    So my 11yr old daughter has had a bow for about 3 years now. She currently shoots 30lb draw wieght from a Diamond Edge bow. The arrows seem to make pretty good speed and she is a good shot out to 25yards. We are eventually going to get new limbs that would let her get up to a 40 lb draw wieght. In my state there is no min draw wieght or arrow speed regulations. With todays technology arrows are flying faster out of bows than ever before. So what do you think a good arrow speed would be to start bow hunting? Should I get her some small broadheads and see how much pentration we get into the target? What say you? She is reallly hoping to be in the treestand with her bow this year.

    If you can get her to 40lb pull and a draw around 23"+ get her some small diameter shafts and cut on contact broad heads like magnus around 90 grains to 100 finish weight at 255 grain she will be kill'n deer at 25 yards. She what her arrows weight now and crono them at your local bow shop so you have a base before you change those limbs. I see nuggents name on your info ,his oll lady shot 40 lbs for years and may still.

    Getting the base speed and actual arrow wight is the easy part. Her draw legnth is at 23.5" already. We both shoot small diameter arrows and she will be using an 85 grain broadhead. What I am really looking for is recomended arrow speed or kkenetic energy the arrow weight 280.8 grains including broadhead. The bow is twin cam and 6.5 riser hieght. The 40 pound rule of thumb is becoming pretty out dated with todays technology.

    Sounds like your on the right track an beleive 40lbs. will do the job well...but...shot placement is very important. You will want a good rib shot behind the shoulder or you won't penetrate to the vitals. I believe your arrow will probably not pass through, but this can be very good because as the deer runs an hits branches it will move the arrow an the broadhead around inside cutting even more. I started out with only 50 lb. Darton compound, never got a pass through with it, but it did a great job as long as I made good shot placement. I'm sure with good shot placement that 40lb. will do great

    I added arrow weight and brace hieght. Draw legnth has been there. The huntersfriend site seems more like a catalog. The only info I could get there was a comparison chart. So maybe I need to re phrase the question. My kid has a 23.5" draw legnth, her arrow is 280.8 grains, brace heigth is 6.5 and bow has twin cams. How fast do you think an arrow with that wieght should be moving before it could be considered an effective speed for hunting? I started with a 40lb bow 20+years ago surely todays bows are much more effective than back then. I know that shot placement will be number 1 concern.

    It was your old bow? ok if the company is still in buisness there tec guys . Maybe they can help with the info you need. If your putting on new limbs maybe they can cobble up some new cams or wheels that will help too.

    To answer the bottom line on your question, somewhere in the 235fps range should suffice. This is simply based upon the info you have, and the chart on the lower listed Huntersfriend link and using the Bowhunting Safari KE calculator.

    Here are a couple of links that you might can use, to help you get a ball park idea of the energy or your daughters rig.

    http://www.sonoranbowhunting.com/calc.htm

    http://utopiaprogramming.com/ke/KineticEnergy.html#

    http://www.bowhuntingsafari.com/html/kinetic_energy_calculator.htm

    Also I know you said it seemed useless, but here is a useful article that should help out when you find the actual speed your dealing with,
    http://www.huntersfriend.com/2007-Carbon-Arrows/arrow-selection-guide5.htm
    I am not sure if this was the one you referred to or not.

    For the calculators, I like the last calculator because it will allow you to put in the KE your wanting, and the weight you have and it will give you the speed necessary to get it. This makes it pretty easy to set the bow up for a range by simply adjusting the pull to get the desired velocity with the chosen arrow. For the most part, generally speaking, if your pushing somewhere in the 45-50 range on KE with a good cut on contact head your in business, provided she can get the shot placement in the boiler room.

    Try to get some arrows across a chronograph so you have the speed. Until you get that your simply guessing. Once you get the speed, try to get in the 35-40lb range and you should be good. I would not try using anything mechanical as they take away energy and momentum that she is already working to build up. You also might be able to squeek up the weight of the arrow a bit by going with a 100gr head, and get more downrange punch with out having to add too much speed to it. If they will still shoot accurately it is definitely worth the try. There are numerous 100gr COC heads that should work for her.

    My friends wife is in a similar situation. She is shooting 40# with a 25 1/2" draw. We started her out using the Magnus heads. However, after getting a bent point on several we changed over to some of the shorter thicker bladed heads. She is getting full two side penetration, but not complete pass through. In other words not sticking the arrow in the ground behind the animal. The best heads we have used so far are Razor Tricks, CE-XT 4-Blade, Eastman Firstcut XT 100, Magnus Stingers 2 blade.

    I hope this helps, I know how frustrating it can get trying to get the details down on things like this. Try to get her out on some hogs. If she can get through them, deer will not be an issue other than hitting where she aims. Good luck to the both of you, and remember, placement over all else will seize the day.

    Thank you. I am going to book mark this page so I can find those links again. 235fps seems reasonable I really doubt that we are quite there. We did shoot a little yesterday, and she is ready for the new limbs (30-40). I bet she can get up to 35 lb draw or so and still shoot correctly. We will get her chrono'ed then. As far as arrow wieght goes I was thinking about getting her into 100 gr field points, broadheads later, and really could probably bump up her draw legnth a little and shoot a little longer of an arrow. Dang kids grow fast! We were looking to go late season at best, I think maybe we will hold of until after deer season and chase some hogs first. From here I go play with those calculaters and some arrows and see what we can achieve. Thanks again everyonde.
