Hi Klawman
I've been an NSCA shotgun instructor for 10 years now. I have seen it all and have the pics to prove it. Students can't beleive what they doing, unless they see it from my end of the gun, UNLOADED, of course.
Spend the $50 for a "certified" not "qualified" instructor and you will be thanking me.
You can find them for your area at

Shoot well!
