I'll bet that Mountain Gun's a handfull with that load. Sounds like fun. How is your gun holding up to this load?My Speer manual lists 12.9 as a max load with a velocity at about 1050.
.JohnK said:NITRO where did Taurus say their medium frame 45 Colt is rated for +P use? I've heard one or two other people state that as well but have never seen anyone say where they read that, it doesn't say anything about +P on their web site that I could find.
Just out of curiousity could you throw a caliper on your M450 and measure the thickness of the chamber walls both outside and between chambers and post the results?
There is no official "45 Colt +P" pressure rating. I think most people use the Ruger only loads published in most loading manuals as a guide for what a 45 Colt +P round is though so even though there isn't an official standard that is the un-official standard. Beyond that, again in my opinion, many people consider them 45 Colt +P+ rounds for use in 454 Casulls or custom large frame 45 Colts.
