Low poundage bow with single bevel?

[WVltd90]

Does anyone have any experience with a recurve in the 40-45lb range shooting a single bevel? If so, on what kind of game?

I am worried with a lower poundage setup that the spiraling wound channel effect will cut down on penetration, but figure someone else has actually had first hand experience and can give me a little insight.

Thanks in advance to anyone who has any info.

Check out the Ashby Foundation website. They have tested a lot with single bevels and 40 lb traditional bows for penetration. Wealth of information.

It will make little difference, but a single bevel does rob some of the momentum to rotate the cut. I'd just go double bevel. Straight line is perfect. But it not like single bevels spin thru like a dang drill bit, its just a partial rotation. Often the tips are not as sharp on SB, I think that makes a bigger difference.

Beendare should be along soon thumping his two-blade bible and I agree with him 100%.

With a 45# recurve a sharp two-blade double bevel Ace will kill anything. Get close and stay away from the scapula.

I'm going to guess that a single bevel makes a noticeable difference in outcome with a traditional bow about 1 out of 100 shots and that 1 is not 40-45lbs.

What broadhead are you talking about?

I've done it on a handful of feral goats and pigs - no really big ones though. Bows between 42-45# at my draw length and arrows between 450-500gn. Broadheads have been Outback Supreme 200gn and Crafted Archery Covert 200gn. The Crafted is a super wide head.

No issues at all with penetration but again, the animals were smallish, arrows were well tuned, broadheads razor sharp, very close range, etc. Pass throughs are normal unless I'm hitting off-side shoulder.

No reason it wouldn't work on a whitetail at all but I don't know whether it's necessary to choose a single bevel specifically for the rotational cut. I've killed plenty of stuff with double bevel and they work super well.

Most the time under my 50lb set ups it’s a vpa 250 grain 3 blade or 2 blade double bevel. I have a pile of their single bevels when I was testing them for them, I like the edge retention better on the doubles, and the blade angle is better imo, closer to the 3-1 ratio.

I'm sure I'll receive some differences of opinion, but as an engineer, and as a trad hunter, I cant think you'd ever find a measurable difference in hunting situations. Pick single or double bevel, whichever you are most confident with. A accurate shot and a sharp broadhead are what matters. Good luck!

I would agree....no magic powers to a single bevel and zero advantage, only disadvantages.

In fact, it's a less supported edge that will roll/dull easier. Look no further than the evolution of knives. Sure there are specialized single bevel Japanese slicers...but those are made with super steel to make up for the less supported fragile bevel. Not what you want on a BH- fragile. . Plus they are a little harder to sharpen.

The guy that started this whole SB hogwash used to sell those heads with his name on them....and with the high temper they had to use to hold their edge a bunch of the heads were brittle and breaking. Guys were losing buffalo on those expensive hunts because their $40 a piece SB BH's were failing. Not good.

A 2 blade is the penetration champ on any arrow. The double bevel makes it easy care.

Single bevel grizzly broadhead. Bounced off the barrel after zipping through this guy. Not sure of total arrow weight but they fly pretty good out of my 50# bear. I am a single bevel believer, used them for a long time now. No clue if they are actually better than double bevel, all I know is they work. Seems like the guy who did the big study on broadheads felt the spiraling action was beneficial.
