I have become more and more interested in the combative use of shotguns recently. I plan to take a shotgun course within the next year or two from someone along the lines of Dagga/HiTS or Givens (training budget is blown for this year).
I was wondering if anyone could point me at some good resources in the meantime. Seems like there is a lot of hokey shit out there about shotguns, and not a lot of instructors/resources who have much operational experience with shotguns.
