Hello all. As many of you have, I have hard nut to crack on getting my tikka .308 22" barrel to tighten up into a respectable group. Have tried all the traditional powders. Varget, Re15, BLC-2, and CFE 223. Used 165 Nosler Accubonds and Beger 168 classic hunters. Have done powder charge workups and bullet seating tests, starting from lands to 120 thousands off. The ONLY thing that has showed promise was 45.5 grains on CFE223 at 10 thousands off the lands. Tried seating it deeper incrementally and groups opened up. All I read is that the 308 shoots "lights out" with Varget and Re15. Not mine!! Any thoughts?? Thx in advance. Pete
