i used to have a 7BR case forming die set, when we had to make our own from remingtons brass (ubr). worked great but i sold it many years ago. i just found a bunch(23) of brass i had formed from old 30/06 brass with large primer pockets....just to play with, and i had not completed the forming/reaming process. so, im looking to buy or rent a reamer to finish the job.
