a new target i have found is the mardigras coins they throw from the floats. also the large beads. i also stick a tooth pick thru an ear plug and stick them on branches and fence posts.
Anyone try the target from academy, shoot the 4 metal targets and they flip up, shoot the upper one and they reset? Bought a cheap one from airgundepot.com and it doesn't work at all but I like the idea. One at academy looks a little heavier.
I usually have a few cans of spray paint without nozzles, fun targets.
Clay pots. Once you put a few holes through them a crack will develop. After that you can shoot the crack then slowly break pieces off of it. Another favorite that works for competition with friends are sticky notes
Chalk, buy it cheap. Drill holes in a piece of 2x4 that fit the diameter to stand the chalk upright. Good for 22's at distance and handguns of any caliber closer.
