CALREB: I posted a 'Like' to your photograph of your four PPC revolvers because the option I want to choose, 'I'm jealous', is not available. Nice toys.
NICK B: As stated, wadcutters for the open matches, .38 ball for the distinguished. I did see a number of Colts customized for the open matches. Since they had the usual customizing, I could not tell if the starting point was a Python, or one of the other models. As time passed I also started seeing more Ruger six series (like I had) on the line. But the overwhelmingly predominant revolver was the K frame Smith. I was not paying close enough attention to know if the L frame was supplanting the K frame once it was on the ground. One has to look fairly closely to determine which frame size, and I was just not that curious.
If I look back in my old issues of 'American Handgunner', where they had an annual article listing gunsmiths, just about all of them would work on/build Smiths, Colts and Rugers. You paid your money and you took your choice.
I used a Python for the Distinguished matches, which CA had just started around '83 or '84. My first leg, I shot high enough to get the maximum points, six. Twenty four got the medal, which meant at this pace I would have it in four matches. Unfortunately work responsibilities escalated so quickly I had to drop out of competition, so that great beginning could not take me anywhere.
I had had my L frame customized so that I could shoot the open matches with it, then return it to stock configuration for the distinguished matches. The idea was to use one revolver for both categories of matches.
In lieu of a bull barrel I had Wichita Arms install one of their stainless steel barrel shrouds with integral comp. The shroud was anchored to the barrel via a hex head screw threaded into the front of the barrel underlug. So, barrel shroud on for open matches, off for distinguished. But when I removed the hex head screw, the shroud would not budge. I quickly figured out why.
My L frame is a 586. I had had it electroless nickel plated to achieve the corrosion resistance and reduced finish wear of stainless. But, that process had added just enough additional material to the barrel that the very precisely manufactured shroud fitted too tightly to come off. Thus concluded that brilliant idea.
This project too was concurrent with my work responsibilities increasing, so my L frame never saw the heat of competition. Too bad because it is a very nice revolver.
