Was at the range today for a class. Ended up sitting next one of the owners of one of the largest LGSs in the area. Ammo was a hot topic of conversation. He has contacts at the major ammo makers. He said that certain calibers are just not being made. Classic calibers, 30/30 Win, 30.06, .38spl. .357mag. etc. are not high on the list for production. Only 2 days per month are dedicated to the production of such calibers. Just blows my mind. He gets a few cases and they are gone in 2 days. But he has 9mm, .223/5.56, 308 by the pallet. Did not ask about prices. If you are looking for such calibers, call the stores often and be ready to jump in the truck with some $$$$.
