Huh. I never realized the blood trails that I typically get using single bevel heads was that poor! Of course, if you are hitting animals in the guts and intestines you are not going to get a good blood trail regardless of what you are using.
John....here's my take on that....there is a thread on here started by Guru...'Do you shoot too far forward or too far back?....I want to think it was above 80% for too far back...what ever the %age was it was OVERWHELMING. Too far back is way more likely to be the 'worst case' scenario than too far forward.
Here is what I have found, from tracking not just my animals but my friends, Camp buddies on multiple leases, and dozen and dozens of 'group' hunts, most of which occurred right here on TG ....
I want to shoot the BEST broad head for the most occurring by far 'worst case scenario' as this has been my experiences .....
Gut shot....yes, you can argue all you want but a 4 blade or a Snuffer will leak more blood on a gut shot, and more than once I've seen multi blades pull out intestines that get caught on brush and leave a trail...and the end of the intestine trail the blood was better. The multi blades will cut more surface and just about every pass through I've seen, the broad the non-same entrance and exit wound shot blade rotation, I can't remember a time when it didn't show. Also, the multi blade will cut more surface through the guts and release more toxins putting the animal down faster cause it makes him sicker quicker....and no need to worry about bone on a accidental most frequent worst case scenario of shooting too far back. Putting them down with more toxins of an unfortunate gut shot again, not only happens much more frequent than too far forward, is best for both you AND the game as a most frequent worst case scenario is going to kill the animal. So, I want every advantage I can get, and the animal is going to go down and die anyway, so it better for the animal as well.
Now, that being said, I am NOT knocking 2 blades, they certainly have a place in some folks quiver, and I have had great blood trails the times I have used wide 2 blades....and one deer I killed with a narrow Badger head(story is a thread called 'from top to bottom' or 'the upside down shot...and that doe only made two hops and killed over.....I'm very proud of that shot I had to 'manufacture' and the results of such.
Again...I'm not busting anyone's chops....just relating some facts and experiences I've had in over 3 decades.
