Greetings My Good Tater
In the bad old days of my callow youth, I used CCI primers exclusively in everything, small and large, rifle, pistol, and shotgun. I even favored CCI percusion caps over any others. Good stuff, never a problem.
Now as I enter my third century more senior years I pretty much use whatever I can get. You know what? As long as I am not doing that long range 1/4 inch group shooting it doesn’t seem to matter, they all go bang and I almost always hit the side of the barn.
Hope this helps
Prof Marvel
