The importance of arrow speed is greatly exaggerated for hunting. The fastest bow is not near as fast as the slowest Whitetail Deer. Wrong! .... a bow shooting 260fps can nail a deer at 15 yards regardless of what that deer does in terms of ducking the string. At 320fps that distance goes out to 18 yards. Accuracy is the most important aspect because the deer does not care how fast the arrow goes by it. Speed comes at a price. Fast bows have features, like a low brace height, that makes them more difficult to shoot. WRONG! YEARS BACK THIS WAS A TRUE STATEMENT BUT TODAY...IN THE PRESENT...WE HAVE MANY SPEED BOWS WITH 7" BRACE AND MORE There is a lot of difference between shooting with both feet placed perfect on level ground at a foam target and twisting around in a treestand trying to shoot over a limb at a live deer. Speed also means noise. A bow that shoots an arrow at 300 f.p.s. has to have a string that is also moving at least 300 f.p.s. That string as well as the cables, limbs, and cams moving at high speed have to stop. That energy is absorbed by the bow and accessories and converted to vibration, which is sound. A bow string moving at 240 f.p.s. has less energy and of course less noise transferred to the bow. The arrow is also a source of sound that most people don’t think about. You have probably noticed the difference in sound made by cars driving down a highway. The cars that are speeding make more noise because they are moving through the air faster. The air pressure and displacing the air makes noise. The same is true of your arrows. The vanes and broadhead displace air. The air pressure against the veins control the arrow but also make noise. The faster the arrow, the more noise. Get behind something near the target and listen to different speed arrows. You will notice a difference in noise, just like the speeding car. A Whitetail will hear that noise long before the arrow gets there unless you are shooting at the speed of sound, which is about 1000 f.p.s. I THINK I AM GONNA PUKE ;D
This is more hype to try and give validity to a point Funny that until a few years ago , arrow flight was a non-issue.....it was never spoken of or considered an issue. Then a guy who was trying to find a niche for his product set up a camera and a mic and recorded an arrow in flight. Suddenly it's this big to do ;DMost people will agree that a traditional broadhead won’t group well at speeds over 280 f.p.s. That forces you to use expandable broadheads, which have a number of disadvantages over fixed heads. ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D WHAT AN IDIOTIC STATEMENT
HOW MUCH YOU GAIN WITH ARROW SPEED. There have been a number of studies on arrow trajectory at different speeds. Easton did an interesting one where they compared arrows of different speeds and weights. They compared arrow impact 5 yards before and after the target. In other words, if you shot at a deer that you think was 40 yards away and it was only 35 or was 45 yards, how far would you hit from where you held your sight pin. Here is a comparison with a 220, 240, and 280 f.p.s. bows. These would pretty much represent the range of bows for most hunters and you can make the same comparison between bows at different speeds. The numbers under each yardage show how much you will be high 5 yards before and low 5 yards after that yardage. SPEED 20 YD 30 YD 40 YD 50 YD 60 YD 220 f.p.s. +2 - 4 +4 -5 +5 -7 +7 -9 +9 -11 240 f.p.s. +2 -3 +3 -4 +5 -6 +6 -8 +8 -9 280 f.p.s. +1 -2 +2 -3 +3 -5 +4 -6 +5 -6 AT 40 YARDS WE ARE SEEING SOME SERIOUS CHANGES FROM 240 AND 280 BUT NOT AT 20 - 30
ALSO...@ 40 YARDS WE CAN MISS JUDGE DISTANCE BY 10 YARDS AND STILL HIT VITALS ON AN AVERAGE SIZED WHITE TAIL (WHEN HOLDING CENTER MASS) BUT NOT AT DISTANCES BEFORE AND AFTER
USING THIS CHART WE CAN SEE THAT @ 320FPS WE WOULD BE ABLE TO DEAD SHOOT CENTER MASS ANYTHING FROM 40 - 60YARDS AS LONG AS WE WERE WITHIN A +/- ARE OF 5 YARDS ;D ;D MUCH AS I WOULD LOVE TO BELIEVE THAT .... WE ALL KNOW THAT THIS IS ABSURD. (I HOPE WE ALL KNOW THAT )The numbers are pretty insignificant at your typical hunting shots of 20 - 40 yards. A Whitetail Deer has about an 8” vertical kill zone, depending on the size of the animal and angle of shot. You can therefore shoot 4” below or above where your are aiming and still get a killing shot. At 30 yards only the 220 f.p.s. arrow will miss if you judge the shot 5 yards short. At 40 yards they all will miss if you judge it 5 yards short. ACTUALLY THATS NOT CORRECT EVEN BY THEIR OWN CLAIMS AT 40 YARDS THE 280FPS BOW WOULD STILL KILL AT A 5 YARD OVER ESTIMATION
I GUESS WHEN YOU ARE JUST MAKING THIS STUFF UP AS YOU GO ...IT'S HARD TO GET THE MATH RIGHT ;Doh....I forgot.... Since when have bows shooting 280 had +/- windows at 20 yards when given a 5 yard differential ?!

It never stops amazing me at these backporch brain surgeons and their claims, sure everyone has their own ideas and some are right or close to it and some are like this just plain old stupid.

It never stops amazing me at these backporch brain surgeons and their claims, sure everyone has their own ideas and some are right or close to it and some are like this just plain old stupid. This is the reason I say that the majority of bow hunting magazines and off shoots of those magazines are a waste of time Articles are written in large part by people who are staffers and use research to fill the blank pages before them or use that same info. to edit other peoples work For example.... A friend of mine is a propionate of the momentum theory and went to Africa (in part) to get material for a piece that he wanted to to submit to M.R. James (Bowhunter Magazine) for publication. The info. that he wrote was in large part eliminated from his piece Perhaps because it did not conform to Ashby's findings. What remained of his piece was a hollow shell with pictures of the hunt and one penetration pic. The funny thing was that the original text would have taken the same space in the magazine as to word count but it had words that they didn't approve of I myself had done a submission and it was rejected flat out because it flew in the face of Ashby's findings My piece had irrefutable evidence of application theory and it's changes when viewed on the smaller north American game species. To publish this documentation would have been to cast doubt on the blanket theory put forth by Ashby and therefore , had M.R. James agreed to publish , it would have put Bowhunter in the uncomfortable position of bucking the worlds leading authority pertaining to broadhead design and effect. Anyhow.... This is why I subscribe to the belief that if you really want to find the truth you have to get out of the box and find it for yourself

Politics........never have acquired a taste for them. They get in the way of the truth....LOL....seriously.
I read different outdoors-related magazines, and while there are some really interesting articles, I find that a portion of the supposed "information" is just cleverly disguised opinion or spin.....the percentages vary from publication to publication.
Glad I'm not the only one who feels this way..

You certainly are not the only one bowslap. There are alot of people here that can and want to think outside of the box
