To All;

I have a friend's Browning .30-06 that has a BOSS system on it that I am going to work up his 'light rifle' loads for our Africa trip. I will be using North Fork 180gr. bullets loaded hot.

Does anyone have any experience with this system and N.F. bullets as far as where I should start on the BOSS adjustments?

I will call Browning and run this by them, but I'm not expecting any help. Does anyone have any contact numbers for them where you have had success obtaining info on this system?

Thanks,

Sam

CHeck Brownings web site, they will give you starting points per bullet wt. and caliber.

Thanks. I already have that down loaded. I was hoping for an easier way out of it than experimenting.

while the FN barrel weight DOES work for accuracy (it's designed for sniperrifle tuning) I, myself, can't see the USE for a ported on on a 30-06.. even if it weighed 5# and was only shooting 220s at 2400s....

But,...

Start it with ANY 180 load, and see. The fact that each gun is a rule unto itself holds very clear here. If one is not aware, the purpose of the boss WEIGHT is to create consitency in the barrel whip as the bullet leaves the barrel. The fact that it increases NOISE to down right painful is a function of it's reduction in recoil.

You can do a binary sort... start in the middle, shoot 5,,, turn it 1/2 the way one way, shoot 5,,, turn it back and then 1/2 the way, shoot 5.... look which one has the best groups, and GO WITH THAT (unless you really want to tune it to the gnats hiney... which is POINTLESS on the bench)

after you have got it shooting POA off the bench, pick it up and shoot it off hand... and see where it goes... adjust the scope (you will have to) and shoot off hand some more...

you might start the offhand shooting at 50, as 100 can be a trick.. if you are using a scope, turn it to it's LOWEST power... believe me

I have bossed three guns, my guns. The BOSS booklet calls for a setting of five "5" for a 180gr Federal bullet. Really, the manufacturer doesn't matter, it is the bullet weight that is most important.

On the range use cardboad backing with multiple bullseye stickers affixed at the 100yd mark. You will want to label each bullseye with the boss setting for that group.
(This will save you time and money by keeping all the data straight) The first bull for your gun will be labeled "5". Fire a two shot group and analyze the group size. If they are not in the same hole or eclipsing on another, tune the boss to "5.2". If the group gets bigger, reverse the setting to "4.8" and continue reducing by ".2" until the holes touch. Then you can adjust by ".1" if you want to get that precise. And believe me, you can get that precise with the boss. If the group you shoot at "5.2" gets smaller, then just follow the aforementioned advice, just add tunrs instead of subtracting turns.

It is very important you use well aimed shots. If the shots in the group didn't "feel good", then redo that setting.

Thanks guys. I haven't worked with this system before and only had the factory ammo info. This will be helpful.

Cheers,

Sam
