East Texas Hogs...
They are easy to kill, calibers that I know have put them down by folks I hunt with are .243, 6.5 Swede, .270 Win., 7x 57, .30-06 and a 45-70.
Oh, and 00 Buck.
Local farmers love to let us come hunt the marshes and creeks around their property.
Several guys in town trap them, feed them for a couple of weeks and then sell them for the meat.
I have only had to shoot one the second time, he was running and I missed the heart...hit too far back...what a mess. I trailed him, 200 lb boar, to an small island and he got up and charged me. Mr. Smith and Wesson put him down.
