Used to do competitive target shooting for about 5 years or so, but that was just with a .22.
We went out into the country on a field trip once though, got to fire off all kinds of things (and pick up all kinds of shells afterwards).
Lessee...
A shotgun (shot sizes 12, 8 and OHGODMYSHOULDER-1), a .762 short MSSE, a .303 hunting rifle, a semi-auto .22 (much easier than the single-shot rifle, obviously) and a .44 magnum, which was awesome because I'm a longtime fan of Marathon.
Other than that, a flick-knife which I just liked to open and close; the occasional home-made weapon of varying (and occasionally dubious) quality i.e. a nunchuck, a blunt alluminium sword, a sai; a jo (Japanese short-staff) and a bokuto (a wooden training sword like in Ninja Gaiden only without the option to upgrade to the Unlaboured Cheese-fest).
That's about it, I think. Aside from the jo and the bokuto I haven't touched any weapon in years.
