At 25 yards with a Special load, you're out to have fun - not go on some Chuck Yeager-esque quest to push the outer edge of some envelope.
And I'm here to tell you, you can have a ridiculous amount of fun with a 250+ grain .44 lobbed out around 700-750 fps.
What I hope to be my Final Solution to the .44 Boolit Problem:
I wanted the basic concept of Veral Smith's 250 grain LFN, but with the simplicity of tumble lubing, so I worked with Tom at Accurate Molds to come up with this one. Nose length was calculated to work in S&W's and Rugers (plenty of room in the Redhawks), but may well be too long for the "book" COAL that most carbines seem to need.
That nose will get you a little more blunt force trauma on a milk jug or soup can than a Keith (which does not suck in that department), but should fly better (if longer distance becomes your intentions) than the super-blunt WFN's.
If you do intend to gas things up, this general style puts more of the overall mass out in front of the case, which will give you more room for a bigger charge of the "boomer" powders like H110.
