I am in no way affiliated with these guys but another member pointed me to Bertram USA. I didn't know there was such a thing. They had 500 Jeffrey in stock as well as 470 and 500NE, 500 weatherby and lots of obscure cartridges it looked like. I was a bit leary, but in bad need of some brass so I pulled the trigger. I received an email from thier sales rep and not too long thereafter I got tracking info. I don't have the brass in hand yet but it shows it is supposed to be here Monday via UPS. So if you need some hard to find brass you may want to check them out. Looks like they just got a shipment in and it may be a while before they get another according to the website.
