thanks, again to all for the info and experience. I notice that Dixie has the fixed choke versions for a reasonable price; I'll look at Navy Arms, too. I've used several cylinder bore shotguns in the past and am accustomed to "regulating" the patterning by fooling with shot hardness and size, so cylinder guns don't scare me (much).
One issue we have with black powder here in SoCal is fire. I'm especially sensitive to this since I stand fire watch as a volunteer when we are in Red Alert weather, which is increasingly often. Do black powder doubles send any more flaming debris out the muzzle than ctg. guns? Might limit where and when one can shoot the front stuffer (although almost all areas including outdoor ranges are closed during Red Alerts anyway--which truly sucks since it even happens during quail season now).
