All of my arrows are fletched left wing. I am thinking about going with the 190 grain grizzlys which are right bevel. So my question is will this work ?
Thanks
Jeff
NO! At least not in a way that will give you any benefit to the single bevel. You can get left bevel broadheads you know. Get hold of Ron (Sharpster) at KME and he can get you fixed up with super sharp left bevel broadheads or you can go to several of the other sponsors here (like Tim Harms at Braveheart Archery) who can help you find what you need.

Amar is right on. dave
NO,,if you have left wing fletch you want left wing bevel.and vice versa..if the two are differrent they will counteract one another..
Why did Grizzlys work well for all those years? Guys were getting excellent penetration using griz broadheads and lw feathers. Bone busting penetration!! Now that the Dr. has published his studies it is and astounding NO, they don't work like that!! You MUST only use RW bevel with RW feathers and you won't get penetration any other way. I've read Dr Ashby's reports and understand the theory but why did it work in the field before his research? dino

If im not mistaken the Dr never said the old stuff would not work. He has just given us the tools and info to get the most out of what we shoot.
What Ed said, in a close paraphrase, as I recall, is that mixing feather and broadhead torque "could lead to decreased penetration." I suspect Grizzlies work even with "wrong" twist feathers because they have high ME (long narrow profile, smooth ferrule, etc.), are real hard steel and the El Grandes were until recently among the heaviest glue-on heads you could buy. The goal is to have the head twist as much as possible as it passes through an animal. This splits bone, creates an effectively longer cut channel, does a lot more damage in soft tissues than a straight punch-through, and "twists and slashes" hide on the way out for a larger exit wound. A good single bevel will overcome the opposite twist of fletchings, which is much slower. But why make it stop and reverse direction when you can give it a headstart with matching feathers? Soon enough many broadhead makers including Grizzly will be offering both L and R single bevels, so unless you need broadheads immediately, now is a good time to wait for the new offerings. That's what I'm doing. Dave
