HPBT or SP for Wild Bore?

I want to know what will have the best stopping power for pigs. I have a 308 and load 180gr for pigs. I have the choice of either a HPBT(Hollow point boat tail) or SP (Soft point) Most of the shots will be at running pigs as it is a pump action so I need a projectile that will stop a pig in its tracks even if it is shot it the gut.
