Leica IBS G7 Reticle
The ballistics experts at G7 have teamed up with the optical experts at Leica to develop the Integrated Ballistic System (IBS) reticle. This multi-purpose reticle allows the shooter the advantages of using the ballistic drop reticle or using the center aiming point in conjunction with a custom ballistic turret that has been calibrated in yards. The hold over aiming points give the shooter aim points out to approximately 500 yards depending the on cartridge and bullet used. The reticle has windage hash marks that assist the shooter in compensating for the wind.
The IBS Ballistic Calculator powered by G7 allows the shooter to calculate and print out the distance for each hold over dot or hash mark for his or her rifle and cartridge. The ballistic information of the shooters cartridge is entered into the calculator, or factory cartridge specifications are selected, and allows the user to print a field-carry hold over chart for that specific load.
A custom ballistic turret may be ordered from G7 which allows the shooter to adjust the vertical turret to match the distance to the target, then hold right on to complete the shot. See the downloadable form for ordering your custom turret from G7.
The Leica ER riflescope when equipped with the IBS G7 reticle gives the rifleman or woman the ultimate in long range performance whether using a bullet drop compensating turret or reticle.
