I finally got around to slugging the barrel on my Ruger SR1911 and it slugged to .452. I eventually want to order a 452-200 HP 4 cavity mold from MP molds for this caliber. The one I was thinking to get is currently sold out and it’s the” No lube Groove “ because I’ll be powder coating. So the question I have is what size should I get when it does become available? Should I go .002 over the slugged sized, or maybe just .001 over, or just stick with the .452? I can purchase whatever sizing kit I need from Lee here in Canada. Here’s the link……
