Im heading to south texas this coming up weekend for a turkey hunt. Assuming i get one on the ground with a snuffer, i intend to try to lop a head off. I wasnt willing to pony up the 45 bucks for a pack so i built some of my own. The straws are a very critical component for good flight. My first test shot was at a 3 inch thick piece of foam like they use for target faces at archery shops. At 20 yards i passed clean through and landed 5 yards behind it shooting a 58# bob lee recurve with 450 grain total arrow weight. I made mine a 3 inch cut. I was very impressed to say the least. It left the straws on the front side of the target, just like it was supposed to. We will be rolling film on our hunt. If all goes well with the field testing, perhaps i will do a build along when we get back.
