I agree, most any NON HP heavy for caliber bullet will work just fine.
I like the XTP's either 158 FP or 180HP, the Speer 170 Gold Dot SP and the Hornady 180 SSP... A good cast 180 or 200 would likely work well too.
I haven't shot any hogs, but lots of deer with these bullets. So far the 45Colt, 7x30 Waters, 12Ga and a 30-06 is what I have used on hogs. I would not hesitate for a second to use a maxi on the biggest of them!
