i like the 30-06 myself

dont they stab those things with knives? lol seriously though i like the knock down power of my 870 express with red dot scope sighted in for 100 yrds

I have killed literally tons of them with my favorite old 30/06 and a 165 grain Remington Corelokt. Any cartridge in the 30/06, .308, .270, .280, 7mm-08 range will work fine. The 45/70 is also a mighty fine hog round.

In my neck of the woods the crop destroying b@$+@&ds get big. I've killed several over 500 pounds and many in the 200-300 pound class. They are typically covered with mud and on boars the shoulder shields (gristle, scar tissue and callous under the hide) can be quite thick thus sturdy bullet construction is a must. Light for caliber and lightly constructed bullets will open up too fast even on the average porker. Over the years I've used the 165 grain Remington Corelokt in 30/06 hand loads to kill many many hogs. I've found this old bullet to hold together well for initial penetration having enough left to drive deep, destroy tissue and dump energy. They were and still are inexpensive and they work. I've also used the various incarnations of the Barnes X with great success in the '06, .308 and even the 25/06. I once ran across a big old boar courting a hot sow and he was quite possessive. Five well placed Barnes X's in a sudden and intense firefight finally convinced him he didn't want any more and neither did I... When they get liquored up it is amazing how much damage they can take before taking that long dirt nap!

Stay away from small bores like the .243. Choose a heavily constructed bullet from the current crop of bonded core offerings or X's and slay the vermin. The only good wild hog is a dead one!

30-06 does the trick

I like using something with big stopping power too. You have to treat them like a very dangerous animal and you have to be able to plant those big tuskers on the spot. If you have ever been charged by one, you will appreciate big heavy rifle bullets or a 12 gauge slug. You are interested in stopping a charge from a 300-500 lb beast, just like with a charging lion. As Beekeeper said, angry big boars can take an unbelievable amount of lead. I have personnaly seen a 325 pound boar's shield stop a good .357 mag bullet with a quarter inch of penetration from 20 feet away. Although this is hearsay, a hog hunting guide said that he has witnessed the same with a .270 130g bullet and I believe him. I have been charged by two boars over 300 lbs and will never use a .44 Mag as my primary weapon again unless I am in a tree. A 12 gauge slug does the trick as does any good sized .30 caliber on up. I will actually be using a 25-06 with 117g bullets on Monday just because I will be walking a lot and that rifle is very light. I hope it is enough... a little 45-70 lever action would be ideal.

Double lung a hog with anything 243 and above will put em down. A 30-30 would be good for a brush gun, I use both 270 and 30-30 for hogs.
