All total, I have 10 shooting buddies, but it is very rare when we all get together for shooting. It's usually 3 or 4, sometimes 5 that show up.
We don't shoot at a formal gun range. Our shooting trips are combined with camping/hiking/exploring in several remote desert (Mojave) regions. Our trips are usually 3-day events, but a few of us have spent 5+ days out there. There's nothing better than camping, GREAT-tasting camp food, shooting in the fresh air and sitting around a camp fire at night!
Besides the "competitive" paper target comparisons, I "jury-rigged" a moving target that is a lot of fun and VERY competitive. If you're interested, please e-mail me for the info, for it's kind of difficult to explain in words. It's a pulley system which utilizes gravity for the moving target, and there are only a few parts to it....
probably less than $5 for everything, at your local hardware store.....and it only takes about 10 minutes to set up. Add to that, it's re-usable, except that the target board will need to be replaced every so often.
