I got 9 or 10 Prototypes at the PBS banquet in Cincinnati, they flew good, and I had good luck hunting with them. The weights varied a little but they were still developing the manufacturing process on the ones I had. I Shot three whitetail does with 190 grain heads out of my 58# selfbow Pigger. Got a complete pass thru on all three deer with good, short blood trails. I wouldn’t hesitate using them on any of the critters I hunt, including moose.
Like Blake, I had trouble locating them but haven’t looked for them in several years. Hunter liked them , I believe he is still hunts with them.
