Reed's in Oklahoma City http://shop.reedsammo.com/category.sc?categoryId=29 has new brass in both .30R and .32R available. Price is $37.60/100 for .30R and $48.50/100 for .32R. They also have some other odd caliber brass available. Shipping for 100 is about $10.00.
Postscript: I ordered 100 cases from this source, and they arrived today (12/22). They are new and shiny, with the R-P headstamp. Did Remington begin making them again? I was expecting some foreign-made case, maybe like from Prvi Partizan, Igman, etc. and was pleasantly surprised.
