The BOSS aint doing me right

Took my Browning out yesterday evening to do some sharp shooting.We started out at 100yrds.I shot second in a group of three,my friiend shot first and was shooting 1 1/2 in groups with a 7mm08.I start shooting and we were bench shooting by the way,I would put one hear and one there.And it was a joke I couldnt print a group with my Browning BOSS which is post 1996 after they made their change.Finally I just quit shooting it and came and got one of my REM 700s and put a 1 inch group at 100yrds,a couple of times so now my ego is back but whats up with my BOSS? Please correct me if im wrong.The boss was introduced by Winchester to stableize the amount of bullet vibration,and keep it closely the same with each shot to aid in shooting a tight group.Well Im glad I just have one BOSS or do I just have a lemon,or is there something I can do to improve the way this gun shoots?

    the boss is a tool to ajust barrel vibrations for changes in ammunition, you have to 'tune' it every time you change loads (differnt brand, weight bullet, powder ect.). once you find the 'sweet spot' for a particular load, record the setting so you can come back to it if you change the setting for a different load.

    You might have a bad one.It could be the way the BOSS is cut.The Browning A-BOLT I shot was superbly accurate and it had the BOSS the only problem I had with it was the noise.You could maybe have it chopped to remove the BOSS or just try different loads and see if it improves with different rounds.It may have to do with the caliber the rifle is in the one I shot was a .300 win mag.Good Luck.

    Finding the sweet spot can often take up to 2-3 boxes of ammo for any particular ammo. The owners manual has a chart in it that will help to put you close for a start. I don't personaly want one, but my hunting partner has one and it is accurate. I too, can't stand the blast from it, but it serves him well, I'm a rem 700 bull barrel guy.

    A great rifle with a junk scope,....is junk.

    I found a Winchester Model 70 300WM some time ago, fitted with the BOSS. Following the recommended settings for the factory ammo I started out with I could do 1" groups @ 100 yds as long as my shoulder would hold up. Put up with the comments from those to either side of my bench for a few weekends - and the dust kicked up by the porting - then ordered the un-ported version from Winchester/Browning, about $20.00. Same settings as the holy version, no porting to cause rude comments or adverse effects, still does 1". They won't sell 'em over the counter; you have to call & order them from the factory. Somewhere here some time ago I posted the phone & part number for the stainless piece; do a search for "B.O.S.S." & you should find it.

    I will agree with JustC. I have a Browning in .270 with the BOSS system. I took me several boxes of ammo to find the sweet spot. It consistently shoots sub MOA groups with several different loads. Just remember to record the BOSS settings for each load so you can quickly adjust. Also, make sure that the metal band with the numbers on it is not spinning around on its own. I had that problem with mine, the fix is simple. Screw the BOSS all the way in to the zero on the barrel, slide the numbered band so the zero matches up with the zero on the barrel. Put a few drops of clear nail polish around the band to secure it...

    A friend of mine with more money than brains bought 2 a bolt brownings with the boss on both of them, one was a 30-06 the other a 300 win mag. he is a reloader so he made up some bullets for both rifles and we went to the range, useing the same amo and just adjusting the boss we went from 1 1/2" gropes to 5 shots touching at a 100 yards that was with the 30-06. we never tryed the 300 as it was toooo barell heavy for hunting with. As far as the noise, the shooter does not here it that bad only the people standing around get's the noise and most people will stand around and * rather than move.
    I will never buy a win or a browning as long as they are owned by some other country.

    Rugster,
    Your post listed your shots as,"here & there","couldn't print a
    group".

    That doesn't indicate a BOSS problem, but rather one of the following:
    optics/mounts, ammunition, target & cross hairs clarity, action screws, and or a combination.

    Reasons why ruling out the BOSS initally is, you didn't mention at all that the rifle had performed poorly before, and even if changing ammo it will still print a group relative(large or small) to that load.

    Large or small isn't what you indicated, but that the shots were, "here & there" implies POI deviation for each shot.

    So, the question becomes, what causes the deviation.
    Just one quick example: Was with a customer at the range helping him sight in for a boar hunt. Had Federal Hi Energy (two boxes-different bullets), Remington Premium, PMC Eldorado, and Hornady Standard.

    When shooting the esteemed (in their mind) Federal Hi Energy the shots were all over the place. Examined the ammo found that over one third of the rounds were seated differently. OALengths were so different that on some the cannalure was not showing, on others it was almost out of the neck! Thought some shots sounded different.

    When he tried the other ammo, groups shrunk, and were no longer helter skelter.


    Happy Bullet Holes!

    The initial setting in the book almost never work. Print a 3 shot group then turn the BOSS up one tenth and see if you get a smaller or larger group. If smaller keep turning it up, if larger go the other way. If I am pissing in the wind and you already know this, I apologize.
