I wanted to try a biscuit on my new NoCam bow. I had an old biscuit medium size lying around so I put it on. I'm shooting Carbon Express 250 shafts. I checked and can see some daylight around the top of the shaft once it's on the biscuit. Well I couldn't get a group at all at 20 yards. One time I'd be shooting to the left, the next time to the right. So I put a RipCord on the bow and my typical groups were back. The bow is shooting great. Here's the question, do you think I needed the large biscuit and my problems wouldn't have happened. I don't have a spare large insert so I can't try it and hate to buy one if I'm wasting my time. Thanks for any feedback.
