High Country Posted July 27, 2009 Report Share Posted July 27, 2009 Accidentally ran into a "study" of the penetration of different broadheads...the "study" was pretty well done, and the conclusions were also pretty good, without any perceived bias. http://images.google.com/imgres?imgurl=http://i175.photobucket.com/albums/w124/bow_project/BH%2520test/bear.jpg&imgrefurl=http://wibowhunters.proboards.com/index.cgi%3Fboard%3Dbroadheads%26action%3Dprint%26thread%3D588&usg=__AHvmWhqH-ZZn9hRUiBQU4tFVApc=&h=476&w=631&sz=46&hl=en&start=3&tbnid=Rfl0hYFse5TKhM:&tbnh=103&tbnw=137&prev=/images%3Fq%3DBear%2BSuper%2BRazorhead%26gbv%3D2%26hl%3Den Quote Link to comment Share on other sites More sharing options...
PotashRLS Posted July 27, 2009 Report Share Posted July 27, 2009 Pretty cool little study you guys did there. Kudos for all the effort it took to put that together. I found your results very interesting but not overly surprising. I think you did a pretty good job keeping as even a playing field as you could.

hunterwebb Posted July 27, 2009 Report Share Posted July 27, 2009 hi high country after your study are you still shooting muzzy Quote Link to comment Share on other sites More sharing options...
stcif Posted July 28, 2009 Report Share Posted July 28, 2009 Some of what I read seems to mirror what I have read from Dr. Ed Ashby. The best penetrating and effective broadhead design based on the Natal study was a head such as a Grizzly single blade with a tanto tip. That head design penetrates bone better than any other design. Keep in mind that arrow mass has more to do with penetration than KE or arrow speed. Interesting read. http://www.tradgang.com/ashby/ Quote Link to comment Share on other sites More sharing options...
HUNTINGMAN Posted July 28, 2009 Report Share Posted July 28, 2009 I am going right now to check the tips on my muzzy heads,I have had them for a couple of years so they may be ok.As many times as I have put them on and taken them off I would have noticed if they were that rough,I think I am ok.

Straight Shooter Posted July 28, 2009 Report Share Posted July 28, 2009 So, I lose 3.6 lbs. of energy when I hit an animal to get to the blades, that still leaves 64 lbs. of energy to push the blades through that animal. I've not had a prblem with pass throughs or bone breaking with my Muzzy's and don't plan on changing from them. Quote Link to comment Share on other sites More sharing options...
High Country Posted July 29, 2009 Author Report Share Posted July 29, 2009 I did not perform this study...just found it online... When I first started hunting, I began using Bear Super Razorhead cut on contact broadheads (125 and 145 grain)...killed a couple of deer with those, including my longest shot of about 35 yards. About 10 years ago, I had a Razorhead to fail (it folded up double...think a U shape) when it hit the ball of the shoulder on a doe about 20 yards out. It destroyed the shoulder (eventually killing the doe), but failed to penetrate into the chest cavity...I lost that deer. I then tried Kolpin's twisting broadheads...no longer manufactured...at least by Kolpin...I picked up three 6-packs for about $1.50 each on clearance sale...they were a chisel tip design with the blades set at an angle (not perpendicular to the center) to improve flight...and that it did...they shot better than field tips...I recovered every deer that I shot with them (most busted through bone and penetrated 4-8 inches into the ground on the offside). I ran short last year, so I did some research and based on their reputation went with 100 grain Muzzys (same weight as the Kolpin broadheads)...I do plan to sharpen the trocar tip though...

buckee Posted July 29, 2009 Report Share Posted July 29, 2009 That is quit the study you've done. I'm impressed. I'm still shooting the original Montec G5's, that you have to sharpen yourself. When they wear out I'll switch to the newer ones. I love my G5's Quote Link to comment Share on other sites More sharing options...

Interesting...I have a "Kolpin Twister" on an arrow shaft, under a fan and beard, that blew through a turkey like it was not there! I could'nt find anymore of them and now I shoot Muzzy 3-blades. LOL...thought it was funny when the person who did this study mentioned his 4 reasons for doing this study and thought that #4 was probably more true than any other: Quote I volunteered to do that comparison because: 1. my Son and I have a bit of a broadhead collection (about 300 heads) 2. I hunt with my own homemade broadheads so I can be impartial. 3. I'm into this sort of thing. 4. Everybody else had a life. Quote Link to comment Share on other sites More sharing options...
fly Posted July 29, 2009 Report Share Posted July 29, 2009 I've had several posts explaining my poor results with Muzzy. This gives a good enough explanation to me. Why did they stop sharpening the tips? I know several people that stopped using them because of poor penetration. Quote Link to comment Share on other sites More sharing options...
GWSmith Posted July 29, 2009 Report Share Posted July 29, 2009 To All of Those People Who Dont Want Their 100gr 3-Blade Muzzy's ;)SEND THEM TO ME....I'LL KILL DEER WITH THEM;) While you go out and pay what is it...something like $30+ for a 3 pack of the latest and hottest thing out there.
