grizzlies and Left wing fletchin

[String Cutter]

Was reading in the TBM some about single bevels... It got me to thinkin??? If you're shooting a left wing fletchin with a grizzly what affect will the arrow spining the wrong way  have on pentation?????? Is grizzly planning on changing over to a left bevel??? I find them hard to sharpen anyway with a file. ... The bevels on the wrong side for a right handed person....????

Someone will come on here and give you directions to which of Doc Ed Ashby's threads discussed at length bevel and penetration in flesh---or search his name for posts, but there will be a lot of good uns.

it is supposed to take alot of penetration away, more than if you just used a double bevel broadhead because not only do you waste energy stop rotating you have to rotate the other way.

i have shot them with left wing feathers and still had great penetration.

[String Cutter]

So for those of us that shot left wing??? We shouldn't even bother shootin grizzlies?? Or should find a left bevel BH???

Zwicky "No Mercy" heads are available single-bevel, left wing as are the new Eclipse single bevel.Specify when you order.
Dr. Ashby advised not to shoot grizzly's or any other right bevel head with left wing, it is highly counter productive and actually decreases penetration.

Ron Swartz, KME Sharpeners (Sponsor)has offered a line of broadheads he'll grind single bevel, either left or right, for a decent price.

It's a precision process, working from blanks. Not all heads will be offered left, but some. I spoke to him recently and he said STOS in varied weights and Tusker in varied weights. There was a thread on here where he listed them.

I'm not sure Griz was one he's doing left bevel.

But w/ Ron's service, other broadheads than those commercially available will now be available to us sharpening impaired folks.

If you are not hunting big boned African type animals I don't think it matters much.  I shot a whitetail doe a few years ago with left wing fletching and a Grizzly head and it zipped right through her.
 Trad archery is a relatively simple sport and I think lots of folks try to make it more difficult than it actually is. JMO  Pat

I've been shooting Grizzlies at whitetails for years without any problem. They will always be found in my quiver whenever I take to the woods no matter what wing my feathers are. I agree with Pat, some people just seem to be trying to complicate things. Keep it simple and keep those grizzlies sharp, that's all you really need.

Having followed Doc Ashby's research articles, I'd only wish to weigh in on clarifying one point, at least from my perspective.

He and I aren't "best buds" by any means---as many folks here are much closer, but I've come to admire his tireless efforts.

As I read him in his published articles and emails to me, I do NOT believe he's trying to sell or condem anyone for their choices--just trying to share interesting data.

My take on his input is he's providing more data than most of us get from our own hunting...and he uses some basic research principles in trying to limit some, and I mean "Some" of the variables in any shot/recovery.  After all, many of us at one time in our career, lost an animal! Can't hardly find out what went wrong when we've "lost" the critter, so some of us get nosey about what might have happened... Doc's work kinda gives some ideas on how things work when they "don't work" so good.

I've looked at the single bevel broadhead and matching feather orientation this way:

First, I went to carbon arrows for hunting to elminate as many variables outside of the chunk of variables I throw in the mix each shot I make... that is to say, I practice a lot but I make SURE my arrows are straight so I don't feel I have to get anal about checking them constantly.

Second, it sorta's like when I lived in MT...buds used to say, "If'n ya ain't never been throwed offa horse, ya just ain't rode much!"

Most of us have had "marginal" hits happen...many, many reasons---and lost a critter or two.  We read it here all the time!

I look at the bevel vs. feather thing this way.  

IF...and only IF... you think it's worth it, then this new "data" helps folks find ways to MAXIMIZE the things we CAN control to get the ultimate amount of penetration IN ALL CIRCUMSTANCES...by getting involved in some of the results Dr. Ashby has shared.

I will continue to tune arrows, shoot all my shafts w/ broadheads prior to hunting at varying ranges to ensure they fly well, shoot from tree stands this summer at varied distances and angles, etc.

I'll also stick with all my left wing feathers, but---but this year, just to help if I should happen to get a bad shot and hit shoulder or something, or the critter moves tween release and arrival... I'll now use what I've learned about feather orientation and single bevel broadheads by shooting left bevel broadheads to match the left wing feathers I shoot.

Am I saying it's "unethical" to not do so?

Heavens NO! I don't think Doc Ashby thought so either. None of us should judge another.  I take it he's just sharing interesting information about arrow flight, characteristics of broadhead strength and now, the effects of single bevel cutting edge on tissue and how feather orientation affects that...

So, nope...doesn't matter a whit if you do or don't! Just interesting information and for me, it's kinda like stickin my finger in a light socket...Once I learned that ain't a good thing, I don't do it.  

I like to "tinker" and I sure feel obligated to minimize my own screw ups, and I have a bunch...so I will opt to do anything I learn that increases my bow's efficiency, my arrows flight or how to improve penetration SHOULD something go wrong.  Meanwhile, I keep trying to learn how to shoot better and make better shot choices, too.

I'm not trying to fan flames. Just the opposite. Doc's not around to share his own feeling and it just seems that somehow his shared input has gotten ramped and possibly interpreted that he's on a campaign to change folks... and I just don't read that in his writings.

Just another viewpoint. Peace out...

I bought a right wing clamp for my Grizzlies, but I slapped one on a woodie last fall with left wing feathers and that slid through a doe so slick she honestly did not know she was hit.  She browsed down the hill until she keeled over.  Might make some difference, but might be minimal on smaller whitetails.

[Doc Nock]

I've put ole Mag II with 5.5" feathers through a doe some years back... caught everything perfect...never a problem.  Never shot anything with a single bevel... and did fine.

I'm just thinking that if there is some small way to hedge the bet IF...IF something would go wrong with a hit... I'll go with it.

Every deer I've killed with a stickbow went less than 100 yards... most keeled over in sight.

But I'll still try what I learn to be "better" if it might help ina  tight spot...

Doc Nock has it squared away near as I can tell.  Doc Ashby's research is for informational purposes only.  Use it dont use it.  Its probably the best research you can get on bowhunting.
