Re: BP substitute loads

Pyrodex & 777 are both OK, again ya just gotta be a cleaning Pyrodex as ya would a ML. American Pioneer is proported to contain magnesium. In muzzle loaders using the funny rectangular/triangular looking American Pioneer "pellets" it looks like the 4th of July when they're fired. You can't get a consistant "crush" on them so this appears to be the excess and it really does look like the old "sparklers" we used as kids. The other major objection to this, and while it doesn't affect us, is the magnesium attacks stainless steel and a lot of the new ML's are made of that.

Another idea just accored to me, kinda off the subject, but what the heck, Swiss black powder, which is a lot closer to true old sporting powder, advises, for ML's, not to use more than one grain per caliber, due to the more agressive burn rate. Being as it's hard to get more than 55 grains of otrher BP in a modern 45-70, I wonder if using this in BP cartridges would come closer to the original 70 grain ballistics. Hum, don't know. Anybody ever try it?
