First off,, ,what are you using now?
What kind of accuracy are you getting?
Accuracy should rule in ANY ammo used in hunting, accompanied by bullet placement.
I've been handgun hunting for over 35 years for big game, and even longer for small game. Here is what I'd suggest for a cast bullet.
Match the bullet diameter to the bore. (You have slugged the barrel, right?)
Next, load a bullet of the proper diameter, of a hard enough material to not lead when fired at normal velocities, that will be the most accurate load you can assemble & match to the gun.
In general, a cast bullet, of that caliber,,, moving from about 900 fps to 1200 fps will be the best option, and will reliably anchor a deer anywhere in North America. (As well as many larger critters too.)
In general, pure lead will not be the best choice,, even with a GC.
And velocity will not be the best choice over accuracy.
BTW; As a Hunter Safety Instructor,, I teach ethics in my classes. An animal deserves an ethical clean kill. Poor accuracy, poor bullet selection, can translate into a wounded animal. Do you want to gamble on a deer of a lifetime,, or even one necessary to feed the family with poor choices?
(BTW; Last year,, I made a mercy kill of a poorly shot 7 pt buck, that someone else made a bad choice of their decisions. He was gut shot 1-2 days prior to my killing him, with part of his guts exposed.)
Look at the above responses as to an alloy choice.
