NOT Swackers! Was sold some by Crossbow dealer. Practice head shot over target (was touted to shoot just like a field point)-never found it. (-$30). First shot a nice doe +/- 30 yds the bolt curved right past the deer missing it by 6-10 feet! I think the a blade deployed early and made it fly to the right. Went back to dealer-of course the practice head was dead on at 40 yds right next to the field point. He gave me 2 used Spitfires to try. Took a nice deer with each, that is what HE uses.
