Try a different sabot.



My Black Diamond is the older model with the shorter barrel and the plastic stock. It is a good gun but mine had a problem. Sighted the gun in with the ramrod in place and it shot very well. With the ramrod removed the bullet went to a different poi. The barrel did not fit well in the stock.

TC floated the barrel by making the rear stock/barrel contact point lower than the front one. That caused the barrel to be jacked up when the rear screw was tightened. The rear contact point in the stock was built up with Acra-Glas jel and no more problem.
