Charlie hope you had good luck with your .44 Magnum.
I've been using a .44 magnum on deer since Indiana legalized handguns. At that time, I'd stocked up on 250 grain Winchester premium partition golds. It was a Nosler partition bullet that worked great on deer. For the past 5 years or so I've been using my hand loads, a 240 grain Hornady XTP bullet over 20 grains of 2400 powder. They work very well also.
