Hi Nate!

I own 3 Dewey rods and when I got a muzzleloader, I just ordered a black powder adaptor from Dewey for the .27 and up cal. Dewey rod. It lets you convert a standard rod into a black powder rod since the accessory threads on the two are different. I've had my Dewey rods for about 10 years or so and they are the best out there IMO. Good luck!
