The way to control big pig numbers is with lots of shooters doing a drive. Walkers and blockers. And disciplined shooters shooting safely. A Hunt Master knowing how to organise a drive. Easy with shotguns. Harder with rifles.

I would not be comfortable with trigger happy gung-ho sorts.

Night shooting with image instensivusing optics seems the most effective method in controlling stage populations of Feras in the last few years.
