The following is a target shot early this morning please review and feel free to comment. All loads were in a cheddite hull utilizing hard cards and felt wads where needed (smokeless). Please be aware that I in no way advise the use of 777 at these levels. While casehead expansion was acceptable recoil was nothing short of insane. I'm a young, strong and experienced shooter and I could not control this firearm with this load. 150 grains of Black seemed tame after these. On shot tabs B=Black L=Longshot 4756=IMR4756 777=777. I will post casehead measurements on another post

Much to Daryl's delight(I'm sure) 150 grains shot the best and deserves a proper grouping.
