It allows you to account for us that don't know their arrow speed because we've never had it tested. My stats are about the same as yours but, with adding the grains that are on your string and draw length, it shows my arrow speed as 227fps and 40lbs of KE

I have a maxxis 31, draw is 26 and poundage is 70. I shoot a 340 spine arrow with a 100 tip, my speed is 266. how do I know my KE?just used your calculator and it says i have 69 lbs of KE. Just to verify, 340 spine is arrow weight?

My arrow weighs 407 gr, and I shoot it at 265 fps.. Not bad for only having a 27" draw length.. I am not a speed guy though.. I would rather shoot slower, and be accurate then be one of these guys who needs to shoot 300 fps + and out of control.. Anyways, I have 63.48 ft lbs of kinetic energy to answer the question..
I like speed bows, therer a lot of them very accurate and speedy 300+fps
With that bow i can reduce draw weight to 60lb and not worry about penetration at all with a heavy arrow of course. I can shoot that bow daylong and not get tired.

I'm shooting the easton axis small diameter carbon arrows cut at 28'' from the valley of the nock. any idea what it might weigh?
28 inches x 9.5 GPI = 266 grains
Nock = 9 grains
Insert = 16 grains
Broad Head Adapter Ring = 5 grains
3 Fletchings 6grains each = 18 grains
100 grain Broadh Head
Total Weight Equals= 414 Grains.
Your Bow's IBO Speed is 323. Which means according to the program your bow is shooting your 414 grain arrow at 260.4 fps which give you 62.4 #'s of KE. Hope that helps.

WHO use trad. staff they do practice more and they know their limits, I don't think
that they will take 40-60 yard shot, which is in my opinion one of the most impotent
thing to now your/bow limits.
Compound shooters some will not think twice before taking a shot at elk at 60-80 yards
with out knowing their/bow limits, which is not good.
I'm absolutely agree that we need more worry about to know our/bow limits then KN

Hard to use a blanket statement like that. Using "traditional" or modern gear has nothing to do with how much one practices or knows their limitations.
Blanket or not but have you see trads taking shot beyond 30-40 yards?

Post by: Elknut1 on June 02, 2011, 06:12:55 AM
Yes, there are guys that can take deer & elk sized critters in the 40yd range! You have to realize that it's not the choice of equipment used here that is the issue! A longbow or recurve in the 55# draw wt. range with a 500+ grain arrow can easily take elk out to 60yds & more, it's got the umph to do it even with 3-bladed heads. The issue is at those longer distances that trad guys rarely ever use sights on their bows or peep sights so one could have that luxury. It's mostly all instinctive & that's tough to master over 40yds consistently! KE is needed but momentum is where the penetration is derived from!
Elk can be taken all day long with 35# of KE but I too prefer more when using a compound because I can! (grin)

][/quote]
I'm sure you did most likely at the rang probably, did you see some one was trying to take elk or deer
beyond 40 yards with trad bow? I don't think so, but for a compound bow shooters its pretty common.
Here is my explanation to that blanket statement ;
If you like to be successful with trad bow you have to stay in a good shape why?
because they don't use sight, release aid, stabilizer, arrow rest and so on and on....
we WHO ( i personally use compound bow as well ) shoots compound bow we have a huge advantage with a speed,sight,release aid,and on and on..............
I can take a brake for 3 month and then pick up my bow and shoot 6in group at 30 yard with out any trouble at all, please note its not because I'm good but due to my bow and accessorise, to shoot the same group at 40-60 yard not enough to have a good bow you need to practice.
Most game usually been taken under 40 yards, see this make some ppl been lazy and not practise enough but when the opportunity will be present to take a long shot they will take it due to high speed bow and nice equipment. I'm not saying that every one WHO shoots compound bow that they are lazy and don't practise no just some. Guys with trad equipment its a deferment crowd in my opinion, they use it not because they been forced but because they like it, they like challenge, and if you like it you will use any chance to go and shoot.

Nonsense. I actually own 3 recurves and have built a few myself. I shoot them a few times a year and even hunt with them occasionally. In a short amount of time after not shooting them for awhile I can be proficient enough to hunt. So called traditional archers are no better than any other archer. There are guys who hunt with "traditional" gear who don't pick up a bow until the week before the season too.
And yes, I have actually watched guys with "traditional" bows take shots at animals that they shouldn't have just like I have watched guys with compounds do the same thing. I personally have taken shots that in hindsight I know I shouldn't have. Luckily I had clean misses on those shots and learned something from it.

Z7 29.5 draw... 70 lbs....425 grain arrow.. How much? I dont know the FPS
Stats say up to 333 FPS, Have not chrono'd mine. Mine's similar setup with 70 lb draw. Shoot Beman MFX 300 (10.7 gpi) at 29 inches. 310 + 125 grain Muzzy Phantom = 435 grain. That would make KE 107.2 at maximum FPS. I might just be able to get my elk and my deer in the same shot...just have to get them to stand next to each other.
With that arrow weight you should be shooting around 290fps and 82ftlbs KE. 333fps would be IBO rating which is 350 grain arrow, 30" draw @ 70lbs.

This calculator has a shot angle distance calculator that confuses the h*ll out of me. I understand that if "Straight Line Distance" is 28 yards then the horizontal distance is 20 yards at 45 degrees, but why would the aim point be for 14.1 yds???? In my little pea brain, the aim point should be whatever the horizontal distance is.

I shoot a 150gr broadhead (Alaska Bowhunting Supplies - Masai). The extra weight forward helps stabilize the arrow faster (more accurate) and nothing but full pass thru past several years on Elk, deer, bear!!!
