I bought some Carbon Express 300 and a whisker buscuit today. I have been shooting CX 200 at 25.5 inches out my Outback at 64 lbs.- 28" with a Muzzy zero effect. I fletched the CX 300 with Duravanes with a little right helical and cut them to 27.5 inches. Installed the whisker buscuit. Shot it through paper at 5 steps and got a bullet hole. Moved back to 10 yards, then 15 yards and 20 yards. Got a bullet hole. Moved backed to about 10 steps just to check. I got a 3/8" left tear several times. This is kind of puzzling. I am not sure whats happening but will shoot some more tomorrow. I noticed the buscuit was a little noisey on the draw and seemed to have a little noise on the shot. The jury is still out on this rest. It seems to shoot well but I will need several more outings in the yard till I take the stud that holds the Muzzy off the bow. This is the new buscuit with the adjustments and the brown and black whiskers. If anyone has some ideas on the left tear and noise, I'm all ears. Don
