Just kidding, guys!

From the FWIW department, chances are, that any bullet you pick for the .44Mag will do well for whitetails. However, the heavier weight bullets will give you an extra margin of penetration, should the angle not be optimum. A lot of cast bullet shooters will suggest that you ain't really serious, unless you use a bullet with a huge meplat (flat nose), that weighs in excess of 300gr. Well, I'm not gonna say they're wrong... BUT, I will say that for whitetails at 100yd, or less, you'll not likely need any more weight than 240gr. Some like 200gr better. Some even like the 180s. A lighter weight bullet will give you a bit more energy, due to increased velocity, But will also likely give less penetration. Trajectory won't be much of an issue at <100yd. I would advise trying several bullets of 200gr or better. XTPs are a good place to start. Work your loads up, and compare accuracy. Do some expansion testing too. Then go with whatever works the best. By the time you do all the homework, you should be knowledgeable enough about your gun, your abilities, and your chosen load, that you will be ready to hunt. Above all, remember, IT'S FUN!!!........................Bug.
