Open or silent

I know this to be fact. U can cut a rice field with a combine and tractors and grain carts running around at the same time shooting a hog here and there. Cross from one patty into the next and jump more hogs in that patty. I have jumped hogs in one patty shoot at them they cross into next uncut patty and just stop. They will also not run until the machine is right on top of them and breaking into open is their last option. Me and the guy and girl that helped with harvest last fall killed 45 pigs of all sizes in 16 days while cutting rice.
