Since I started this thread and others, I've done some more research based on recommendations and the TCUs may be just what I want, Now I can,t decide which one! I already have a 6.5x55 and a .280, But I sold my .243 so no 6mm or .25cal. The 7 has the best bullet choices but i like the idea of a 25, Don't ya just hate life altering decisions like this? Makes my head hurt.
