I thoroughly enjoy loading my own hunting ammunition for deer, antelope, elk, bear, coyotes and varmints as well.
Mostly I load for 6mm Remington, 25-06, 7mm Rem Mag, 30-30, 308, 30-06, 375 H&H & 45-70. Haven't used the 375 on deer yet, only bear. I have used those other cartridges for deer hunting.
Someone else stated that it was like catching a fish on a fly they'd tied themselves. Yes it does. At times I've also made my own bowstrings and arrows. There's a certain satisfaction in all that.
Regards, Guy
