. If you could get a boss on a x bolt why would you buy a Abolt if your getting a new gun. How many people will probably buy a another new x bolt once they come out with it on thier??

Has anyone toyed around with the idea to put a boss system on an x bolt. The worst thing that can happen is you get a muzzle brake.
The boss system was designed to allow a factory rifle with a factory contour to shoot different
types of ammo with some degree of accuracy by adding weight that can be moved (Tuned) to
some degree. As far as the muzzle break part of the system it is a decent brake.

A lot of people find that if they just screw the boss all the way in and lock it down it works
pretty good.

With a slightly heaver barrel a regular muzzle brake it will work better and reduce recoil better.

I personally don't find the need for a boss system because I reload and can tune the load to
the rifle.

So I would just screw on one of the many good brakes and be done with it.

Just my opinion.

Re: Boss on x bolts

I agree with JE. I have a few brownings and I have replaced all of the brakes with the boss CR. These are hunting rifles and the boss is sooooo loud that I cant shoot them without hearing protection. The first year I had a boss I was standing about two feet beside and five feet behind a big pondorosa pine and took a bull. I was deaf for 2 full days. I thought I would never hear again. Since then I always wear hearing protection when using these rifles and like I said replaced all with the CR. I dont need the break since these are non magnum rifles and the CR stilll allows you to tune the barrel.. However I dont mess with them because I tune the load instead.
As far as the xbolt goes I was talking to the browning rep and he told me "The xbolt is new but in reality it is not as high of quality as the abolt. Basically it is a lesser version with some neat gimmiks."
