One of the things I did when CCI changed from 6 to 4 wing is to test the caps.
I was talking to CCI and one of the guys that heads up the Cap line at the NRA show a few years back..
He would not tell me that they change but kept telling me they were made the same other then 4 vs 6 wing.
To shorten the story I ask him if he wanted to come to my place to do some testing and he said no but said he would send me a tube for free to test.
I use a crono and a few other tests on loads..
The test that told the real difference was a very easy barrel PSI test in a way.
I used a wood rod, and would angle the gun in a mount so the rod would move but not shoot out the end of the barrel on any caps.
I tried several caps with the test and what I found on a clean barrel, the rod would move free every time in the bore for the test.
The 6 wing caps on the gun in a vise would move the rod about 6-8" more then the 4 wing caps every time. Tested 4 then 6 then 4 then 6 so the gun would have the same use for every test.
After calling the guy back and talking to him, they said that they have a way to measure PSI on a section of barrel like they do any other round, and that my rod test was in fact correct showing the primming to be better on the 6 then the 4.
He added that if it caused a problem with the live fire guys they still have the compound mixture and could change back.
Sales and time would tell.....
So that was what I found.
I also found some of the German 4 wing to be lighter then the CCI 6 wing.
Early german in the tins were hotter.
I use the wingless now but still have some 6 wing left that I save for my sharps.
I have enought to go a few more years then I will need to start looking and testing to see what is out there.
Just my 2 cents.
BTW, that type of test using the wood, comes from a old timers test to see if the hammer is hitting the firing pin on a gun good.
You could stick a piece of wood in a gun like a german K98 and see if it shot it out, if it did then the spring was good to go and the FP was intact. As it was common to cut the FP on a lot of bring back war guns.
So I said why not for a BP gun and caps.
Use a 1/2 wood dowel ( or size to fit the gun), good to test. Drill and add weigth if needed for shorter gun. Just make a mark so it is 1/2" to 1" in front of the flash hole.
