Bushnell 201966, 201965 manual Example, What if your caliber is not listed?

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.
