I had a Browning BAR MkII Safari in .30/06 with BOSS (Ballistic Optimized Shooting System).
Once I had it dialed in to the different ammo types I used, it worked great. It is a good way to dial in your groups.
Here's a link to Browning's recommended starting point for tuning your BOSS to your ammo type.
"To preserve liberty, it is essential that the whole body of the people always possess arms, and be taught alike, especially when young, how to use them." -Richard Henry Lee, Virginia delegate to the Continental Congress, initiator of the Declaration of Independence, and member of the first Senate, which passed the Bill of Rights.
