The load I used to use was 90gr Pyrodex RS and a 245 gr Powerbelt. I know the bullet I'm using now is much heavier but after so many disappiontments, even with well placed shots, I will not be going back.
As far as licensing for hog hunting in Texas, the Texas Parks and Wildlife rule book states that no licence is required. From page 53 TPW Outdoor Annual,"A hunting license is not required to hunt the following: Depredating feral hogs, if a landowner or landowner's agent or lessee is taking feral hogs causing depredation on the landowners property."
So since I lease the property and the hogs are causing damage to the pastures by rooting, my guests and I are not required to be licensed. I do have one because I hunt so much more than hogs.
