Went to my favourite LGS yesterday. They generally have reloading supplies and components that they pick up from gun shops that have gone out of business, and mark them down at a good price. So, there's this cannister of Winchester 450 LS there. Never heard of it, but the label is marked for target shotshell loads, so I figure it's gotta be useable for handgun loads. Get it home and start my research. Double-base ball powder that came out in the early 60's and was available until the early 70's. Was replaced by 452AA in the 70's, which was eventually replaced by WST. Dug out my Speer #8 reloading manual from 1970, and there is load data for the .38 Special and .45 ACP, but nothing else. That's fine, as that's what I intend to use it for. The one thing I found strange was that the Speer #8 manual specified using magnum primers with it, even with the light .38 wadcutter loads. So, I have to surmise that it's a bit hard to light up. Any of you 'ol timers got any other info or favourite loads using it? Thanks in advance for your reply.
