Ladies, what you really need to understand about draw weight/kinetic energy, etc is the weight to power ratio of your bow set up....
HUH??????
It all comes down to the weight of the arrow you shoot....... Lighter arrow, more speed; more speed, more energy.
That said, a heavier arrow will generate more kinetic energy too, but at a slower speed.
Women hunters will do better with more speed and the reason is if you make a boo boo in range estimation, then chances are you will still make a kill shot because the arrow will be flying flatter to your sight line.
This next comment is for the gals who are pulling lower poundage....ever wonder why you can't get enough elevation out of your sight for a 3rd, 4th or perhasps 5th pin?
Well there ya go.....too slow an arrow.
The industry rates the speed of the bow (IBO) with a 350 grain arrow; 30" draw length @ 70 lbs.
Most of us will never see those numbers....ever!
But if you stay within the magical 5 grains per pound of weight, you can make your bow really perform.
For example....a friend of mine shoots a Bowtech Equalizer.
Here's her set up:
34 lbs but trying to get up to 40#
26" Draw Lenght
Arrows...Gold Tip Ultralights 600's...weight....224 grains.
We just shot her arrows through the chronograph and guess what........249fps!!!!!!!
If she ever reaches 40 lbs, her speeds should be in the high 260's
When I set her up, we made sure the weight of the arrows would not go too much over 200 grains.
To competely match up her bow to arrow, the weight of the arrow could be 170 grains....that's real light and probably not possible to obtain, so the set up will be just a little heavy when she reaches 40#.
The point is, next time you are in your archery shop...take out one of your arrows and weight it. Then take that number and divide it by 5.
The resulting number should be close to the amount of poundage your pulling. If it isn't, try to figure a way to shoot a lighter arrow.
your 3-D scores will go up and you'll be able to make longer more accurate shots.
One more factor effecting speed is the length of draw.
Gals who have short little stumps for arms like me don't get as much mechanical advantage from our bows because the arrows doesn't stay on the string as long as it does for the longer armed ones.
So your 50 lbs will be more efficient than my 50#.
I compensate by for that by pulling more poundage and shooting the fastest bows I can afford.
Thank God the industry offers many great bows and now lighter arrows like the Gold Tip Velocities.
Hope this help
By the way....I pull 58 # @ 25 on my hunting bow
54 # on my 3-D bow
45# on my indoor 5 spot bow
