Doe's the barrel lug meet the lower frame firm with no gap? you may need a thinner shim. What is the barrel/cylinder gap? You really need a set of feeler gauges to properly determine the gap. Feeler gauges can bought at any auto parts place and most hardware stores. I would try some small...

Rather have one that goes boom instead of rolling, guess you could tape the pistol to the top bar and have the best of both worlds

I am very familiar with ASM stuff so the loose arbor doesn't surprise me. I also do repairs and tuning on these type revolvers. PM me if you would like to have them gone through and fixed.

I ran across a loading method that guys were using in competition with C&B revolvers. They were dropping the loading lever into an empty chamber and noting how far it went into the chamber. This was used as the top of the powder charge in the chamber. A cardboard wad was loaded over the powder...

There are differences in the synthetic greases, some are intended for really cold temperatures and don't work well at higher temps. Mike likes Mobile one, so do I. If I could afford it I would use Aeroshell 22 as it's both hi temp and hi pressure use.

I have used Pyrodex,777, and black powder in my ROAs. T-7 doesn't like a lot of compression. Just enough to seat the ball/bullet firm. If you really want it to bark try it with 4f. It will surprise you.

You most definitely need to check the arbor length. The wedge needs to seat firmly. Other things that help are addition of a cap post and action shield. Once the arbor is properly seating the barrel/cylinder gap can be set around.002 to .004. This will keep the fouling going down the barrel...

Be sure to fix the arbors on those guys, you don't want them becoming paper weights.

That's quite a write up, thanks for posting it. It doesn't really explain the poor fit and finish of the internal parts. I don't think Colt was too concerned about these being shooters rather than collectors items. You would think they would have paid more attention to the letter Bad Karma...

About the only other option if you can't find a cylinder for it is to set the barrel back. It may not be worth the effort.

Can you clarify that? Colt had a paper on chamfering the chamber mouths to direct any gases from firing away from the other chambers. Lubing the ball after loading serves a dual purpose, keep the fouling to a minimum and keep the chainfires under control. Of course any lube at the front of the...

The 2nd gens from my understanding are Italian parts sent to the US under contract from Colt. The parts are then put together and marketed as Colt products. My experience with them is the outsides are pretty and well finished. The internals are a whole other story. These 2nd gens really need a...

I like a 452 200 grn semi wadcutter in my ROAs. Both shoot to point of aim at 50 yards. To make the bullet work I roll it between a pair of crosscut files. This knurls the bullet making it slightly larger. They are a good fit in ROA chambers which are factory size at .453. As far as undersized...

It's most likely from Spain. I have had several CVA branded guns, judging by the Manton style lock Spain is a good guess. It may be marked on the bottom of the barrel. Have you removed the barrel?

Well you posted a rather silly opinion on that one. My main comment was on the original design and the fact that it wasn't particularly robust.

That is a wise choice, Much more solid and reliable design.

I would be happy to look at for you. If I can't fix it you don't get charged. PM me if interested.

Does that apply to the folks that relied on them for feeding themselves and families and defense as well?

I just finished working on a Pietta Paterson. Corrected the short arbor, made a music wire spring for that goofy folding trigger, tuned the hammer spring. It took two men and a boy plus a hydraulic jack to cock the hammer. Also thinned the left bolt leg as it was thick and clunky. There is not...

That full cock notch has about twice as much material as it needs. If you fool with it go slow and don't change the angle of the trigger sear and full cock notch. Lots of assembly and disassembly is in your future. One thing to have is a mainspring vice. Track of the Wolf usually has them.
