    Question Another noisy bow - please help

    So, I've been shooting for a while now with a Core Air Riser, and SF premium limbs, 20lb @ 68", wound up to 25lb using the bolts on the riser, and the set-up has been very quiet.
    I've now changed to WNS Premium limbs, 26lb @ 68", with a new string, and it makes an unbelievable amount of noise when I loose. Not a nice quiet thrummm, but more of an incredibly loud TWANG.
    Nothing else in the set-up has changed, and everything is screwed on as tight as it possibly can be.
    In order to get the limbs to actually pull 26lb on the finger, (I'm just not strong enough for any more than that yet) I have had to loosen the riser bolts quite considerably from where they were with the SF limbs, and it occurs to me, as I type this, that this could be the source of all the noise. I'll hopefully be going down to a quiet range over the weekend to do all the usual talcum powder on the limbs business, and my ultimate aim is to gradually tighten the bolts back up again to slowly increase the poundage, but what else should I look out for?
    Please help! The arrows are still going where they're meant to, like bullets at 20 yards into the gold, but I don't know enough yet about bow tuning to know what else I should look at. I think that the noise 'shouldn't' matter if the arrows are going correctly, but I really don't want the whole line to stop, look at me, and go 'Jesus! That's loud', which happened several times last night. Especially when we go back indoors.

    Same arrows? My guess is they are now too weak and the noise is them striking your riser. Have you fletching damage, cracked nocks or marks on the riser, shelf or rest? (That's what the talc is for, not the limbs) What is your centre-shot like and how stiff is your button?

    Ooh, I didn't think of that. I hope not, they're brand new and were expensive. They are in absolutely immaculate condition, but I have noticed that there is a rubbery residue on the shelf. I didn't know what it was, and cleaned it off a fortnight ago, but now it's back, so maybe that's it. It is right where the vanes could conceivably be hitting the shelf. I guess I'll try the talc on there at the weekend. I'm not sure what a centre-shot is, and how do I measure my button stiffness?

    Button stiffness - squish it! If your arrows are now on the weak side with your higher poundage, faster limbs you *may* be able to compensate for that by stiffening the button a little. However, it certainly does sound like you have contact with your fletchings and the bow and you really need to look at your nocking point position and tune. Maybe someone in the club can help?

    Aslan, you're a star, thank you. I'll let you know how I get on with that. I really don't want to have to replace the new arrows!
    I know that it's a very long list of things it could be, any more suggestions?
