He's not alone, ignoring advice from those who know better. Don't know too many that shoot, (outside of my club members)
but have a few friends that own pistols (some fairly new gun purchasers) that I forwarded some good ammo sales / info to, before the shortage started.
I encouraged them saying, "you don't find ammo priced this low very often" .. suggesting the stock up.
My advice was ignored. After prices started escalating, same person(s) contact me, wanting to know where to find cheap ammo.
I forwarded a link to ammoseek.com , just to let them get an idea of current prices. That is, If they can find any for sale.
I've also had to tell people that know I hand load, "No I can't sell you my reloads", citing the legal & safety issues involved.
They really didn't want to hear that.. I'd think they'd learn from the experience, but not holding my breath on that.
