Carbon ring removal...my way

[lpreddick]

Solvents alone don't remove my carbon ring. Spinning (B&D variable speed drill) an aluminum cleaning rod and nylon brush with JB and occ a bronze one will remove the ring nicely (Hawkeye verified) , but guessing how far to insert the cleaning rod bothers me as I don't like the idea of a spinning brush with JB in my bore. If I had a stop in the bore that allowed the brush to touch it and have it's bristles right at the ring, I would feel safer. I'v done this by chambering a modified case with Sinclairs chamber length guage, then inserting a dowel from the muzzle to touch the end of the guage. Remove the dowel the length of the non bristle part of the brush and mark it and adding a device to prevent the dowel from going into the bore. I rest the end of the dowel against something to prevent it moving out of the bore, remove the modified case, then insert the rod and brush and spin as long as needed knowing the brush is not touching the bore. The dowel can be cut flush with the barrel and held securely with a tight muzzle protector. The photos demonstrate the idea.

I've started doing the same only spinning by hand on a pistol rod. works great as verified
by borescope. Tony Boyer wrote about this method in his book. But what does he know

I read here sometime back that some use their reamer.

Tony Boyer is a god. I doubt I'll ever get to meet him. I've been reading about him for 40-50 years. He was really just a contender in those days but won often (long gone precision shooting magazine) truly in my opinion a golden era in the Benchrest sport. I never was able to get into it but I did follow it back then, as I was putting in 80-100 hrs a week trying to make us a nestegg. (And I miss the magazine especialy Dick Wright, they were great and M.L. Mcphereson was good too. I Liked him but he wasn't quite as charismatic as some. Hell they were all good.
Hate that our young people will never have the atvantage of reading those guys.
