Ah yes, round ball revolver loads
Speer used to publish round ball loads for the .44mag, using .433 dia round balls. Sometimes they worked okay, and made a
plunk - whack at the indoor range, plunk for the discharge and whack as it hit the paper a 1/2 second later. Drew lots of curious stares
At one point I had a squib load, in the 6½" S&W .44 I was using. The ball stopped 1/2 way out the muzzle, which at least made it somewhat easier to grab & remove. Also filled the barrel with 1/2 burned Bullseye, which for the record, smells bad
I abandoned that project at that point. I notice Speer doesn't publish the loads any longer, either. It might be fun to revisit it with Trail Boss, Titegroup, or something else position insensitive.
