Looking to make the switch to shooting single bevel broadheads. Also, going to building my own arrows to shoot with the broadhead. Best head out there? I am a right handed shooter. Looking for opinions on direction of bevel and fletching? Offset/helical/right/left all the things. Thanks in advance.
Bevel needs to match fletching. Right Bevel and right spin tightens screw in points on impact - that's enough reason for me to stick with "RH".
I'm not a fan of short, stubby, thin "modern caricatures" of "single bevel' broad heads. IMO, they do not meet the design objectives that Ashby settled on. If it were me, if I'm going to do a short stubby BH, like the Iron Will, I'm going double bevel. I have experience with the Abowyer Brown Bear Single bevel, which is very close to the Ashby supported design. I have experience with the 2 blade Magnus Stinger (double bevel all the way, none of that buzz cut stuff), and over the prior 30 years I've had unfortunate experiences with many other broad heads including Muzzy's which are apparently "bad with the bone", and I say that with experience.
I'm buying a new bow this year and I will probably try the Iron Will 125 gr two blade, double bevel for Rocky Mountain elk. I'm getting older and weaker and so my draw weight is dropping, arrow speed are falling and trajectory is becoming more of an issue. Thus I may drift away from 625 grain arrows with my 210 grain Abowyer Brown Bear single bevels, in favor of a little better trajectory with a slightly lighter set up but still excellent (double bevel) broad heads.
I think the double bevels are probably a better choice than the single bevel in the form factor you are considering (light, stubby and relatively thin blade thickness), but truth is it probably doesn't make much difference one way or another if using that particular design on an animal as small as an elk (point being, Ashby's focus was breaching heavy bone, and heavy bone was defined as a Water Buffalo Shoulder bone). On an elk, your ability to get a pass through or adequately penetrate a scapula probably is not going to change a whole lot if you choose an IW or Magnus single bevel over their similar double bevel designs. But in those short, stubby, thin packages I'd personally tend to lean double bevel. Because I don't think you get the "magic" of single bevel without the design parameters and weight...
