Ive been slinging for probably 2 years now and really enjoy it. Like Dan, my accuracy is nowhere near bow level, but I can nail a 4x4 target at 15 yards every time. Best shot ever was on a 1 foot wide by 3 foot tall buoy about 150 yards away. Nailed it smack in the middle right where I was aiming.
Here are are few slings that I've made.
