.45 Black Powder Magnum

I know this cartridge was uh... "invented" for use in cartridge converted Colt Walkers, but it's also possible to be used in .410 chambered handguns like the Judge, Governor, Bond Arms derringers, etc.

I have many questions, so please bear with me.

1. Is it safe to use Triple 7 or Pyrodex? I'm not one who likes to use fillers, so I would fill the case with either powder and I believe the capacity in the .45 BPM case (yeah, I know it's really a .460) is something well over 50 grains. Is that safe to shoot in a Judge or Governor?

2. What velocities are you getting with BPM? What barrel length you get said velocity? Currently thinking of using this in a 2" Public Defender and 6 inch Judge.

3. Can I load .45 BPM with .45 Colt dies or do I need .454 or .460 dies to load them?

4. Do you think the .45 BPM has enough merit in power and/or accuracy over .45 Colt using smokeless powders? Basically, is it worth getting into for shooting in a .410 revolver?

When we teach our M/L class, one safety point that we cover, is to read and follow the guidelines in their manuals. While we may develope our own "personal " techniques, we teach by the book. We do this to protect the students from danger and us from personal liabilities. ….

Your call but,
Be Safe !!!
