Range report

Dang I need to take some pictures.

in an hour we burned through
75 12Ga
200 45ACP
~300 22lr.

Conclusions reached:

Road flares do not ignite when shot.
45 ACP will not penetrate 1/4" mild steel (but will dent it and make a satisfying clang)
Shooting aerosol cans is uneventful
Shooting stuff is fun
