It's always kind of funny to think back about those days.
When I was in college I had a couple buddies that I went shooting with. We kept our guns locked in boxes that were locked up in our wall lockers for our clothes. Drilled holes in the bottom of the wall locker, bolted the lock box to the bottom of the wall locker and figured between the lock on the door, the lock on the locker and the lock on the box our stuff was safe. Never had an issue. We cast bullets in the dorm rooms, we reloaded in the dorm rooms, we had a good time.
We'd go shooting at little spots off the side of the road where we could park the cars, walk a few feet away, set up our stuff and then walk farther to set up targets. Shot handguns (a lot) and rifles (not so much). Targets (mostly), old appliances, old cars people had towed away to get them out of their yards, dead limbs on trees, rocks hundreds of yards away on the ridge, and other stuff.
It was always neat to find a good load that made your handgun make you look good.
Still regularly talk and e-mail one of those guys (have not seen/talked to the other two or three in 36 or 37 years). We sometimes get to talking about the shooting and hunting we did during college. The funny things we did/got a laugh out of.
In those days we loaded our revolvers with 5 rounds. Not because of any misunderstood safety thing, but because we could get ten 5 shot groups from a 50 round box of ammo. Did the 1911's the same way (though I think I was the only guy with a 1911 in the college shooting group.)
You learn all kinds of things shooting all kinds of targets. What penetrates, what doesn't on different materials. Reality can be quite different from perception or the movies.
