    From the chart you are well above the minimum recommended. I sounds like heavier arrows will drop your speed and not have as flat a trajectory, but might have more Kinetic energy for penetration. I am not sure if just a different broadhead would have the same result but keep the trajectory and speed of the lighter arrow.

    http://bowsite.com/bowsite/features/...r/penetration/ For the KE calcs. I guess you need the speed of the arrow, so you can compare that way. You can play with the calculator deal on this link, but if the heavier arrow drops your speed you end up with the same or less kinetic energy, but not as flat a trajectory, so no advantage. I am not really sure, just some stuff to look at. The arrow construction and stuff are some other things to look at it sounds like. It could be a good debate.

    I'm shooting Beman ICS Hunter 300s. 65lb, 29.5" draw, 420 gr arrow. The latest Eastmans Bowhunter gave a recommendation that if shooting a fixed blade bd, you can shoot a stiffer spined (heavier) arrow. Shooting thru the conograph a few weeks ago my KE was 83.

    OK right now i shoot the Easton axis 400. And i was thinking of trying to get a higher FOC by going to a stiffer spine 340 and either getting 125 grain broad head or adding two inserts up front?

    Holy cow 83 ft-lbs? That is pretty good. I might be a little light on my arrows. Thanks for the topic. I might have to look at getting some stiffer spine jobbers myself. I prefer fixed blade, no good reason it just seems more sturdy to me. I figured my arrow to be (didn't have a scale, might go into the shop tomorrow) about 410 grains with 70# of pull and 31" draw length. I have never shot a chrono, though. Thanks

    Might need to go .300 spine. I would say you are underspined with the 400 spine. I am shooting 72lbs and 27.5" draw and need to run a .300 spine arrow.

    I would go with a 125 gr head on a .300 spine if I were you. No more than a .340 spine. .400 is a little weak for your DL and poundage.

    I shoot a Mathews Z7, 70lbs, 28" draw and my arrow weighs in at around 475 grains. I shoot Easton pro hunter 340s 125 grain broadhead with blazer veins. I can post a video of me shooting them at 100 yds if you want. Truly a great arrow. Mark

    453 grains here with carbon express pile driver arrows cut to 27.5 inches at 70 pounds. 100 grain broadhead and 40 grain insert on the front... these things fly like darts! I'm shooting almost 290 fps and won't be changing my setup for elk this year
    Now therefore, please take your weapons, your quiver and your bow, and go out to the field and hunt game for me.
