[QUOTE="Tac-O, post: 1816690, member: 109994"] I have been working off of Lee's manual and hodgdon data, which show 62gr max. Just recently, I noticed that Sierra's Max was much lower than the other two. I just started working up around the max to see if it develops pressure signs and how the loads shoot. Even at 63.0gr, which is 1.0 over my max, the only sign is slightly more flattened primers, but nothing close to many pictures I've seen of flattened primers as examples of when to back off. I definitely started at the bottom end of 56gr, and 57.5 is the best I saw, then just under 60, and 63 seems decent so far. [/QUOTE]
