Using .440 rounb ball on deer would certainly be challenging. Certainly would be up close and personal. The ball loses velocity quickly and since they are light in weight compared to.most .45 sized projectiles, shot placement is key. If it will shoot a Maxi-Ball you might be in better shape.
Below are some pretty common loads for the 45 cal and 50 cal Hawken. Do not let the ft.lbs data lead you into a false sense of security about your 50 cal over the .45 cal. While the .50 cal data would certainly give the impression that it has some sort of magical knock down power on deer this is simply not the case. What it does is have more driving power and better penetration when it comes to LARGE game or tough game such as elk or bear. Dealing with white tails (even big ones) they are fairly thin skin and provided you get a proper shot on them and don't try and get fancy with your shot or take a shot that is outside the range of the ML,,the .45 can certainly do the trick.
