I was talking to an out of state friend yesterday about shotshell reloading. I haven't loaded slugs yet but this seemed questionable.
He's making mini-slugs by lubing/PC'ing his Lee Drive Key slugs and then stacking the slug on a gas seal and nitro card(s) then roll crimping.
Am I being overly concerned about my friend or is this a valid way to go about it.
As I said, my apologies for the probably stupid question but I have VERY limited experience with reloading shotshells.
