Duster, your Bulldog looks just like mine! Except I took a dremel to the grips and ground away a lot of material behind the cylinder to clear speedloaders.
I'm working with what I would call non-traditional powders to find good loads for the .44 Spl thanks to the massive powder shortage. So, I've got the Blue Dot loads, plus today I got in an order of IMR 700-X so I put together some loads with 4.5 grains under that same Matt's 250 grain cast HP...use to be this would have been a Bullseye load but I've not had much luck finding that of late, however, if 700-X proves out, a 4.5-4.9 grain charge weight means a LOT of loads per pound, plus it's a fast burner which may yield optimal velocity from the short barrel .44...it may be one of my new favorites!
I'm also going to try some SR-4759 - not a powder normally thought of for the .44 Spl, but there is load data for it. I doubt it will best the 700-X or the Blue Dot for speed from a 2.5" barrel but we shall see.
As soon as I get some chronograph data for the loads I'll post them.
I think the little Bulldog's appeal it that it's not a full-size .44, yet it's not really a super-sub-compact like the J-frames. It's really very similar to what S&W figured out when they came out with a .44 Spl L-frame, except the Bulldog is much more compact. The Bulldog seems suitable to fill a wide variety of roles from deep concealment, to outback, super compact, big-bore blaster. With a good hard cast HP or broad meplat handload the little Bulldog is decent medicine for most social needs.
