Might be the BH... 95 grains of BH really does not do a lot with a 200 grain bullet. By the time the BH is ready to really burn well the bullet is out the barrel...

I am thinking you might have been getting the bullet out of the barrel @ about 1900 fps.

Sometime try your GOEX... 110/120 grains and see if that might help..

I have shoot them with the Harvester Blue 4050 sabot but the MMP Blue 4050 is a thicker sabot, and even though it is thicker it compresses down really well in even a tight bore really makes a good seal.
