Rick,I see you consider yourself in the minority when it comes to exit wounds.Come to New Zealand and you will find yourself in the majority.
Most folks here prefer the projectile to expend its enegy inside the animal
and not exit.In NZ the 30-30 is the #1 pig gun because with the right bullet
you don,t endanger your dog on the off side.I don,t hunt pigs with dogs myself,But pig hunting with dogs and a knife or a 30-30,357,or 44mag is big with the young guys.Anyway this is just me having a yarn again.
Catch ya later,,,JACK.
