The bore/muzzle guide is made for my .38/.357 rifle. I'm not sure one could be made to work with a bore as small as a .30, but I haven't tried. I use a short .22 rod with this setup. The main body of the guide is made of 3/4" Delrin with a hole just big enough to let the rod slide through. Then, I made a brass insert for one end, just under bore diameter. The insert has relatively thin walls, the idea being to combine the strength of the brass with the smoothness (and low cost) of the Delrin. A bit hard to describe, but picture a 3/4" diameter Delrin cylinder about 2" long with a .035" OD piece of brass protruding about 1/3" from the end.
