Gentlemen, here is a thread in the Handloading & Reloading forum discussing .327 at the bench.
http://thefiringline.com/forums/showthread.php?t=402168
Right now, jacketed .312" slugs between 85 and 115 grains do NOT exist in anyone's stock or supply.
I'd love to hear someone that can prove me wrong and provide or PM a link!
Cast bullets or very light (71gr and below) slugs are in stock in most places. This will improve... eventually... but they are scarce right now.
