This topic was mentioned in another thread so I thought I would measure the gap on my Spiller & Burr revolver by Pietta.
Useing feeler gauges starting at .006 inserted between barrel end and cylinder face the fit was a little loose and the cylinder turned freely.
At .007, fit seemed just right and again the cylinder turned freely with no discernible drag.
The .008 gauge went in a little tightly and was only able to rotate the cylinder for two chambers before it bound up.
I'm guessing at .007" that's not a bad gap and the cylinder being faced off within .001" +/- that's not too bad.
What do the rest of ya think? :what:

Doesn't sound bad...I'm not very familiar with that gun though.

That sounds like a small gap indeed. Question is how many times can you shoot it before it starts to bind?

I have not found a factory spec for a Remington C&B barrel gap but the Colt spec is .008. I think most articles you read well say .008 is about optimum. Excess gap generally does not cause any problems, a tight gap well. Tighter and fouling well cause the cylinder to drag.

I can't recall to be honest...it's been over 3 years since I've shot it. I do recall the main problem is ruptured caps falling down into the mechanism forcing me to turn the cylinder by hand to get them out. I don't think I have ever shot more than two cylinders before putting it down to shoot my T/C Seneca rifles...mostly because I can't hit a damn thing with the Spiller & Burr! :cuss:

Measured my new 1858 Remington New Army (Navy?) Police .36 caliber. Gap is .006" snugly... .007" would barely go in and the cylinder wouldn't turn at all!
Aggravates me to no end the range was closed down here...no place close by to shoot and it's frustrating me!!! :cuss:

The new Remington cylinder arrived today...it dropped right in and cycled perfectly. Cylinder gap was .007"...just .001" difference than the one it came with!
Cabellas did give me a $40 refund coupon so all in all I got the New Army Police for $239 with 2 cylinders...not a bad deal huh?? (free was my first choice but they politely declined that request) :banghead:
