I had set my knight Mk 85 thumbhole 3'' high at 100 Never had a chance to shoot past that because of lack of time, till now. I had one round left in the chamber from Hunting season and wanted to see how it would be at 150 yrds. I put up a big cardboard box and aimed for the little green te leaf on it that was in the center. It shot abot 1.5'' to right and dead center for up and down. My groups at 100 were right about 3/4''. I used 250 barnes tipped Tmz with 100 grains of tripple7 ( 2 pellets.) I just have to put a deer in front of it..lol!
