How many did your group shoot beyond 150 yards? In 10 years of hog and deer hunting 95% of the animals killed were well within 150 yards. The longest was just shy of 200 yards.
You can get up close to hogs here at night just stay down wind out average shots are well within 100 yards usually within 50 yards. If you want to shoot long distance you can most of the fields I hint are on average 1000x1000 yards with wind breaks inbetween, but I prefer to get close.
