...for a Lyman Permacenter All American 20X. I have the scope mounted on my rifle, and want to make initial settings before sighting in. On other Lyman AA Permacenter scopes, the elevation and windage screws are turned counterclockwise until they stop, then turned clockwise four turns. This is the starting point. I found this procedure in a manual for the 10X version, but do not know if this is correct for my 20X. Thanks, everybody!

Standard Op. proceedure is the same for all the Lyman permacenter scopes--I have a 10X on my BSA 12/15 Martini single shot .22lr--Lock and Load!!

Hey, Shipmate! It has been awhile. How is the world treating you? Thanks for the info on the scope. I mounted it on a new Ruger Number 1 in .303 British and will attempt to make little cloverleafed groups with my cast bullet handloads. I needed something new in my retirement to keep from going insane with all the time I have on my hands. Cheers!

I'll drink to that- but i didn't realize Ruger offered the .303 British in their fine No. 1 single shot- what type and grain weight cast bullets will you use- also any dope on powder and primers would be of interest. The .303 is a fine caliber (actually .311" I am told) so it falls between our .30 cal. (.308) and the German 7.9x57mm at .323--I have an older Ruger No. 1 in .22-250 with a 12X Unertl scope- very accurate indeed.

I leveled the scope and did an initial alignment with a borrowed Bushnell bore sighter. I am anxiously awaiting the recession of snow so I can get to my favorite gravel pit for some shooting. I do not know how long Ruger cataloged the .303. I just assumed it was a special run, perhaps by Davidson. Groove diameter, as listed by Ruger, is .311". My handloads consist of a Saeco 305 sized to .312" with a gas check. With the #2 alloy, the weight is 185 grains. My starting load is 24 grains of IMR 3031. This should result in an initial velocity of 1500 FPS, or thereabouts. Indeed, a chronograph is high on my list of 'must haves'. Cheers!
