Excerpt:
At a recent sniper match a fellow competitor and Alabama Police Captain advised me to look at a new scope mount produced by Christopher Self of Selma, Alabama. It was many months before it arrived, but when it did, I was truly amazed at the innovation of this master machinist and rifle enthusiast.
It seems he and other shooters he knew had grown tired of dialing the turrets on their rifles for distance. They wanted a mount with presets for several distances. Mr. Self began working on the problem ... or was it opportunity? Several prototypes later, the mount that found its way to my door is the culmination of many tests by several shooters.
The bottom of the mount is screwed to the rifle, such as my Remington 700, in the normal fashion. The gantry is then put in position under spring tension with the use of a screw and wing nut and then pinned in place.
Precision Come-Ups
Now this is where it gets interesting. The little knob on the left side of the mount can be moved to 10 preset distances, noted by the white and red dots. Any distances can be preset. The Remington 700 I used for this test is a 6mm Remington. I first took it to the range and chronographed the loads I happened to have on hand. With bullet weight, ballistic coefficient, temperature, barometric pressure, and muzzle velocity in tow, I entered the data into my Exbal software.
Very interesting...
