RE: Queston for you guys......
First as to my ego all I did was copy and paste from wikopedia. I do not know all those cartridges. You are correct on the hearing and a lot of people never get to see the hog because they were making noise. I will still defend my position on their eyesight being better than people think. They cue on movement very well. Granted I have stood still and had hogs walk within ten feet of me but then they winded me and hauled bacon. My go to hog gun for night shooting is my 30-06. I just hate shooting them in the chest because the 165 grain bullet just explodes them. As for a 225 grain bullet....jeez...loweez. They aint grizzley bears. Quartering away shots on hogs I will do with my bow if I HAVE to. I will let them walk if I have my rifle because I just hate cleaning a pig that has had his intestines blown to goo. I get to whack pigs all the time though so I can be selective. If it is the one hunt you get a year I guess take the shot that is offered. On another note the 22-250 is my buddys go to gun for just about everything on his farm. That little bullet hits them in the head and it feels like a bag of mashed potatoes and marbles. It just shatters their head and if you hit them in the chest it looks like a grenade went off in there. I think that little 55 grain bullet is WAY underated.
Show us some pics when you get back.
Remember to shoot them small.
