[QUOTE="samson, post: 87449, member: 1226"] I have been working up a load with this powder and have found that under a 190 SMK the books post a max load anywhere from 68.3 to 72.8 grn. Why the difference? I am shooting a 28" hart barrel with a mod 70 action in a 300WM. I am getting the best groups with 72 grns @ about 3025 fps. I am wondering if I am too high? I havent seen any pressure signs yet. [img]/ubbthreads/images/graemlins/confused.gif[/img] [/QUOTE]
