just watched hog shooting viedo, ive shot a lot of hogs and coyotes from a chopper, while doing pasture managment& game surveys, most shots are from 10 to 20 yards its windy & bumpy an r-22 chopper has a really small cockpit, shooter and pilot are shoulder to shoulder,you are close to the ground usually 30-50 ft.going 30-35 mph, the m-4 & ar-15 would seam like the right choice of weapon, not so, hot brass flying around the inside of the cockpit hitting you in the face , hands, going down your neck , aint much fun, not to mention it gets all over the floor and can jam the foot controls, seen it happen ! heres a few suggestions if you decide to give chopper shooting a try.wear good wrap around glasses,double check your seat belt, dont eat a big greasy breakfast,take a 12. gage tactial with full choke 3" with heavy shot. it should shoot a pattern about the size of a volley ball at 15 yrds and basket ball sized at 20 yards.put a dove ammo bag full of ammo between your feet.the 12 ga. will knock the hell out of a pig at close range,gps your flight path, so you can go back on the ground and pick up the pigs, with a truck and trailer, if you you dont pick up the pigs you will draw every coyote and scavanger, in the country & and pigs stink real bad laying in the sun for a few days.who ever picks up pigs take a handgun,could come in handy,by the way 12 ga.shotgunshells are a lot easier to clean up than .223 brass and there wont be as many of them. p.s. watch for power and phone lines they can ruin your day
good luckgun)
