FWIW... until I comitted heresy and installed a 209 primer attachment to my .54, all I ever used from the late 1990s up until last fall was CCI caps. Never had a problem with any going bang.
Didn't "whack the stock" right during loading once in the last days of Oklahoma's late-year antlerless season in 2022 and scattered a group of does with only the sound of the CCI ... I found no powder in the drum. So, since I had 1,000 209s in the safe, I opted for MORE FIRE ... and 209s seem to always work too. Still have quite a few #11 CCI caps, and wouldn't be afraid to use them anywhere...as long as "whack" the stock just right during loading.
