CCI's web site shows at 100 yards the difference in 32 gr Stingers and 40 gr. Mini-Mags, The stinger is 68 FPS faster with about 9 ft lbs less energy.
Personal experience tells me Stingers are more effective over all on small critters, and I have no idea about hogs.
At shorter ranges where a Stinger will still expand, yes they are more effective on small critters. At 100 yards it isn't going to make much difference as neither will expand.
