Above are a few of the most popular caliber / load combinations. The enclosed Ballistics CD contains
approximately 1000 caliber and load combinations. Simply load the CD into your computer CD drive
and follow the instructions on your screen. This complete list can also be found on Bushnell’s website
(www.bushnell.com).
After you have determined which ballistic group corresponds to your caliber and load, select this ballistic
group (See MENU SETUP above).
The internal formula will determine amount of bullet drop / holdover in inches or centimeters based upon
distance, angle, and ballistics of your caliber and load.
NOTE: All bullet drop / holdover data assumes the rifle has been sighted in at 100 yards.
This state-of-the-art digital technology allows the hunter or shooter to know precisely where to hold for an
effective shot. This information should be treated as a helpful guide or tool and in no way should it ever
replace practice and familiarity with your rifle, cartridge and load. We encourage practice shooting at
different ranges so you know how your rifle, cartridge and load will perform under various conditions.
Always know what is behind your bullet; if you don’t know, don’t take the shot.
EXAMPLE
You have a 300 WSM and are shooting the following Winchester brand load: 180 gr. Ballistic Silver
Tip bullet at 3010 FPS muzzle velocity. This combination falls under Ballistic Group “F”. After setting the
rangefinder to ballistic group “F”, go to the range and sight in your riflescope at 100 yards. If you then
take a shot at a target at 317 yds, the bullet drop will be 9 inches. If the shot is at angle of 27 degrees
upward, then the corrected bullet drop will be 8 inches.
What if your caliber is not listed?
While we have
taken great care to include as many calibers and brand names in our ballistics tables,
new loads are always being developed. In addition, some shooters load their own ammunition with
unique ballistic characteristics. If you cannot find your load in our ballistic tables, you can still use the
bullet drop feature of the laser rangefinder. As above, sight in your rifle at 100 yds. Then shoot the rifle,
without adjusting the riflescope, at 300 yds. Measure the bullet drop from the point of aim. Using this
drop, select the ballistic group from below. If you will be shooting longer distances then you may want
to check the bullet drop at 500 yds. Because there is enormous variation in rifle barrels, chambers, and
hand loads, you should thoroughly test the ballistic setting before actual hunting. You may need to move
up or down one group depending upon your tests.
