Art the feral cattle are not just in the canebrakes anymore. Place we hunt put 100head of cows and a couple bulls onto 2,000acres. That was 30yrs ago, they worked em for the first time a couple years ago, trying to get them all out. They got the ones stupid enough to go into a huge trap they built, then pushed em into pens on bulldozers and tractors with blades. Those that didn't get trapped or jumped the 7' fence to escape are not the nicest critters in the world. We went to work some young pups one day and bayed one of those beasts, it was not pretty.
I set a new record in the mile run another day when a cripple decided to hunt me and I didn't want to have to shoot it. You know a 12 gauge with slugs looks about like a .22 when 1500lbs of pissed off rogue bull is coming at you from across a cactus patch.
The guy I work with put 3rds of 20gauge #3 buck into ones head from 15yds away and the sucker never flinched, the tranquilizer they had hit him with finally took effect shortly after and they got him tied and loaded. Sold him 3 days later, no ill effects from that buckshot.
We've had some other less fun events with those rogues over the years, but the nice thing is most of the time they are spookier than deer and run like crazy at the sight, scent, or sound of a person. You'd be more likely to shoot a 10pt buck in that pasture than get within range of one of those rogues.
