I have several .30 cal ones and one of the Cold Steel big bore .52 cal ones. I sold it, but did have an attachment that used co2s and fired bolts! THAT was cool. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> I’ve read an easy way to make darts is to use bamboo skewers and cotton balls. You could also get some thin spring steel, and cut your own darts and sharpen them. When we were kids, my brother and I took some small dia PVC pipe cut to length, and used push-pull thumbtacks in them. It worked pretty well. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />

I’ve used slings before too. In fact, I’ve been thinking of making another one soon, and I was thinking about it again just today. My brother and I used to go to an overhanging bluff above a lake and throw rocks into the water. We could throw golf ball size or bigger rocks clear out of sight. We’d have to wait for the splash to see where it landed. We’d compete for range, etc. After a while though, your arm would be aching. It’s good exercise. I thought before if you used a ping-pong ball to make a plaster or whatever mold and then pored round lead balls that size, they’d due some SERIOUS damage. You could melt down old wheel weights or something for the lead. Website for ya: http://slinging.org/
