I shoot the NEF sidekick also. I have had it a couple of years. I always shot Hornady sabots from my previous muzzleloader, so I continued using them with the sidekick. I was so frustratred while trying to sight it in using sabots, I could not group my shots if my life depended on it. So I tried Powerbelts this year with amazing results. My group was so tight at 75 yds the bullet holes were touching. Just curious if you have had the same problem. If so you might try the powerbelts.
