Vast majority of new firearm owners are stating that their purchases (including shotguns) are for home security. Doesn't help understand why every shotshell, deer rifle caliber, etc... are gone from shelves completely.
Watching for shot shell availability is a daily affair if you want to stock up and be ready for the clay season this spring-summer.
I started buy my favorite 12 and 20ga upland loads by the case. Doesn't look so crazy now.
Couple months ago Fleet Farm had trap loads for a $1 off per box. The guy was stocking the end cap and I said "any limit"? He said nope, take them all if you want. I told him fill up my cart. Yes, I'm that guy. However, we do a lot of annie oakley shootouts in the summer, so I want to make sure we have enough. So... I think there is some psychology behind the buying, even me. Now stocking up on Toilet Paper... not happening. Ha ha
