Hey guys...just wanting some of your guys opinions on Grizzly Single Bevels. I've always shot Zwickey and Woodsmen 125gr. I like Zwickey a lot, but would like to try a Single Bevel in hopes of more penetration on bone. Also wondering if I could go any heavier than a 125gr from 50-55# bow? Any advise would be appreciated.
Thanks
AJ
Probably would be wise to go heavier than 125 grains if you still get good arrow flight. Zwickey and Woodsmens are good heads. Tough to beat. Not much to be gained, IMO.
I've shot and still hunt with some single bevels. Because the blade angle/bevel is more acute, it is possible to get them a little sharper than double bevels or 3-blade heads, but any will do the job if put in the right place, and even sometimes when they aren't. I think high weight forward and a skinny shaft on a well tuned arrow will do as much or more to increase penetration as a single bevel head.
But, if you have the itch, might as well scratch it and come to your own conclusions. Good luck.
You don't say what shaft material you are using, but with carbon shafts I am shooting 225 to 275 grains up front, depending on the bow. I use either a 50 or 100 grain brass adapter and a 175 grain broadhead.
On woodies, I've used the 160 grain Grizzly El Grande. They fly great, but I have not had an opportunity to test them on game yet. I like all the weight I can get on the front of the arrow for better penetration and arrow flight.
You can get the new grizzlies quite sharp and if you increase arrow spine accordingly you can certainly shoot the heavier heads. Also, not shooting into bone is a good idea even with heavy single bevels.
Excellent arrow flight and the easiest to sharpen broad head I have ever used.
grizzly vrs woodsmen vrs grizzly vrs woodsmen...
I make myself crazy trying to decide. or maybe magnus 4s....
I really don't believe it makes much difference weather it is single bevel or standard bevel. other than a marketing ploy. An sharp edge is a sharp edge. SHOT placement is what is important.
I realize shot placement is the key, however those shots aren't always perfect. I lost a nice buck last week due to a shoulder blade hit. I'd like to try and have a heavier arrow for instances like that. Not sure what grain my arrows are, wish I did. I just know they are your average cedars. 28 in long. 50-55 Spine
Thanks for the advice guys. Anymore would be greatly appreciated.
I have them mounted on wood arrows if you want to swing by and check them out.

Jeff, While I respect your right to your own opinion. Dr. Ashby has done far to much research proving the effects of a single bevel.There for I must respond to your off handed claims of a marketing ploy. Dr. Ashby has done all of this research at his own expense with ZERO compensation.His research is offered only to help those who are interested understand the effects of various broadhead and arrow designs on both hard and soft tissue. If you are interested in reading Dr. Ashby's research it is available here on Tradgang. If you choose not to accept his research than so be it but it most definitely is not a marketing ploy.
For what its worth we all agree that shot placement and a sharp broadhead are priority one when it comes to quick clean kills.
A.J. If you have any questions for me concerning Grizzly broadheads. I will be happy to answer them for you. I am going to be out of town for the next week but I will get back to you as soon as I return.
2014 is the 30th anniversary of Grizzly broadheads.

It is not off handed. It is from my personal experience in the field. True life real live animals. With grizzles, bear, Magnus, and various 3 blade all with 8.5-10 grains per pound. I believe HH claimed that 3 to 1 ratio in length to width works best. And that holds true for me.
Great BHs that easily get razor sharp and stay sharp. They fly great and are easy to set up. They are very tough and of the highest quality for a reasonable price. I use 200gr K for 60 to 75# set-ups along with some ZD4s sometimes. It's nice to break down the far side shoulder on a good q-away shot for added damage and I like 2 holes better than one if possible.
What's cool about the single bevels is the hole they make. It's a lot more than a regular 2 blade.
The new grizzlies are great heads. Very durable and very easy to get sharp. I've never gotten another head as sharp as I can get these. The "S" shaped hole is obvious as well.
My single bevel experience with the Grizzly heads has been nothing but fantastic!
I never could get a any other head I have used anywhere near as sharp as I can any of the three weights of these Grizzlies. I have taken 5 deer with them and one hog and the performance has been superb.
Also the Grizzly's have features packed into them that you will find in a head that cost twice as much.
My last two deer have been with single bevel and I'm certain I would also have killed them with the Woodsman that I had used earlier however I love sharpening and touching up the single bevel. Once the back side of the bevel is perfectly flat touching them up is a joy and gives me something to do when I get bored on a hunt. The rotation of the blade however is something to see when it works through more dense material. Lung material maybe not so much to observe the effect, but I had a doe wheel around on a shot behind the shoulder and the broadhead actually came out the front of the deer carving almost a perfectly round whole that led to super blood loss.The physics behind the wing design is pretty cool stuff as far as I'm concerned.
There is really no question that the Grizzly/Kodiak broadheads are effective killers so I'll address the question of head weight. The doe pictured below was taken with a Great Northern Critter Gitter drawing 50 lb at my 26" draw and shooting a 200 gr Kodiak mounted on the end of a fir arrow. Total arrow weight was about 580 gr. The shot was a little past quartering away, entering behind the last rib and getting liver and one lung before stopping in the far shoulder. She took it to the fletch and made it maybe 60 yards if that.
I shoot several different broadheads and have been very impressed with the performance of 200 grain heads and high FOC's. You will have to up your spine about 10 lbs and do some tuning, just like with any other setup. Try them and I believe you will like them.

Scientific experiments vs anecdotal one-offs. No matter how many blades and designs, I've never seen better results with any head than a griz. I've been confused following blood trails because there was simply too much blood, a sprinkler effect with them. I've shot a ton of deer and never seen such results with another head. 2, 3 or 4 blade.
I don't think you can beat the single bevel Grizzly. The design work very nice with both low and high poundage bows.
The performance of the Grizzlies blows away any other broadhead I've used, I've killed moose, black bears, a grizzly bear, and the other day, this Sitka blacktail. 16 yards, quartering to, slightly downhill, with a 45# bow. chopped through his shoulder blade, the bone spurs along the spine, cut 3 ribs, and got 16" initial penetration. they aren't huge deer by any means, but 16 inches...and through a lot of bone. he only made it 75 yards, and after breaking the arrow, the point was near his pelvis. hard to argue with that.

because someone is gonna ask..the bow in the background is my dad's, forgot it was hanging there! :)
I guess I'll give then another try. They come in right and left. Right bevel for right wing and left for left wing?
from my 53# Berry longbow I'm shooting no less than 160gr grizzly's, on a 45-50 surewood shaft that's bareshaft tuned for 28" BOP on a 27" draw, they fly perfect and are 640grains total.
the one thing I personally don't like is unless you file the back corners of the broadhead down they don't come out of my back quiver easy.. BUT with that being said I wouldn't change ask them to change the design I just use a file to round the corners a bit.
find sharpening them is easy if you don't rush, and they retain that sharp edge all season.
BearCrkBandit - I thought you were just two fisting it with your bows and using some type of double mouth release. Archery's version of a side by...
Joking aside, nice buck! Congratulations!
I look forward to going to the Kalamazoo show and talking to Bill (hoping he will be there) about Grizzlys and his new 3 blade. I am sharpening inept and do better sharpening 3 blade but I also like to hunt low poundage bows in the late season and know two blades are better for those set ups.
With woody weight add on to my 190 Grizzleys I have 260 upfront and they fly great!

Yes, that is correct. From my understanding, the single bevel spins the arrow as well as the fletching, so you want to make sure that they're both spinning the arrow in the same direction.
I know it has been on here several times, but care to share your Grizzly sharpening techniques. I've used sandpaper and also file to sharpen and kill 2 deer with Grizzlys. I know many of you have a perfected method that turns out a great edge.
The 160 Grizzlys have always worked for me. I guess I'll have to try some of the new ones.

I just got some this year,and bought a KME sharpener to sharpen them with. I used a coarse stone to get the bevel established and then went to a finer stone and then finally used a arkansas stone. Now that they are sharp I just touch them up every once in a while with the arkansas stone.
What Bill Dunn says.
The research doesn't lie.
Lots of guys using them and they all say they work great.
Mine are the 149s with 35 grn adapter.
Sharpening is as easy as using a file to raise a burr and a jewel stick to take the burr back off. A head can be shaving in under 10 minutes.
The single bevel heads is most defiantly NOT a marketing ploy! They aren't anything new either, native people have used single bevel points for thousands of years and for the same reason we use it now - it gets sharper.
I have taken deer with Woodsman, Zwikey, and Muzzy heads... They all work great when put where they need to be. Here is the test, pull all of those head out of the dirt after they have passed through the deer and try to shave hair, isn't going to happen. Now do the same test with a Grizzly or any of the other quality single bevel heads... they still shave hair with ease. Quality of steel has a lot to do with that, but 99% of the single bevel heads are made with top grade steel. Clearly I'm a believer in single bevels and the Grizzly's are at the right price for me. :thumbsup: that's my .02
I just got bought some of Bill's new 235gr Kodiaks. Really looking forward to these!
I have shot deer with grizzlys and zwickys. I think they are both great BHs. I stepped up my arrow weight to 630grains out of a 53lb bow. I shot a doe this year shot through both front shoulders with a zwicky. I like both BH.
My wife blew through both scapula and out on a year and a half buck this year with a Zwickey. It was towards the rear of the scapula, but what impressed me was that the arrow went straight through no deflecting. She has gotten unreal penetration with an original Grizzly as well. That arrow was very old and was a right winger on a left wing arrow. The entire arrow was in the deer and the head was lodged in the far opposite shoulder. What we have between Grizzlys and Zwickeys are two incredible products, that will work for anyone. I think that, for some, the Zwickey is easier to sharpen. The last deer my son shot with a Zwickey Delta, "It was just like the other one, an unreal amount of blood." These heads were all just file sharpened with just a bit of work with a diamond hone.
I have always been a "big" broadhead fan and would not even consider shooting a two blade broadhead under 1.5 wide. The smallest I hunted with then was a Zwickey delta and that was a small head for me. I now shoot lower poundage and really enjoy straight end bows so I`m no longer shooting bows that I feel good about getting an exit wound with the big heads.
I got some Grizzly heads in a horse trade and Fletcher sent me two of the wider ones as well. IM SOLD. I get pass throughs and out of 4 of my 5 deer killed with them this year I have yet to bend over to look for blood. I got side tracked on one but after getting straightened out the blood was profuse.. The "twist" does happen and leaves more that a slit. i killed a pig with one and the arrow went through the ribs and split the whole length of the leg bone.
to add to this a buddy of mine shot lengths of a 2x4 board with big double bevels and then with Grizzlys . On all shots that the heads hit across the wood grain the arrow just stuck in the pieces of wood. When the doubles hit with the grain they also stuck in the wood and never split it. when the singles hit with the grain the pieces of wood would split in two pieces.
I`ve killed a few deer and pigs and I tell you I have as much or more confidence in these heads as I have in any head I`ve ever shot.I`m going hunting this evening Lord Willing and I`ll have a quiver full of them.RC
RC, I agree totally. I shoot lower poundage (50lb) bows also and the wider heads simply have more friction and don't penetrate as well as a thinner head (tested on critters). All my blood trials have been like yours as well with my Grizzly's.
How do grizzly s Compare to Land sharks. Blood trails. And penetration.
For me nothing beats the blood trail of a big Simmons or a big Snuffer. BUT like myself if you shoot the lower poundage the Grizzly very much gets it done and penetration is the whole reason I tried them.RC
