[QUOTE="MMERSS, post: 856534, member: 63748"] Kirby, Here is my data. 300 SMK average MV for 40deg powder temp 94gr Retumbo 2780 fps. 15 thous jump. OAL 3.720. If I shoot 90deg powder temp I start to see slight extractor marks every fourth to fifth round and MV increased 20. If I shoot 94.5gr at 40deg powder temp I see the same signs. I believe I'm right at max pressure with 94gr and the 300 SMK. RL-33, 15 thou jump, 300 SMK. 96gr-2723 fps 97gr-2729 fps 98gr-2747 fps 99gr-2782 fps Current tables say max charge for 300 SMK with RL-33 97.5gr. water capacity 114 gr. Thoughts? [/QUOTE]
