I had plenty of free time today so I did a little field test of my own. The results kinda surprised me. I was under the impression that the heavier an arrow is then the more penetration you will get. Makes perfect sense to me. Anyway, I shot a Easton Axis N-fused that weighs in at 9 gpi then I shot a Carbon Express Teminator Lite Select that weighs in at 7 gpi. The Carbon Express got way more penetration and even held up longer. I shot the two arrows into a galvanized steel horse trough. The Easton went through the first side and didnt penetrate at all on the second side. The CE went through the first side and about 2 inches stuck out the back side. Probably would have got more penetration had the fletchings not got wedged in the entrance hole. Also the Easton broke on the first shot while the CE was shot into the trough 13 times before it cracked.
Next I thought about the Grim Reaper video and how they show it holding up so well. I wondered how many broadheads they shot until they got one that didnt break. After checking for myself I believe they used just one. I shot the GR through the same steel trough 3 times before it broke. I also shot a Magnus stinger 12 times through it before just a bleeder blade broke. Other than the bleeder blade it was still in "OK" condition. The tip of the Stinger was rolled over slightly but thats all. Either way both broadheads are good and Im glad I decided to put them in my arsenal.
Now I just have to rethink my choice in arrows because I switched from CE to Easton but after today I may be switching back the CE Terminators.
