Not so many predators over here but I run almost all bolt guns and shotguns even though I have permitted semi autos.
Foxes its a Mod 70 .222, Rem 700 .22-250 or T3 25-06 we dont keep skins
For Wild dogs on the rare occasion I get to hunt them its the 25-06 or CMC .300win mag.
And Feral Pigs a major predator here its any thing from the 22-250 to the 450 rigby and the pump shotguns.
I also shoot a lot of feral cats but for those I prefer a .22 cal 40gn travelling at better than 4000fps like the 22-250 or a 220swift.
