Question about Telescopes
I recently bought a Bushnell Custom 3x-7x .22 scope from the 1970's. It has the Bullet Drop Compensating feature. I need a manual. How do I sight this little scope in for elevation? There seems to be no way to raise the elevation separate from the BDC feature...

Hold the outer portion of the elevation knob and unscrew the screw on top. then pull up on the outer portion and you'll see a silver screw marked with an arrow and the word "Up". Sight the rifle at a known distance and then line up the knob with that distance as you push it down on the scope and replace the screw. I have one of these and figured this out on my own, however I'm missing the mount and would like some pictures and dimensions of the mount if any of you can get some. I'm gonna be machining a new one and would like to keep it as close to the original as possible.

It would be nice to know what muzzle velocity the BDC is set for, but I assume it's standard high velocity, not Mini Mags and etc.
The one I have mounted on a Henry lever action has a double sided clamp that fits the groove on the action/receiver and the groove on the scope. Rings won't work due to the groove on the bottom of the scope.
The clamp mounts for lasers, like a BSA that has mounts for .22 grooved receivers and Weaver bases, would probably get your scope functional for $30 or so, and still have the laser that would work with Weaver bases.
