Does anyone make a 20 caliber arbor? I called Bushnell, Simmons, B- Square, no luck!

    it isn't all that hard to make one yourself. since i have a lathe (a drill press would work w/flat file going slow) )i turned down a brass rod so that i would have one for my .204 ruger and also i made one for a .17 . on one end i cut a groove (with a foredom, you could use a dremel w/cutoff wheel if you don't have a foredom) inserted a short piece of spring steel piano wire w/slight bend/hump and crimped it in. on the other end i just cut out a slight flat spot with a file for my culminator clamp screw to fit into. spent apx. an hour for both. larry b.

    I had the same problem you are having. I now boresite with a small flashlight in a dark room. If you are boresiting a bolt action rifle go to a dark room take the bolt out place the small flashlight where the bolt would be it will shine on the wall move the scope to where the light is on the wall this will definitely get you on paper.
