Yeah, I totally get heavy arrows for larger game but, even though bows become more efficient with heavy arrows I seriously doubt that they will defy a fundamental law of physics. Sent from my iPhone using Tapatalk
Also you are very correct about 650 being close to optimal. My set ups momentum peaked right at 640 Sent from my iPhone using Tapatalk
You should remember that composites (carbon fiber etc.) are a whole different set of calculations and has its own rules.... Most of the very seasoned guys here rather shoot heavy arrows above 240ft/s and hunt everything with it. The difference in stringjump movement is so small between a 300ft/s arrow and a 240ft/s arrow that the quieter 240ft/s arrow is mostly better off than a "noisy" fast one.
Makes sense, I just like my 450 grain arrow as a good blend of weight and speed for whitetails. Sent from my iPhone using Tapatalk
I'm sure there is but I have yet to see that point. It is well above 1000 gr from the "controlled" testing I've seen done. Sent from my SAMSUNG-SGH-I317 using Tapatalk
I think it depends also on what your hunting and can it jump your string? I just bought some Easton Dangerous Games that weight in at 683gr but these are for big hogs only. Elk and whitetail I shoot 425gr Bemens hunters.
Quite possibly, it's been a year since I took physics. I'm a little confused, are you saying because they heavier arrows are more efficient and the calculators don't factor that in, they are actually shooting faster? Or are they just retaining energy/momentum more? Sent from my iPhone using Tapatalk
The normal calculators dont factor in that the bow is more efficient with heavy arrows. If I use my setup on the calculators I am about 10% faster measured than calculated.
That's what I figured. Most likely I will move to a 500+ grain arrow. I just feel like 650 is a little overkill for whitetails. Sent from my iPhone using Tapatalk
So do you think my arrow is fine for whitetails? If I go to a 50 grain insert I will be at about 477 with a little more than 15% FOC Sent from my iPhone using Tapatalk
It doesn't take much for whitetail and my honest opinion is that the broadhead plays as big of a role or bigger than arrow weight. I also believe high foc is more advantageous than just overall weight. Most arrows designed for hunting are plenty heavy for whitetail. Penetration has so many variables that it is impossible to quantify what is best. Tune and cut on contact heads will yield great results on whitetail regardless of arrow weight. I personally shoot a 500 gr arrow with 19 1/2% foc with cut on contact magnus buzzcuts at 57# @ 28" draw. No issues here. Sent from my SAMSUNG-SGH-I317 using Tapatalk
I haven't seen much difference in high foc advantages until the 19-20% range so adding 50 gr to reach 15% is probably a wash. Add the 50 to the insert and add 50 to the head and there will be some real gains. Or just add 100 to the insert. Sent from my SAMSUNG-SGH-I317 using Tapatalk
I posted a couple months ago asking how much weight is to much for arrows for this reason. Pretty sure Im going to try this challenge out if I can afford it in a month or 2. Been wanting to. I only hunt whitetails, but i want the most penetration possible for the risk of things like shoulder hits. My bow is pretty bad a already, but dont hurt to upgrade. Might also do like someone on here posted, and have both a light arrow and heavy arrow pin set up...thats a cool idea!
maspetros, if you go to the website you'll see that they are not just for whitetails, but they have had complete pass throughs on elk, moose, and grizzly. Also when it comes to the speed loss thing there is a video that proves there is not that much speed loss.
Using a prototype bow back in 2003. It shot a High Country Speed pro arrow 310 gr. with a Grim Reaper 1 3/8" razor tip included, 240 fps.. At 28 yards It got a complete pass through on this bear and stuck in the ground. If you are hunting N America big game, 50# ke is plenty on a well placed shot. Speed makes up poor yardage estimation which can improve the shot placement.
