    My Bow Specs are: Mission Venture 30 inch DL. 64 lbs DW.

    My Arrow Specs: Goldtip XT Hunters Lost Camo with 2 inch Blazers. 5575. 10.2 grains per inch.

    I shoot 125 grains is the Broadhead I'm using.

    If I need to post more information let me know.

    Thanks in Advance.

    Without running the numbers on pinwheel, I'd say you are very under spined. I'm thinking 340-300 spine

    Your probably pretty close. 100 grain head would stiffen it up a little. Do the muzzy s fly good?

    The muzzys do not fly well at all. That's why I'm wondering about my spine. I had my bow paper tuned today and the field tips shoot nice in a group and my broadhead shoots about 8 inches low and to the right.

    Can't do it right now but might be able to run your set up on pinwheel to see the best spine. You might be a little weak which would make fixed blades hard to tune. Try turning you draw weight down to 60 lbs. but there may be more tuning needed after the spine is correct

    Ok this may sound dumb but it sounds weird to me that my spine is a little weak and I would have to turn my setup down? Is my poundage set to high for the strength of arrow?

    Is it equally low and right, or more low or more right?

    Are you shooting the same BH & arrow each time, or different ones? Have they been spin tested?

    **EDIT** scratch what I said. I'm finding two spines for 7595 XT hunters, .300 and .340.

    PM tfox :tu:

    This is one of my pics when I originally discovered the problem. Broadhead test.jpg Today when I shot my bow after the paper tune it was very similar.

    Also I did do a spin test on the bhs. They seemed fine.

    I pm you back but just thought of something.

    Get centershot set first, with either walk back or french tune. Don't worry about paper at this point. Once you have centershot, then CHECK through paper. If there is a tear, you might be torquing the bow or you just need to twist the yoke on the tear side until it is gone.

    This should get the brosdhead very close. You might still have a spine issue with the arrow being that long. The broadhead will still impact right if you do.

    If so, I suggest trimming a little off the back end of the arrow if you can and refletching.

    Big question does it shoot low right with field tips?

    Muzzy's are fine if the bow/arrow combo are tuned properly.

    Okay you're speaking a foreign language to me now. I don't know what french tuning is and I've heard of centershot but not too clear what it is. And if i twist the cable on the yoke does it matter in which direction I twist it

    The yoke will need to be shortened on the side it is tearing. Right tear = twist right yoke to shorten it. Look at the direction of the twist and make it tighter. (Add twist)


    Just walk back tune or do a search for french tune.

    Centershot is just setting the rest to be in the center of the cams direction when fired.

    You are right muzzys are fine...... If you shoot a bow that shoots under 270 fps! I've owned a bow shop in my town for 10 years and I've had at least 25 people with same issue bcuz back in the day muzzys where hard to beat but newer fast bows do not shoot a fixed 3 blade broadheads as well as a slow bow that don't need as much tuning. Newer bows will spin an arrow faster and a three blade fixed broadhead causes lots of drag! I'm not a know it all just telling you my experiences
