This isn't really a detailed review but a report of my experience so far. I bought one package of 100 gr Stingers and one package of 100gr Stinger Buzzcuts. I believe in not using target broadheads for hunting, but I wanted to see both types. I figured to use one set for target, then swap in the others for hunting. I used the buzzcuts for target, and they grouped really well. I won't say they are the same as the advertised field point accuracy, but they are still deadly accurate. In any case, I was happy with that so installed the standard Stingers on my arrows, and set up in my stand. Late evening, a big doe came in to 25 yards and set up broadside facing right. I held directly behind the shoulder, squeezed off, and thought I got a great hit by the way she moved. I couldn't see the arrow go, which means lumenoks are in my future. Anyway, I thought I heard her cough and crash about 40 yards up the hill. So, I gave it a bit, went to the spot (it's dark now) and found a couple spots of blood. On up the hill, a few more spots. Dad and I tracked a spot or two, almost 100 yards back into the woods, then nothing. The next day, in the light, we found nothing but white hair where the shot took place, meaning either belly or brisket. We covered the whole hill with my two brothers, and found nothing. Well, in order to further diagnose, I took my target up and recreated the shot. The buzzcut arrows were dead on. Two of the other Stingers, also within tolerance. The one from the night before, well, it was 10 inches right. I reshot it 3 times, and it was going heavy right every time. Close inspection shows one of the main blades has a helical twist to it. I fully believe that it ended up in causing a cut across the brisket and that's it. Right now I'm retiring the Stingers, and may spend some more time with the buzzcuts, as the serrations should stiffen the blades. In any case, anyone using these needs to look hard at them, and I'd recommend shooting the actual broadheads you're going to hunt with and then sharpen afterwards, as this cost me venison. On another note, we're 90% sure it was a superficial wound and the doe probably would have survived, had muzzleloader season not come in and our property getting stomped flat by the neighbor while we were hunting on our other property.
