Have a TC Strike that is driving me crazy. Vertical string at 100 yards is in the 6 to 8 inch range. Windage is fine at about 2.5 inches.

Have tried Blackburn 209 and triple 7. Bullets have been Hornady SST 250, Powerbelt 245 hp, Powerbelt 300, Hornady 240 handgun bullets in green sabots, 300 gr Sierra in green sabots. Charges have been 80 to 100 grains by volume. All have the same issue.

Bases and rings are fine. Have had 3 scopes on it. One is a proven reliable optic. I have no issue shooting decent groups with any other rifle including my friends MZ.

Speaking of said friend he can buy a muzzleloader in a bubble wrap package and shoot anything out of it and get 3 inch or less groups at 100 yards.

Talking with TC has been useless. They state I have not found the right combination yet.
