I have learned a lot about what's going on in the market place with some of the hoarding and scalping taking place lately... it's maddening but there's little you can do to stop it.
I followed a link to a chat site that literally seems to have thousands of people interacting and notifying the second reloading components or ammo becomes available. They subscribe to availability alerts on every retailer website, get the alert, post it up and instantly everyone starts flooding the sites in a frenzy to but it all up.
I watched (and also tried) as individual notification in the form of links were released for 5,000small pistol primers, LPP, LRP, SRP and the magnums ...... within 2-3 minutes everything was gone. They all then post their "scores" and then proceed to chat about how they don't even need them, reload for most calibers and just horde or sell them. Pictures get posted from guys that have been doing it for months and in some cases you see stacked boxes of 100,000 primers on a table with jugs of powders and projectiles.
It's their money to spend and their pretty savvy about it, but this truly makes it worse for everyone, short term and long term.
