Browning BOSS

[Byron Quick]

I have a Browning BAR II with the BOSS. Caliber is .300 Win Mag. Does anyone have experience handloading for a BOSS rifle? I am getting sub MOA at 100 yds with factory ammo and am curious about what might be achieved with handloads.

i have a win 338 mag with a boss all i did was load the serria accuracy load and then tune the boss to get 2.875 inches a 500 yards for 5 shot groups.

I had a Browning .22-250 with the BOSS on it. It was great for shooting factory ammo, but was a nightmare for trying to work up reloads. Once I found a "decent" setting that worked with the reloads, I kept it there and varied the powder charges. It just added one too many variables.

I've got a Browning BAR Safari II in .338 win mag. This gun with the boss really likes moderate loads. Once I found a load it liked then I played with the BOSS until I could keep all shots in the black at 440 yards.
