This picture attempts to explain part of the problem when shooting a full bore conical from a TC barrel
Do you have any sabots and bullet you could load into your rifle?
And as in your last post - tightening the scope down could also help.
Yes i do have some 250 n 300 gr xtp's i can load up n try. Plus some .429 with gn sabot. I had a learning curve back yrs ago on them
