I cant speak for the world in terms of ammo and gun hoarding, but its still hard to get 209 primers, some powders like Unique and Clays are still hard to find, and shot is still around $29.00 per bag here which is around $10.00 too high in my opinion.
I think the guns we like will eventually lose value as I dont know of anyone much younger than me (turn 46 next month) who cares about them. The young folks I know who like guns at all seem to be into either pistols or EBR's (evil black rifles). I cant say as to whether they will eventually discover vintage doubles, or will stay in the action adventure Walter Mitty mindset. If their interest dont change/expand, as our numbers die off, there will be less and less interested buyers for our musty dust and hopefully not rusty hoards.
