Yes, I thought it was very odd to see 870's have problems. The gun with the extraction issues was very odd. The ammo the student brought would not extract, but someone lent him some shells and those worked. Someone else lent him some shells and those didn't. So something in that gun needs to be replaced ASAP.

Uncle Scotty IS in fact working on a follow up to his book. He also mentioned that having Aimpoints on shotguns is the way to go. He'll soon have his rental and personal guns with Aimpoints.
