While any of those calibers will do the job, shot placement and type of bullet construction that's heavy for caliber should come first.

I use a Ruger .44 mag carbine with 240 grain lead tipped copper jacketed shells. It's brushy where I hunt and it has plenty of knock down.

Moosehuntinkid -- my favorite hog rifle is an old Ruger M77 in .338 win mag. My favorite load slings a 250 grain Partition Gold at 2,750 fps. Some say it's overkill, but it shoots flat and it drops hogs on the spot as long as I am doing my job. You can take them with a .22-250 behind the ear, but that shot doesn't always present itself. So, I prefer heavier artillery.

338 aint much gun there WW

Need at least a 45 ...

Lott or Ackley , yur pick

Hello Jack. You would be amazed at how many people freak out when they hear that I use a "big ole" .338 on hogs. The rifle has a scope so it's better than my thumpers in low-light situations -- which is the reality more often that not where I hunt piggies........

Wow! You guys shoot some hefty calibers. On the other hand, maybe the hogs that I hunt are just smaller. In the area that I hunt, you rarely get one over 200 lbs. I personally like my 7mm-08. My hunting area is hilly and high - about 6500 feet so I like the lighter weight of the rifle. So far I have not had to use more than one round on any of the goats or pigs I have hit with it.

Well I have a 458 Lott and WhitWorth is having a 450 Ackley built as we speak .. We never feel undergunned in the states .. But the neat thing is you can load from a 45/70 level to full throttle .. Most people dont think about that , they just say " oh you have a _________ " ..

My 458 is used for everything from whitetail on up ..

Whitworth does the same ..

I know what most people think -- you don't need that much gun for hogs, but need has nothing to do with it at all. It's just more fun, and if I have a good time doing it, that's good enough for me! I shot a button buck this last season with my .338, and no I didn't need that much gun either, but it kills so well that I use it for nearly everything!

I apologize if my comments came across as critical. I guess I am just jealous. I wish I could shoot a bore well. I can be recoil shy and when I first started hunting, it took a lot of work to correct my flinching.

Rodney -- no need to apologize! I didn't read your reply as being critical! It is difficult getting used to shooting big-bores well -- it takes loads of practice (expensive practice!). I do a lot of handgun hunting and like with the big-bore iron sighted rifles, you need to stalk up as close as possible -- it's about as much fun as a person can have with their clothes on! It's not difficult to develop a flinch, but it can take a long time to correct.
