It's really not fair to call the all-new generation Leatherwood M-1000 a riflescope. More appropriately, it is an extremely advanced sighting system; the basics of which have now been in constant military use for more than 40 years. Using this system has never been easier, or more user friendly!
All the shooter has to do is place the reticle on the target, zoom in to FRAME an area of known size (i.e. the 18" height of a buck's chest cavity), AIM, and squeeze the trigger to SHOOT. It all takes less than 5 seconds, and the shooter's eye never leaves the scope! When the shooter frames an 18" or 1 meter target using the brackets on the reticle, the scope will automatically range the target and compensate for bullet trajectory for distances of 250 to 1,000 meters. This means no holdover or guesswork.
The CAM System of the 2.5-10x44mm ART (Auto Ranging Trajectory) system, which was invented and designed by Jim Leatherwood for military snipers in Vietnam during the 1960s, has been redesigned for today's sportsperson. By using an incrementally adjustable trajectory cam, the M-1000 can be calibrated for just about any center fire rifle cartridge, from .223 to .50 BMG. Additionally, the new design permits the cam calibration ring and range ring be used or set independently. Easy access locking screws make CAM setup quick and easy.
