I use a 30-06 or a 9,3x62 or my rem 870 loaded with slugs. The bigger the better...

I perfer to use a .308 with a good 150 gr bullet. I would not recommend anything lighter than a .243. I had a hog run off last weekend that I shot in the neck with a .204, he ran off like it didn't even phase him.

although I generally use a bow, I have used my trusty 45 Long Colt rifle! Great brush gun, and plenty big caliber. As stated before....placement is the key!

To be safe, I would go witha .460 Weatherby Magnum in case you run into the next Hogzilla and he is twice as big as the latest one.

Caldoc

.308 Win.

Winchester Super X, 180-grain, ballistic Silvertip.

ok i have a 7mm 7x57 mauser would that work?

You bet it's enough, it's a great cartridge for that.

A Savage ML10-II muzzleloader is hard to beat. Makes you not waste that first bullet with the idea that you have a bunch more in the mag.

There are a ton of good choices.That 7mm 7x57 mauser will do it.Anything that will kill a deer will kill a hog.

I have a Marlin .444, with a standard model 336 type walnut stock and 22" barrel. I have used this rifle for deer hunting here in the midwest the last five years. Along with a 3x9x40 VX-2 Leopold.
This same rifle/scope I have used for wild bore hunting three times, and it does a great job also.
As far as the Marlin .444 caliber, I use Remington and Hornady factory ammo, as well my reloads too.
I had a Limbsaver recoil pad installed,thatis a great help with handling recoil for any quick follow up shots with the .444.
Last year I used this same rifle and scope hunting mule deer in some wooded hill country in Colorado, on a friends ranch property. It performed quite well taking a mule deer at a measured 140 yards, one shot kill from a sitting position.
I have a friend who bought a new Marlin in their .450 caliber. He uses it on white tail deer as well as wild bore hunting with a 2x7 variable scope.
