Very nice. Very smooth. Definitely deserving of macro photographs.
Also, you have an understanding gunsmith. Very nice.

those nipples look good they look really good. However i thought they were supposed to be slightly belled at the end to give a good tight fit. Can someone correct me if im wrong.

'Slightly belled' is why caps DON'T fit. The sides should be smooth and slightly tapered
Measurement Results
Big surprise here - not the results I expected.
I measured inside diameter at the lip and overall length (height?) of each of 20 CCI No. 10, CCI No. 11 and Remington No. 11 percussion caps. I couldn't find my Remington No. 10 caps.
The CCI No. 10's averaged 0.158 in diameter and 0.162 in height; the spread was between 0.157 and 0.158 in diameter, and the heights were all 0.162.
The CCI No. 11's averaged 0.162 in diameter and 0.162 in height; the spread was between 0.162 and 0.163 in diameter and again, the heights were all 0.162.
The Remington No. 11's averaged 0.162 in diameter and 0.147 in height; the spread was between 0.162 and 0.164 in diameter and between 0.145 and 0.149 in height.
So, the CCI and Remington No. 11 caps are the same diameter on average, although the variance in size is greater for the Remingtons. That is a surprise, as I had the impression from range reports that the Remingtons were a bit smaller in diameter; they seem to fit where CCI No. 11's were too large and CCI No. 10's were too small.
The difference in height may explain why the Remingtons seem to fit better on the in-between size nipples. They may seat on the nipple sooner than the taller CCI's and thus appear to fit better.

I use a short piece of soft dowel (pine) with a hole bored in one end to hold the cap to about 1/3 to 1/2 its (the cap's) length. With that end, I place the cap over the nipple, then use the plain end of the dowel to seat the cap fully. This allows the drilled end to last longer before the hole wears loose. Eventually, I have to trim the drilled end and re-drill a clean hole. Using a soft wood makes me feel safer about accidentally popping a cap.
No more fumbling and dropping caps.

Mr Mykeal that is good stuff you posted. I am going to buy a tin of Remington
11's and see how they do on the '51. One thing I noticed on both the '58 and '51 is after a few cylinders of shooting the nipples get gunked up some and the smaller caps become harder to get on.
I made a working model of my cap setter this morning. I used a piece of tubing that is about 1/4 inch across. Luckily enough a cap sits inside the tubing just perfect. Holds it tight enough to stay put just fine. I had a piece of metal wire that fits perfectly inside the tubing. (I believe this wire is from a chain link fence. It is what would be wrapped on the link and over the post to another link to hold the fence to the post.) It was long enough to stick out on the end a few inches and easily acts as a plunger. I will know more the next time I get a chance to shoot. But it will eject a cap out of the tubing just fine. I am still looking for a dowl stick though. Not sure if I can find one 1/8th inch thick or not. But I would rather use wood than this hard wire. Hopefully, maybe tomorrow if not then this Friday or Saturday I will give it a live fire test. I think it will work well. When I know it works I will post a pic.
Gotta write it up and send it to the patent office too, LOL

Great idea on resizing nipples - I never thought of that, but I'm going to try it. I bought a bunch of nipples on clearance that are just a little too big for CCI #11 caps, which is what I have available locally. About 50% of the time it takes a double strike to set them off.

I have resized the ones on my 1851 Pietta navy. The nipples were too big for 10's and too small for 11's. I took them and resized them to fit 10's.
