Go with the 30-30 using a soft point like Remington Core-loks. Granted I've killed hogs with a 22lr up to a 300winmag. The 30Carbine may work just fine but I prefer now that I'm older a little more take down energy. My go to right now is my 629 Smith .44mag as backup to my Henry Golden Boy .44mag. Be safe and enjoy. If you think a hog is dead, take another shot to make sure. I killed a sow a couple months ago with my .308 (thought I did). Eyes were open, no breathing, kicked her in the rump one time no movement. I grabbed her back legs and she woke up quick, fast, and in a hurry to get out of dodge. I was able to hold on with one hand pulled out my GP100 and shot her in the head.
