So, following posts here made me remember some issues I had a while back with my 617 revolver. I purchased my 617 no dash, TT, TH, 6 inch, 6 shot, at a gun show Many years ago. It was very nice, with box and papers, for what I thought was a great price. $375. When I first fired it, I noted that It had terrible blowback/powder/lead, whatever blasting to the sides and in my face. Upon Inspection I noted, I didnt look past the excitement at the gun show.
The Forcing cone was improperly cut, as it looked like the angle was cut off center, left side of bore was sharp with right side having some angle. So Mabey should have sent it in, but chose to repair myself. I ordered the Brownells kit, with the 11 Degree reamer. Kit came with reamer, bronze lap, and cylinder facing cutter, as well as handle, .22 mandrel/rod. Oh, and plug gauge. The plug gauge being a insert to place into the barrel, to verify depth of forcing cone cut. it has 2 steps, a minium and a maxium. similar to using a throat erosion gauge. So I was able to cut the forcing cone to actually have an even angle, altho, to achieve what looked evenly cut, it was at the maxium depth when measured with the plug gauge. Well, what did I have to Lose? So, shooting afterward was Great. problem solved. I did not ever verify accuracy, before/after. It does, like all my Firearms, have abilities beyond mine...
So, Hopefully, I am not too long winded.. But anyone have similar issues with their .22? I was actually thinking that how well the .22 cylinder Reamer Loaner worked, that if the cutter Kit would be useful to members, a similar program should work. I dont have pictures, but there are some you tube videos out there that show this tool in use, and it seems fairly easy to perform. If I can do it with satisfactory results, you all should too.

There are many rimfires and centerfires that need the forcing cone cut or recut to make it right.

If you do decide to loan it out, be aware that the 1st chamber reamer disappeared into neverland. You would need to keep tight controls on who has it (have each person send it back to you to make sure it's still serviceable and all the parts are still there) at any given time. The actual process is simple and easy.
