Leupold Hunting Equipment - Manual (Page 5)

As an example, a 30-06 with a 180 gr spitzer bullet and 2700 fps muzzle velocity
would require the use of the smaller triangle mark. A 30-06 with a 150 gr
spitzer bullet at 3000 fps muzzle velocity would use the larger triangle mark.
We have designated three sets of cartridges to be used in conjunction with
the large and small triangles and sight-in distances of either 200 or 300 yards,
described as Group A, Group B, and Group C:
• Group A cartridges will use the large triangle and a 200 yard zero
• Group B cartridges will use the small triangle and a 200 yard zero
• Group C cartridges will use the large triangle and a 300 yard zero
Be sure to verify the aiming points by practicing at the actual distances at
which the points are intended to work. Ballistics performance of your rifle
and cartridge can vary somewhat from ammunition manufacturer data
due to rifle barrel length, actual ammunition performance, and various
atmospheric conditions.
