Tight Cylinder

[Conman]

Yesterday afternoon my new to me Bearcat and I stepped out back to test fire.
Three holes the cartridges dropped in and three holes took a push of a finger to load.
What grinding compound would be best to use on the tight cylinder holes??
I have already cleaned them all well with a brass brush in a power drill. Or any other procedure might one of you EXPERTS suggest?

I wouldn't use a power drill with a brass brush, but that's just me.

My Bearcat has tight chambers, but I noticed it most with Remington Golden Bullets. Try switching ammo. You might try polishing compound on a bore mop. It looks like this:

Sorry I didn't cover all details. I tried different brands of ammo. I used a mild compound with a mop. No change. That is why I asked about specific compound to relieve the tightness. OR should I just learn to live with three tight holes??

Flitz applied to a 25 cal mop and run in a drill should do the job well. I don't recommend anything more aggressive, and that worked for the two very tight chambers in a stainless Bearcat I had.

Those would actually be "tight chambers in the cylinder."

Maybe contact DougGuy or 2dogs to see about a PROPER polishing & sizing of the chambers, to avoid the possibility of accidentally making them "egg" shaped.

If it's a new gun, let Ruger fix it under warranty. Otherwise Flitz or Browns bore paste.

my 2 cents. v/r

IT is a 1970 1st version Bearcat. Too much trouble; I'll live with it!

Thanks for input.

Brownells sells a chamber finishing reamer for revolver cylinders. Fifty bucks well spent if you have a bunch of revolvers. Or ship the cylinder to a specialist who can make it right.

thats what I usually do , still have a left over .22 LR Clymer finishing reamer from the shop and will just "chase" any rough or fouled chambers,,,gotta be careful you do NOT over do any abrasive stuff, to oblong the chamber,,,,so unless there is a burr at the mouth of the chamber ,easily enough to deburr,,,you can even take an old 22 cal aluminum rod, cut a slot in the open end and slip on a small piece of fine emery paper, just enough to clean out the chamber, again you do NOT want to be removing material........but to polish it

That's good advice.
I use wooden dowel rod and 2000 grit emery paper In a drill set on slow speed. Then with Flitz on a piece of cloth for a mirror finish. I do this for a tight throat, too.
