I get where P&U are coming from, trying to get newcomers into the SA-thing by means of cheap ammo that is readily available. But...
No. Just...no.
This whole thing could have been circumvented by one simple word. Just one.
"RELOAD"
Can't find .45LC, Schofield, .44WCF, or other hard-to-get carts?
Build your own. Tailor the load to your liking, be it mouse load or dragon, smokeless or black powder. And that's the only "Tayloring" you need to worry about. (Pun intended)
Intimidated? Remember, every time you stoke up your Colt Army, you are "reloading".
And that's all I've got to say about that.
