Single bevel broadheads

[Iron_llama]

Blood trails seem to be more a function of the exit hole location than the broadhead that left the exit hole. A single bevel will (theoretically) make it more likely that you'll pass through the exit you're aiming for. If you can shred the heart and lungs on your way to the armpit you should have pretty decent blood.

That said I have both Maasais and Grizzlies but haven't killed anything with either (yet).

Bishop Scientific Method pretty good if you don't mind selling the house

Not doubting anyone's experience but I have had as good or better blood with single bevels since switching. My distance from shot to recovery has dropped drastically though, with many reacting very little to the hit and dropping within sight.

I like the 200 grain Cutthroats and am trying the 200 grain SB Iron Wills with bleeders. This year I have killed with both when I needed the help of a plan B broadhead/arrow.

Single Bevel and Blood Trails

As many of you, i'm on the search for a new broadhead. I currently have bounced around from Rage, spitfire's, walmart and amazon specials, and G5 montec's..... Spitfire's have been the most productive for me when it comes to blood. (Some good shots and some not so much..) Single bevel seem...

The one I killed with the Iron Will I hit just back of the last rib quartering away and the broadhead exited under the opposite side front shoulder. It took a while for this one to die as I hit intestines, stomach and 1 lung. I kept finding shaved hair along the blood trail because the broadhead was cleanly cutting hair off the inside of the front leg. If you look at the front leg in the picture you will see where the broadhead was shaving the leg, that is out of the box sharp. I found the front half of the arrow after about 500 yds and the back half stayed inside the body cavity.

I used the same 620 gn total arrow weight for both.

I have no complaints about the Cutthroat you can get it shaving sharp even after shooting them into the dirt and they get great rotation. The Iron wills come shaving sharp, are harder and have bleeder blades, my only question on the Iron Will is how much SB rotation do you get with such a short cutting edge. Now that I am tagged out and have a IW broadhead that will need touching up I am going to shoot into a Rinehart target and see how the rotation compares to the Cutthroat.

IWSB 15deg at 10.5 inches
Cutthroat 45deg at 7.25 inches

That's through gel

That's interesting, on the video he did that was a review of the IWSB he got 40 deg. for both with and without bleeders

It will be interesting to see what I get this weekend.

Hmm, I see that. I'd follow up with him if I shot these. I think he's pretty responsive and on some forums. Looks like he used to have a mat in front of the gel maybe?

Let us know what you get.

Looking to purchase 200g single bevel. Leaning toward Grizzly Stiks.

What’s your expert with Grizzly? Any other broadheads to consider ?

I called up grizzly stik yesterday afternoon. They actually talked me into the Maasai. Thanks for all the suggestions!

The distance to recovery is the saving grace for me so far. I'm not giving up on SB's yet, just disappointed in MY bloodtrails (2). I may look into the Iron Will's with bleeders. I lost the biggest deer of my life on a 10 yard broadside shot that looked like a great hit to me using an expandable so I really don't want to go back down that road.

I’m shooting 200gr single bevel Cutthroats. I haven’t gotten to shoot any deer with them yet but I really like them. Super easy to sharpen.

I wasn't doubting your experience, but I am doubting the lack of blood trail was due to it being shot with a single bevel. I've had similar experiences to yours with a double bevel...perfect broadside hits with an exit and very little external blood. Sometimes they just don't bleed externally. I wouldn't attribute that to the bevel design.
One aspect that a single bevel would have in it's favor is the angle of the bevel (of a single) does produce a sharper edge when compared with the same smoothness/hone of a double bevel. When sharpened with the same technique, a single is sharper than a double. The finer the edge the less effect on the clotting cascade. Ashby explains the concept better than I just did.

I do not shoot single bevels ,but I do shoot coc broadheads and I sent a 100g annihilllator through the back portion of a does lungs ,complete pass-through. I watched her walk to fence line and got spooked by 2 playing yearlings jumped in ,really bad bloodtrail she ran probably 150yd through some rough stuff no blood for 30yd then blood for 10yd all till we recovered her ,same broadhead sprayed trees with a centered lung shot pass through last year

They stay pretty sharp after foam. For the most part the strop is your friend to get that final razor edge. Once you figure it out and get the feel for it, it's not hard. Takes a little time. But not super difficult. I took the one I shot my deer with this fall and ran the file over it a little, stropped it on a piece of cardboard I had in the truck and I had a pretty good edge on it. It was a back up if I needed it. Still sharper than anything I was using before. But when they are super sharp, you can just slice paper like butter.
The air goes out of the lungs fast. Bleeder valve

I’ve shot SB Grizzly heads since 1991. Blood trails are generally a direct result of how sharp they are. I’ve shot tons of deer with Trad and wheels and used heads of all sorts, but the Griz (or that genre) is always my mainstay. I sharpened with a file initially and they died quick but blood sucked. You have to make sure the angle is low enough on the bevel to get stupid sharp, I stone and strop, and make sure it pops hair so easy it’s scary. Then, I’ll tell ya, blood trailing will generally be a piece of cake. Typically they start leaking about the distance they actually tip over at, or from that point on. So you don’t get instant blood, but it will get to bleeding about 40 yds out and then just get consistent unless your shot was crap. If it’s right, you should get 2 holes, and never have to track crap. Both deer I killed died in sight this year. The one I shot with a crossbow and expandable got 2x farther than the griz SB kills…

I shot the 200 gn cutthroat and the 200 gn single bevel into a morrell dice target at 20 yds and they both repeatedly rotated 45 deg. +/- a couple degrees. I could not see a difference between the two heads over multiple times. This was not a true test as the Cutthroat had not been shot after sharpening and the IW was shot into a deer and recovered after about 500 yds. I was suspecting the longer Cutthroats to get more rotation.

I shoot Grizzly SB too. Should have mentioned that in the above post. I use mostly the 190 grainers on glue on inserts. My preferred method now is to use three files clamped down to the table to set the initial bevel precisely and then sand them progressively finer grit until I hit about 2000 and get a mirror finish. Then I do a final sharpen across the top of a car window and then strop. They are insanely sharp and will shave.

The sharpness has a lot to do with overall blood loss. There is a physiological mechanism called the clotting cascade. It is the body's defense against hemorrhage. A cut from a very smooth, fine, razor-sharp edge does the least to initiate this process, so this type of cut bleeds the longest.

trail worth a pic…that was a one hole blood trail

 

[overspined]

At the end of that blood trail…kind of a backwards photo scheme I shot him in the evening, couldn’t tell how the hit was. Went back like 3 AM, found him very quickly, took some pics, and had taken a blood trail pic as it was just insane. Had I seen that, I wouldn’t have waited to find him. Shot was 27 yds and he was out of sight immediately, and didn’t want to risk jumping him so sometimes it’s just a good bet to wait

What are the specs on that bow? Great buck by the way!

i started building bows after that, I don’t copy anyone but I always say if my bows look even close to his in finish work and detail i’m doing well LOL. I own a number of his bows. He’s been a wonderful resource to discuss building with. He’s been humble and knows I’ve killed a ton of deer with his bows. I am a fan
