Thumbtacks on a board at 20 ft, someone mentioned shooting at the bit of an axe, but a wedge of steel stays in place better, if its mounted securly, and clay birds, balloons, or anything that will shatter, break, or explode placed on either side of the axe will draw a big crowd of spectators.
The only downside is that someone has to replace the "targets" after every shot.
I remember the old days when many rendezvous used to shoot two charcoal briquettes. The shooter had the option of shooting a third briquette or an egg. The egg was worth twenty points, vs ten for a charcoal...if it was hit. A miss deducted twenty points unles the shooter ate a raw egg kept in a cooler.
The threat of eating a raw egg was sufficient to force me to concentrate extra hard. Fortunately, I hit every egg I shot at. :shocked2:
Another option is to make three different sizes of otherwise identical metal gongs placed at the same distance but separated by several feet. The smaller gongs appear to be placed at longer ranges and are difficult to hit. Most folks shoot over them.
Suspend each gong from a slightly different height to complete the optical illusion.
