RE: Speed or KE?
 

I personally want both but try to reach a happy medium. I am shooting a setup that shoots a 469 gr. arrow @ 275 fps. and for me that a pretty good mix of the 2.

RE: Speed or KE?
 

I never thought these 2 variables were that mutually exclusive. Eeking out a few FPS is probably moot when comparing the KE differences. And vice versa.

That said, I like momentum. Give me a lil heavier arrow going a lil slower and I'm fine. My shots aren't normally very far, I want all the momentum I can get to drive an arrow into the vitals from any angle I need to.

RE: Speed or KE?
 

I will be shooting a 402 grain arrow at 273 FPS and getting about 67 ft lbs of KE. All out of a 61 # bow at 28 " draw.

I am making sure I got what it takes in case Brookfield Zoo looses a few animals;)

RE: Speed or KE?
 

Neither, I want momentum. Regardless of how fast your bow is different weight arrows will normally fall in the same KE range providing you don't change the draw length or draw weight. The difference between a lighter faster arrow and slower heavier arrow has more to do with momentum than it does KE. The Heavier arrow will carry that energy farther, where as the lighter one bleeds off energy faster.

Oh, and to answer your question, I shoot 450 grn arrows at a little over 200 fps on a bow that I could probably get 270-280 fps out of with lighter arrows ( I have a short draw).

RE: Speed or KE?
 

I would have to say speed, but I think 280 fps is plenty fast enough with my 403 grain arrow. I like a balace of speed and KE. If you look at the numbers, heavier arrows don't providemuch more KE. It is usually less than 5% so becareful how much you trade off with those heavy arrows.

here is a good calculator to determine KE, arrow drop and momentum

RE: Speed or KE?
 

I polled for KE, as the only reason I would need to know the speed is to figure the KE.....AS said before momentum is what I look for (which kinda goes hand in hand with all of them). I tend to adjust the weight of my shafts to get the most everything I can out of that bow.I have always went with a little heavier arrow (weight tubes) versus the light weight arrows, yeah you loose a little speed but you dont have arrows penetrating the sheild of a hog barelyan inch...(One of my buddies done this back in the day with some light easton acc's that he normally used on the 3-D course). I have light arrows but they don't get used except on the 3-D range and I use them there for speed (flatter trajectory), less error....I don't use anything in a hunting situation less than 400gr....

You know what they say, short draw.......jk:D:D:D:D:D
