        OK, I love building and shooting wood arrows. I also know how importand a good FOC is.

        I would like to get some advise from you wood arrow builders on how to achieve a good FOC?

        My hunting arrows not are 50-55 spine parallel Douglas fir shaftes. Cut to 28″ with 145 gr tips. I am getting about 8.5% foc.I know increasing the front weight will help, say 160gr, but I am getting 150 fps now. I am not sure I want to go slower just to get a better foc.:(

        I do use wraps, I will stop doing that now!

        Should I go to a tapered shaft?

        A little help/advise please.

        I really want to keep shooting woodies.

          Your arrows are 50/55 ok, but what about your bow ….

          Self, LB or recurve center shoot or not ? fiber or carbon or self bow ?

          Draw weight ? and draw lenght ?

          Also interesting to know bare arrow weight ……..:roll:

            OK, my bow right now is a 51 @ 28. 58″

            It is a Striker reflex deflex long bow.

            My draw is 26.5″

            I know my arrow weight 525 gr built.

            5″ trad cut feathers.

            Dont get me wrong, the arrows fly great!

            Just looking to increase FOC. I still want to shoot wood.

            I love making them.

              Well Jason you are about to get the advise of the experts. Check out the Ashby forum and read the reports. As I told you on our shoot Sunday past–woods look great–but when hunting we owe the prey the most ethical kill we can do with trad gear–and from my limited knowledge that means carbons with 28 to 31% Efoc.

                I hear ya mike.

                I’m thinking tapered shafts no cap wraps and 160-200 gr tips.

                I’m thinking it will get me close to 20%.

                I agree. The animals we hunt deserve our utmost respect.

                  Wojo — If you use the right spine arrows you can get your FOC up a good deal by going with heavier heads and, yes, tapered shafts. However you’re still well below Ashby recommended minimum arrow weight for assured penetration of heavy bones, 650 grains. If forced to a choice, I’ll go with total weight over FOC any time. But you can get most of the extra 125 you need simply by going to heavier heads and slightly heavier shafts, and likely increase FOC while you’re at it. Eons ago, when I first read Ashby’s early Natal Report, which did not get in to FOC but focused on arrow weight and broadhead design, I immediately started shooting plumb through elk, first time ever. My arrows were hickory and weighed in the 840s and the heads were only 125. My FOC must have been near 0. So right or wrong, my advice is always to get the 650 first, with as much of it up front as possible, then think about improving FOC. As Mike suggests, carbons make arrow lethality thus ethics easy. But I sure understand your wood love and am a victim myself. Experimentation with various arrow shaft materials and point weights is great fun and worth the investment in itself.

                    Thanks Dave!

                    As a siege note, I ordered 3 of your books today!

                    I have some reading to do!

                      I meant side note!:x

                      So, 650 total weight.

                      I would prob need to go up a spine.

                      55-60 tapered. I will get some fro me Surewood to try.

                        51 @ 28 must be around 42/44 Lbs at your 26 1/2 That is to say you shoot something like 12 grains / Lbs

                        If you hunt very heavy game that can be good, but you must shoot very close

                        On an other hand spine selectors for wooden shafts are the same from the old time when bows were only made with wood

                        To day with moderns bows you should choice 61/65 wood shafts

                        And find a better balance between straight fly and arrows weight

                        I killed european wild boars with 9 grains /lbs and 420pounds bear in Canada with 2117 alu and 125 grains Zuikey broahead

                          My shafts now are 520 gr. (50/55 spine)

                          I did get good penitration on a 200 pound bear this spring.

                          I hear you tho. Thanks for the advise.

                          I am working up to a heavier poundage and heavier arrows,with more FOC.

                          I am shooting for 55 pounds at my draw. I would like to get arrows around 650 gr with at least 20% out front.

                          At least this is what I am shooting for this fall!

                          my 51# with a little more FOC should still be ok on the white tails this fall????

                            Bears are very little resistant to penetration and have very thin skin

                            45 Lbs with 400 grains arrows are enough for a 250 Lbs bear

                            In order of importance to have a fast and clean ( human ) kill

                            1 / Presicion Kill zone

                            2 / very sharp blade

                            3 / single blade

                            4 / arround 10 Lbs / bow poundage

                            You can get penetration with single bevel blade

                            without add to much weight

                            One of my friend killed 3 african buffalos with Dwyer LB set @ 65 Lbs and 750 grains arrows

                            His secret : he never shoots @ more than 12 meters !

                                Ok. I went ahead and put 200 gr on front of my existing shafts. I am around 625 total weight and around 14% FOC.

                                They shoot good.

                                Now, dare I ask…..what about speed? I know speed is overrated. But is there a min speed to try and achieve?

                                  I would say that with perfect arrow flight, arrow mass will trump speed every time.

                                    Ok, a general question. Regardless of arrow material. I know Dr Ashby’s min weight is 650gr. But at what speed you need to shoot it at? I eventually plan to hunt elk. So I would assume a 700-800 gr arrow would be better. Do you need to shoot this heavy of an arrow out of a 60-75 pound bow? Or will 50-55 pound due? Assuming the arrow and bow are tuned together of course.
