Bull Barrel for Browning BAR in 300 Win Mag?

I guess it depends on ones definition of "bull" barrel. I think of a 'bull' barrel as a large diameter (an inch and a quarter) straight taper...

One of the obstacles in trying to put a "bull" barrel on a BAR hunting rifle is the alignment of the gas mechanism that drives the action open when fired... there is only so much room from the center of the bore to the bottom area of the action. The gas piston needs to be in an exact plane. It can't be just attached on the outside of a 'bull' barrel. The assembly could be machined a little to accept a larger than factory barrel, but a 'bull' barrel I still doubt.

Perhaps have as heavy as possible barrel installed with a taper that allows a larger muzzle diameter... even a 'swamped' taper...

I have a funny feeling had the OP asked about putting a "bull" barrel on an M-14 clone you would have deduced that he ment a "heavy" barrel! There's nothing wrong with admitting you don't know everything about what can or can't be done to firearms! Just saying!

OP you should try contacting these folks... h ttp://www.accuracysystemsinc.com/index.php If they can do it with the Remington 7400 & 7600 they may just give it a go with the Browning semi-autos! Keep us posted with your findings!
 
I think its a good idea, I had corlanes install a 25" bull barrel on a stainless stalker A-bolt in 300 WM, and then bed it into a Richards microfit target stock, its much too heavy for the recoil to be bothersome but its a bit much weight for any lengthy hiking. 1.25" fluted bull barrel makes for a heavy rifle.

I'd post pics but Im not that savy on this site.

Your vision is rather weird to say the least...

Not really a doable project. It won't be possible to install a bull barrel and use the gas porting that operates the action. A slightly heavier barrel with a different profile could be custom fitted. There are no aftermarket barrel assemblies that I am aware of.

I think it is a ridiculous concept for a long range precision rifle...

Gun tech said the same thing in the 2nd post. He repeated himself in more detail later. Review the OP's other posts since last his joining last year. He doesn't want real answers from here.

To the OP. Get on the f'n phone and talk to the smiths that advertise full custom shops. They have websites and phone numbers. They will tell you why your vision is flawed and then maybe explain that they don't want to be associated with such a project because of the cost, high difficulty, and incredibly limited market (they will probably say they're too busy). If you throw enough of money at them, someone will try to do this for you. Once the project is done, please post the cost, reliability, and accuracy of your rifle. If it's inexpensive and works great then us doubters will be shone to be full of used dogfood. If we don't hear from you we were right.

Note; just because the military did something doesn't mean there was any sense, logic, or reasonable cost-benefit-analysis involved.
 
$600 u.s. for a Douglas Premium barrel with a heavy taper installed, able to withstand sustained shooting, easily hold 1" or less at 100yds.

Considering the labour required I think that is a reasonable price. Go for stainless, it will last longer. I would also think it will probably do better than an inch... I have seen many factory hunting BAR's shoot under an inch (3 shots).

That's what the gunsmith said but he didn't want to be overly optimistic. I've found a BAR locally for cheap that shoot's like crap. I haven't seen it yet but in case it is crap I'm looking for a Browning BAR Safari in 300 win mag, cheap.
 
I shoot a bar markII safari in 300 mag. I dont know why you think they are inaccurate.. I get very good grouping from mine. I use mine for hunting mainly and it has taken many animals.
I dont know if the BOSS on the barrel helps maybe but i can clover leaf no problem even with cheap federal ammo.
 
Not all of them are inaccurate. Apparently about 20% of them are. Browning's acceptable accuracy is 3" at 100 yds. A google search will show that a large number of BAR owners get unsatisfactory accuracy from their rifles. I'm looking for one of these inaccurate BAR's so that I can mod it.
