Scott,
I have a Stallion as well. It has 48# at 28" limbs on it. My draw length is 31". I admit it is a little noisier than my 40 year old Bear recurve, but not much. Are you getting bow noise or arrow slap on the riser? Bow noise could be several things you can fix; arrow slap is a spine deal, not a bow deal.
Mine does have the sheet-cork "gaskets" under the limbs. I make sure the limb bolts are SUPER TIGHT when I put the bow together. You might unstring and make sure yours are as tight as you can get them by hand.
I have one set of the rubber cat whiskers on the bow and the adhesive foam/felt padding on the limbs (actually as I sit here looking at it, I think it is the fuzzy part of wide, heavy duty, stick -on Velcro). I shoot the string that came with the bow, some type of "fast flight" type material endless.
Like Ray's Quinn, mine likes a brace height a little higher than I am used to, about eight inches. I don't have any mushrooms or other deadeners on the bow. I also shoot off the shelf.
Okay... I know this sounds crazy and I have no other proof other than my own ears, BUT I put one of the adhesive leather saddles on the grip; the bow seems quieter. Hard to believe I know, it could just be in my head. The bare metal grip was a little slippery for me and is WAY cold in the winter, so I put one on to help with that. Again, sounds ridiculous but I could SWEAR it quieted the bow even more.
I don’t shoot the bow with any quiver or other stuff attached. I carry my arrows in to hunt with a Boa strap-on but take the quiver off to hunt. In a blind I just lay it aside; in a tree stand I always have a hook to hang it on close at hand. A quiver attached could add to the noise factor.
Bottom-line: Check to see if you have the sheet-cork gaskets under the limbs and make sure the limb bolts are as tight as you can get them by hand. Look at your brace height and try it at eight or more inches. Remove any attachments such as quivers or the like and see what that does for you.
Here is a picture of my set-up. If these suggestions don’t work or you have already tried all this, holler back and we will figure something else out. The Quinn Stallions are great bows! I sure love mine.
OkKeith
