Gerry/linekin, that is exactly the info I needed.Tony,
Plinkerforlife is correct, and the Pro-shot rod does not vary more than .0005+or-. I f you're making a 2 piece rod guide, .190 reamer works perfectly for an aluminum insert. I also make delrin inserts for coated rods, and they vary a lot....Dewey .22 caliber is .195 to .210. the Boretech varies a lot as well. I really like the Pro-shot rods, but he's right about the length as well. They need to make a 40 or 42.

Some years back someone made some Delrin rod extensions to fix the shortness problem. I'm sure I have one somewhere I've just got to find it.
