i use them for semi wild chickens and rails.. very effective darts but damn difficult to make. if accidentally the blades are not aligned properly the darts tend to veer off course. my darts and blowgun are all home made. will post my gear soon. waiting for a new cam and a card reader. thanx guys.
well, duct tape comes in many brands. there is some exellent stuff on the grey roll in the hardware store. the colored stuff that is more for artwork is alot less useful, the cones can collapse and warp easily.
For long range shooting 75-100 feet. Balance at about 1/3 rd darts can be used like throwing darts. Very accurate and powerful going right through 3/8 " plywood at 30 feet the cone and all. Head size make way for the cone to collapse and pass through without any damage.
