Your absolutly right NYLES , I had given the shot angle alot of thought and figured that maybe I had hit the on side lung realy high and missed the off side on the exit making the blood have to exit the top of the lung and fill the chest cavity to exit out of the bottom exit hole. I was still realy dissapointed witht he sharpness of the blades and butt head I talked to about the problem.
I have tried the newer Grimm Reaper heads with good success and they shoot pretty good locked open as well.
I'm shooting a Bowtech VFT Samsom at 104lbs and my arrows are in the 530+gr range so I'm just over the IBO 5gr per lb of draw weight and its shooting around 310fps-ish, I have cranked the weight up to 113lbs with the bolts bottomed out and shooting a 500gr arrow got 342fps but it was LOUD !! I get great accuracy and its not to loud at this weight. he Rockets I shoot are the 3 blade Hammer head with a bigger "bone buster" tip replaced , it cuts a 2" hle thats simply awsome.
I have reciently stitched my fixed blade heads from the Magnus Snuffer to the newer Razor Caps , they fly realy well and offer alot of flexibility with weight adjustment from light to heavy , in the 150+gr range
