Finding older .32-20 revolvers with a ring in the bore is not uncommon.
I have read about that (probably here, where I have learned a great deal over the last three years), so I paid close attention to the bore. The bore, and overall mechanical condition is very, very, good. 5 chambers lock up tight as a drum, and one has just a tiny amount of play.
My Speer #13 has one load for "revolver at standard pressures" using a 98 Gr RCBS cast bullet. It is said to have a minimum of 12,000 c.u.p. while staying under of 16,000 c.u.p..
It also has "Contender only" loads which are obviously not intended for revolvers. It comes with a waring about using those loads "in any other firearm".
I have also been researching and reading articles on loading 32-20 to refresh my memory and hopefully learn new things.
I have some 90 Gr Hornady bullets left over that I will be using. I also still have my 32-20 dies. Later I may tinker with a load for a 90 Gr plated bullet as well. Yes, I'll be very careful. I certainly do not wish to damage this really cool old revolver.
Thanks for your insight. Please feel free to add any more useful tidbits. Thanks, AC
