Well a park ranger down in LaGrange told us we couldn't shoot a pumpkin with a buddy of mine's new FAL because it would cause ricochets. Don't think they allow steel targets down there anyway, though with the general IQ of the majority of shooters down there I feel it isn't a huge loss, the guy setting up the .22 spinner target at 10 feet was a clue that there might be wisdom in disallowing steel targets.
Ammo bouncing off a pumpkin? Thats odd....
