Cal I can't recall the last time I shot a factory loaded centerfire cartridge. My lists of those I load for are 5.56, .223, .308, .270, 7-08, 30-06, 30-30, 32 win spl, 9mm, 38 spl, 357, 40 S&W, 44 mag, 405 Win and probably one or two others.
Not as long a list as some but long enough. I used to load shotshells too but gave that up when the price of shot went through the roof.

I was seriously thinking about loading the 405s with black powder. But after reading up on it I don't think its worth the hassle. With using a drop tube, filler etc., and then the cleaning afterwards...nah. I can just use my BP rifles for that.
