If you move the dogs away the pig will run. most pigs get bailed in very tight scrub, people wont shoot if they dont know where their dogs are and most guys wont let someone else shoot a pig bailed by their dogs, it takes a lot of time and money to get a dog going well.
Generally guys who run bailers use a rifle with a big slow bullet so it wont exit, the .357 and .44 mag are popular so is the .30-30.
A lot of guys including me run holders which hold the pigs ears or head until you tip it over and stick it, its good fun and way easyer than carrying a rifle around the place
