The faster the arrow the more KE you can acheive...KE of the arrow determines the penetration momentum is very close to the same thing.....when the arrows moves at 340fps at 350gr then it will move at 315 at 400gr which gives more KE...KE doesnt make the arrow faster =[] http://bowsite.com/bowsite/features/practical_bowhunter/penetration/index.cfm
Sorry, but momentum determines penetration. http://tradgang.com/ashby/Momentum Kinetic Energy and Arrow Penetration.htm
The more KE you have hitting the animal the further it will drive the shaft into the body... so will the momentum....and KE doesnt make the arrow faster....
Not trying to be ignoratn or arrogant or anything.....but Say i swing a baseball bat 100mph and it weights 33oz I then swing it 80mph and it weighs 33oz Which ball is going to go further? This is called KE....
I thought we were talking about penetration not distance. Do yourself a favor, read the link I posted, here's an excerpt:
Young fellow, I really don't care what you believe but, I do care that other folks visiting this forum get the correct information.
Well im here to learn...im not being a jerk...we are just discussing...im trying to figure out what i believe so i can get the maximum performance out of my rig. I was just going of the common sense i had...guess i was wrong....good discussion i did win one part tho =] time for me to go to bed goodnight...thanks for the info The more KE the more momentum...which means more penetration?
OCT......I'll tell you the same thing I tell everybody..... WHen Bruce says something about archery (esp. the technical aspects of the sport).......do yourself a favor..... Back away from the keyboard and reach for your notepad. Carry on.
i like discussing the matter even if hes right because when you oppose...you get reasons that would have never been told..thanks for all the help guys!!
Here's the problem. Sure, more wieght can be good. But 95% of the time, it makes people not reach thier full true draw. I see it over and over. I was reminded of that myself. I am finishing an osage bow. I thought I wanted a 60lb osage bow. But stretched out, I have a 29" draw. But clearly from this picture, I am not reaching that draw. I am short drawing and don't even know it. That arrow is a 28" arrow http://i301.photobucket.com/albums/nn73/bigcountry_ky/Osage4/Fulldraw1.jpg Now, I am at 57lb at 27" now. I think I learned its more important to be at my full 29" and at 55lbs. A light bow brought to full draw will outperform a heavy bow short drawn any day of the week.
BC, as the event nears in May I will keep you updated. I will swing by and we can link up for a bit as this will be my first trad event. I just want to walk around and shoot bows until I can find one that fits me.
Here's something for you to think about. Traditional bows and KE do not go together. It's merely Impossible. Reasons are traditional bows hardly break the 200 fps mark. What's a person do then, you weight up your arrows and go for the momentum thing. Ever heard of a traditional bowhunter shooting 350 grain arrows? I haven't. If he/she did their not going to get much penetration with the speed they gain In the light arrows. In saying what I just said there Isn't nothing wrong in the least with shooting a heavy pounded traditional bow. If you can handle It and your form doesn't suffer, who are we or anyone to say you shouldn't. If your new to traditional bows, then by all means you better start out In that 40lb range. I also shot traditional bows like you at a very young age. I was shooting recurves and longbows at 3 years old. Once I hit 12 years old dad bought me a compound and said you get a few under your belt with a compound and then maybe you can shoot a recurve like your dad. I hunted with a compound right around 10 years or so I think It was and then one day I said I'm done and went to a traditional bow. This recurve I went to was suppose to be 65lbs at 28 Inches. It ended up being 73lbs at 28 Inches. Even though I had shot traditional bows all my life the heavy poundage In this recurve ended up hurting my form about 5 years Into shooting It. Like bigcountry said, I started short drawing by about an Inch without even knowing It. I fixed It but wow did It take some work. Still 10 years later I catch myself short drawing once In a while. It was a tough thing to break but I eventually did It. I'm still hunting with this same recurve today. It's on It's way to the wall one of these years though being my limbs are wearing out or going to heck. It's lost 15 pounds In draw weight since 1995 when I 1st got It. 2 years ago It lost 12 pounds over winter and last year again It lost 3 pounds over summer.
