"We go a step further and use a male threaded 10x 32 stainless steel range rods and and brass female threaded jags.
Is there anybody else who has done the same?"
Blue Smoke, On occasion, when the work hardened brass threaded shank breaks off, I replace it with a 10-32 male thread bolt as well. Having neither a drill press nor lathe makes this a bit dicey, but if I'm careful, I can save the jag. When I buy jags, I always look for a steel rather than brass thread. However, I don't typically fit the jag to the [cleaning] patch. Once in a while, I get one that's a tad oversize, which I then reduce with a file and/or sandpaper.
As for tow + a tow worm, I have the former, and maybe will purchase the latter, but at present a 100% cotton flannel patch on an appropriate jag works for me.
