    Im shooting a Mathews z7 at 60lbs and Beman arrows Beman Ics Hunter 400 Watching the arrow it seems to flutter just before hitting the target is this normal? I am using a whisker biscuit with cock vane up. I also have the same results shooting at 60lb with my K&k Vengeance same set up same arrows. Appreciate any comments.

    In short, no that's not normal.

    In long, there's a million and one reasons this could be happening.
    -Bow torque
    -Rest contact (just make sure you're not hitting the black whiskers with your fletching)
    -Wrong arrow spine
    -Poor rest alignment
    -Poor nock indicator/string loop placement
    -Nock pinch

    Start here, read through it all and come back with questions. We'll work you through it.

    It appears to be the arrow. I just bought these a few days ago the Ics Hunters 400 I have. A few Ics Hunter 340 and they shoot perfect. Damn just wasted $100 I told him I had been shooting the 340 but he said I should be shooting 400's.

    What are your spec.'s for draw length and point weight? If your draw is short and your point weight is light then he was not incorrect. Remember that changing arrow spine is going to cause you to have to retune your set-up. A properly matched spine is going to allow your rest to remain closer to center shot when the arrow is leaving the bow straight and true. It may just be that your rest is offset to make the 340's work. They may not be the best arrow though. There are a lot of variables at work here. Changing one effects all the others.

    My draw was 28 1/2 shooting 125 grain. Im not sure if this answers the question I am new to archery so youll have to forgive my ignorance when it comes to this.

    In your shop guy's defense, that puts you somewhere on the edge between the 340 and 400 selection (depending on your actual shaft length). He wasn't wrong in saying that the 400 would work for you but, in my opinion the 340 is the better choice. I say this because the Z7 xtreme has a little more aggressive than average cam and, as a rule of thumb, when on the edge of two spines you go with the heavier spine for hunting. (Stiff shafts handle broadheads better than weak ones.)
