Vintage scopes are just as varied and unique as scopes are nowadays - including the mounting solutions. To try to simplify these scopes and show the compatibility of parts, I've divided this Post into four sections: Tubes, Blocks, Front Rings, Rear Rings. The section on Front Rings will also include information on recoil sliding.
In 1968, the 9th Infantry Division in the US Army officially began their Sniper Training and Employment. During the last two days of the course, recruits were to complete the qualification firing.
We decided to try our own version of this ART qualification. To make things interesting, we put the M1000-PRO against our PentaLux TAC-VF 4-20X50 FFP scope. Additionally, we added a shot timer for induced stress.
We are checking our DOPE out to 600 yards with the Winchester High Wall in .45-70 and our Malcolm 6X Two Tone Rifle Telescope. For those interested, we were shooting a 405 gr .45-70 caliber bullet at around 1330FPS.
The Frame Aim Shoot Technique maximizes the capabilities of the Leatherwood ART scopes, allowing you to compensate for bullet drop without needing to know the distance to the target, dial any clicks or use holdovers.
Jim Leatherwood developed theART scopesduring the 60's to solve the important problem of range estimation. In Automatic Mode, the ART scopes can range targets of known dimension and compensate for the bullet's trajectory in one action. But, what if you wanted to increase the magnification more than what was given by Automatic mode?
