For hand loads or any other unique loads not shown in the above list, the table on
the next page provides a guideline for selecting the appropriate TBR performance
group. Check the ballistic performance of your bullet by consulting your reloading
manual, ballistics software, or by referring to literature or Web sites provided by
your cartridge manufacturer. You may also visit the Leupold Web site at
www.leupold.com for more assistance in selecting your group. If you have your
ballistics performance data, select your performance group from the table on the
next page based on the bullet path at 500 yards. Be sure not to confuse bullet path
with bullet drop. Bullet path will be related back to your sight-in range whereas
bullet drop relates only to the total drop of the bullet, regardless of sight-in range.
