Attended the Rodney Gun Show (Ontario) on Sunday. Learned from one of the vendors that a different vendor went around before the show opened, bought all of the Large Rifle Primers that any vendor had for sale, and then was selling them himself for $35 per 100.
I understand supply and demand, and willing buyer / willing seller.
Buddy and I said we should pay the $10 for a table, show up early, buy all the stuff we want before the show opens, and leave without setting up our own table. $10 to get early access to all the "stuff" seems like an unethical life hack.
One vendor who owns a gun store said that he's skeptical that he will be able to get Large Rifle primers this year. He was selling old stock CCI Small Pistol and Large Pistol Primers for $80/1000 which I didn't think was unreasonable. He didn't have any Small Rifle (and he sold his Large Rifle to that vendor who bought them all up).
