M ORE P RECISE A 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.
CARE O F YOUR BOSS-EQUIPPED MODEL 70.
The BOSS is a precision instrument.
