I've been on a 100 acre place that was high fenced and kept pigs in. We stalked pigs with bows on the place. The owner had a hot wire down low on the fence to keep the pigs off it. But every night you'd hear at least one pig squeal that hit that wire. He said the boars would also try to fight other boars through the fence. He had to repair the hot wire often.
We use a heavy gauge net wire on one of our big hog traps. You should see how bent up it is where pigs run straight at it trying to get out. They can mess up a regular net wire in a hurry if they wanted to.
It is far more important to be able to hit the target than it is to haggle over who makes a weapon or who pulls a trigger.
