DJUSTMENTS

If you desire to obtain even tighter groupings, turn the

micro-adjustable locknut 1/4 of a turn clockwise from the

“sweet spot,” and fire your rifle at your target. If groups

open up, turn the locknut counterclockwise and shoot at

different 1/4 turn settings until you are satisfied with your

groupings. Again, “sweet spots” may vary between rifles of

identical specifications with a given ammunition. As in

any sighting-in process, best results are obtained through
trial and error. You may need to retune the BOSS should

you decide to shoot different brands, lots and types of

ammunition.
Be sure to keep a record of your rifle’s “sweet spots,” especially
if you use your rifle for different game and shoot different loads.

CAUTION: WHEN ADJUSTING THE SWEET

SPOT NEVER SET THE BOSS BEYOND THE

10 SETTING ON THE BARREL.

With the BOSS set beyond 10, the BOSS could become

loose, misaligned or fall off when firing the rifle. This

could result in serious injury to yourself or others.

IMPORTANT:

Each time you set the “sweet spot,” the

body of the BOSS must be tight against the micro-
adjustable locknut. Failure to keep the components tight-

ly locked will adversely affect accuracy. NOTE: The
action mounting screws on your Model 70 should be fully

tightened (See Figure 7). If the screws are loose, tighten
the front screw first, then the rear trigger guard screw.

Always leave the middle screw “snug, hand tight” only.
