Let me give you a little tip based on my experience with a Ruger NM Vaquero 45 Colt. After you have the cylinder honed, unless it just shoots lights-out, fire-lap the barrel....ALOT. I did and almost gave up after 60 lapping rounds as I saw no noticeable improvement. Exactly 12 more rounds made a huge difference. After the cylinder job and lapping, mine now literally groups better at 50 yds. than it did at 25!

Good luck!

Fire lapping helps accuracy because a lot of the new Rugers have thread choke. I bought two Bisleys recently (a blue 44 FT and a S/S 45 convertible) and both had a pretty bad dose of it. The blue one cleaned up with about 60 - 70 shots. The S/S one is up to about 120 and it is almost gone. It's a PITA to do but required if you have choke and want a good shooter.

Now that you mention it, the hippy-dude over at Gun blast did mention that stainless barrels would take more shots to fire-lap.

Reaming .45 colt chambers is not a mystery, but you simply have to know what you are trying to achieve with what particular bullet. Sometimes the chambers are undersized, so reaming just the throat won't do the whole job. Refer to the chamber specs:
http://www.saami.org/PubResources/CC_Drawings/Pistol/45 Colt.pdf
You can use a throating reamer to do just the throats, or a chamber finish reamer to do the whole chamber. If you are slow, the job might take 30 minutes.

As far as "thread choke" on a .45 Colt barrel, practically 100% of revolvers will demonstrate some bore diameter reduction under the threads, no matter what the caliber. (to a lesser extent on older revolvers with pinned barrels.) I suggest that leading in that area might well be an issue with the forcing cone more so than with the slight bore reduction. Before getting concerned about it, accurate measurements of the bore should be done. The final word is whether the revolver shoots well.

Hi fellas,

Sorry I am late to the party but I am here now. Been doing quite a few Ruger cylinders, the FB page is more or less photos of finished cylinders if you want to see finished work, it's a public page so it should be visible to all.

Not sure if I can reply to a PM or send a PM being I am new on this forum but you can reach me on the FB page or the forum for cast boolits or email to mightbeme04 at that yay hoo dot com place.

You have to be careful with the heavy fire lapping though, you can kill your forcing cone. If you over do it. (Speaking from first hand experience.)

I have seen improvement by taking a bronze brush and then wrapping bronze wool around the brush then running it down the barrel a dozen times....or more
