Now I think of it, that same ammo was there three months ago.
Creedmore was the cartridge that all the gun writers were promoting last year as the future of the AR platform. The army was considering converting to it yada yada. Similar buzz for .300 Blackout. All of the YouTubes of guys showing off their Creedmore and Blackout ARs.
Rifles in 6.5mm Creedmore is about all that has been available around my area. They must have been really cranking those out. I’ve been trying to get my hands on 30.06 for a gift in a few months but didn’t find what I want yet.
