there were two men doing the machinegun thing with a significant difference
one had his license to own the things and had a .22 full auto he was shooting in very short bursts (2,3 and 4 round). He was at the next bench and I laughed at him suggesting that it might be a bit hard to keep his groups very small. He agreed with a smile. He was a nice, older fellow.
The other guy was nice too (cop) but young. he didn't have a full auto but was doing what he called 'bump firing' by allowing his finger/hand to remain sort of stationary while holding a heavy semi auto with his left hand and getting the thing to jumping in a spastic way and setting off strings of non-aimed fire... all over the hillside.
one guy was trying to keep his .22 in a small area of the target
the other guy (the cop) was spraying his .308 rounds all over in a random way
guess who I kept an eye on?
