FrankenMauser posted about the Starline .327 Federal brass in our .327 handloading thread in the H&R area.
I have a theory -- it was driven entirely by Buffalo Bore, who debuted .327 Federal earlier this year. I'm betting that Buffalo Bore went to Starline and asked them to produce it, and the order was big enough to finally push those guys to make the brass.
Buffalo Bore has used Starline brass in the past...though the tiny picture on the Buffalo Bore site shows a Federal case.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
