Of course, most shot 223 - ARs, a Tavor, SCAR. One AR pattern 9mm with Glock mags.
However, there were two old Garands and an Spring M1A. I was impressed by:
1. They are noisy!
2. When the rounds hit the dirt berm, they blew up big old clods all over, got showered with little rocks for the closer targets.
3. They certainly pushed back the shooters for slower firing rates as compared to the tick, tick of the 223s.
Amazing how folks carried those big old things in jungles, the cold of Europe, Korea, etc.
Maybe I''ll shoot my 10/22 in the 22 division. I put a dot on it and a sling. Ping, Ping!
Just an observation as I tune out and head home.
