    Is it possible for me to get to 300 total grains using the 250 Carbon Express Blue Streak Maxima? I calculate the following:

    28inch arrow X 7.4 grains/inch = 207

    Blazer X2 vanes = 12 (four each)

    glue in point = 82

    nock colar = 4

    nock = 10

    This adds up to 315 plus glue weight. I figure in real life I will be around 320. The above uses 82 grain point. Is this too light to provide good FOC?

    My Creed will be set to 60 ilbs. My calculated DW is 65 lbs. Draw length is 28.

    How can I get to 5 grains per lb? These arrows will not be used for hunting.

    Run the numbers through OT2 for some general idea. You should be able to get close to 5 GPI if that is what you are looking for and some arrows that will give you a 8-10% FOC which is OK for 3D. Carbon Tech and Victory both come to mind for a lighter arrow with a better FOC.

    check out http://www.blackeaglearrows.com/ as another source to get you
    down to that 5gr per lbs that you are looking for.

    very nice products and great service to help you get what your looking for and what will work for you.

    contact them with your setup and what your wanting and they will give you your chooses.

    Hope this helps you out cause they helped me alot with my setup.
    I like to shoot one arrow for both 3-D and hunting and with my MR7 at 29.5/70 it takes a stiff shaft to handle it. my setup is a 28.5″ carnivore .300 shaft 8.5gr per inch with light weight nock and inserts,NAP quick fletch with 100gr points total weight is 395gr.

    Thank you sir! Wow, that program is great! For fun, using simulation tab, I set estimated to 30 and visual to 40 and changed arrow speeds. You can see how little 20fps makes on impact.

    Thanks again! =D/>” title=”Applause” /></div>

    I just dont get it when everyone tries to shoot arrows on the minimum weight. I want arrows that are strong, tough and will be consistent. I bought 6 Ultralite X cutters and all were built in about 10 minutes, (pre fleteched shafts) all were within about 6 grains, all grouped side by side oron top of each other through my Parker Buckhunter set at 55lbs 27 in dl.
    I bought 12 more when I got my black limb XT and those were all within 5 grains. I just dont see the reasoning. My XT would chrono within 3 fps through whole dozen. and faster ones were heavier ones.
    I see guys slinging light arrows, and having so many issues.
    Guess I prefer consistent over trying to get the fastest fps.

    For 3D, I’d recommend a better arrow than the CX Maxima Blue Streak. If you want to stay with Carbon Express, the CXL-Pro with its larger diameter will give you a scoring advantage, also for Indoor spots.

    28.5″ CXL-Pro 250, 70-gr Parabolic Point + 20-gr wt, pin nock adapter and Soma pin nocks, Bohning X2 vanes.
