Previous: How to: K+M Tapered Reamer Case Mouth Chamfer Tools About The Author Roger Miller 2 Comments Michael Taylor says: 12/17/2020 at 7:16 pm I did not watch the video as I understood how the vernier worked. But if I had, I would have noticed that the anvil has a ball on the end. The video does not indicate the ball diameter. However, some reloaders might want to know that this ball is larger than 0.172″, the inside diameter of a 17 caliber cartridge. The bottom line is, the tool works with calibers down to 20 cal (.204).

We’ve added the following note on the product page: works with .20 cal and larger (Anvil ball diameter: 0.185″). Log in to Reply Leave a Reply Cancel replyYou must be logged in to post a comment.
