I started a club a couple of years ago, affilaited with a local R & G club. The first year, they left their 3D targets out all summer. This past summer, they did not. So, we found some foam sheets, 4" thick, about 4x8'. We cut those in half and made some bases out of old 2x6's. All members then chipped in 20 bucks (we only have about 8 guys) and we bought some ethofoam animal targets. Screwed those in and we were off with 20 targets. The club bought the foam for us ($200) and the members spent $200 on the ethofoam targets. Even if we had to buy the foam ourselves, there would have been about a $50 investment. Over the winter, we shoot at our local Gander Mountain.
