RE: looking for brass
Seems there's a shortage in the States too, from what I've seen on several other sites.
I sold my brass a while back to a guy in the same boat as you, and he was tickled to get it.
Specific brass is not made every day, 365. They'll do a run of 300 RUM production for a while then change outmachinery to run another chambering. RUM's are not everyone's choice so what is made issomewhat limited regardingthe production quantity, and is made in a short amount of time.
When they decide to get back around to making more, there will be some somewhere...you'll just have to snag it if you can.
Hopefullythey will be clued in on the shortage and make up for it.
