RE: What percussion cap?
CCI #11 Magnums are good caps. I never had much problem with them. I personally like the Dynamite Noble 1075 cap and that's what I use. For a while I was forced to use Remington caps. In the past I had some terrible luck with them and just had no faith in them but they seem to have gotten a little better. Still, I will stick to the 1075 german caps.
