Range Rods
Dave Kiff at PT&G can fix you up. He made me range rods in 17, 20, 22, 6mm, 6.5mm, 7mm, 30, 33, 35, 37, 40, 41, 44, and 45 calibers. To properly use them you need about 25-50 different bushings for each caliber. If the Range rod cost you $39.00-$69.00 each and the bushings are $11.00 each you are talking a considerable expense. I know that I have over $1,600.00 tied up just in bushings. I use the same bushings on piloted center drills, piloted muzzle facing tools, Piloted crowning counter bores, and chamber reamers. Since I added the selection of pilots to my collection to give me the optimum fit I have not had one problem with reamer chatter.
