You know it's going to be a good day at the range when preparations involve checking the tire pressures on the stuff you're bringing.
The cannon, listed for sale here earlier, at 22 degrees elevation, with 400 gr of ffg under 2 lb of concrete in a 303 can delivers about 600 yards range. Asking price will be $1500.
Muzzle velocity can be calculated, the proof is left as an exercise for the students. Ballistic coefficient for a 303 can? It can't be good.
I brought along the pedal air gun which when I arrived, drew comparisons to some of the improvised anti-aircraft systems recently seen in Libya.
One of the kids fired one of the 12-ga darts from it at a steep angle instead of toward the backstop. I found it embedded in the ground some 175 yards downrange. Great fun, every kid should have one of these.
NASA is the National Association of Squash Artillery. We may soon expand that to the National Association of Squirrel Artillery. Film at 11, as they used to say.
Walking up and down the line I saw a 2-bore rifle, an 8-gauge rifle, a .50, a suppressed Ingram .45, and enough more conventional stuff to keep someone drooling all day long.
The food was good too. Imagine a large Styrofoam cup. Now layer it with 1) mashed potatoes, 2) BBQ beef / chicken, 3) BBQ beans and top it with 4) Cole Slaw. Serve with a fork and a lemonade. Compliments to Juan, the chef.
