Or should I go the bow route?
I don't know anything about that rifle brand but a .30-30 is pretty potent round. The biggest drawback to the .30-30 vs. say the .30-06 comes when shooting from a distance. A .30-30 is going to drop a lot more than a .30-06. If you are close enough the .30-30 should have plenty of power to do the job against feral hogs or even black bears for that mater. Most deer hunters I knew growing up used .30-06 because of the extra range. That is when they weren't limited to slugs.
You need a good kill shot like heart, lung or head. Don't shoot it in the butt. Get some hollow point rounds that expand on impact. Ball ammo (or full metal jacket it's called) will likely go right through and the hog might eventually bleed out, but in the meantime it will be suffering and plenty mad. Get good ammo, learn where to shoot and drop him quick. Be safe!!!
I know I don't want to be too close to the hogs, I'd like to get them from my porch. I had found a great 30-06 and this confirmed it. I choose Savage because of it's popularity with hunters, and it's reasonable prices.
Gee, why not use a slingshot to give 'em a sporting chance? Just kidding; I know feral hogs are nasty and vicious. I have heard of people taking one out with a slingshot though.
Right, the vitals are in between the shoulders, not behind, and so the ideal spot is their neck area, i heard a butt-shot isn't a bad shot, but not the best either.
Even a small caliber like a 22 will drop one if the shot is placed right, but the 30 30 is much better.
