I'm on the iPhone right now so I don't have access to EXACT numbers but from a carbine middle of the road 240g loads will do 1850 FPS + and in the process generate 1800+ ft lbs
That is what 440 Corbon puts out in the 240 grain I shoot in my Desert Eagle 10' barrel...Not sure the 44Mag has that kind of power

Harley was replying to your post where you sated that middle of the road .44 mag performance is 1850fps +. Harley said that that type of performance is what he gets from a 440 Corbon from a 10" barrel and was not sure the .44 mag could that safley that is where the comparison ended.
The only way a .44 mag will get 1850fps with a 240gr bullet is from buying boutique ammo such as BB. Or you handload full house loads with with H110 or similair powders. I've been loading the .44 mag for my carbine since 2005, and can tell you that anything over 1850fps with the over the counter powders available today would be an unsafe load. A max load of H110 with a 240gr bullet may get you close to 1850fps but I doubt it will put you over that safely.
