[QUOTE="MontanaRifleman, post: 755656, member: 11717"] Interesting, It's been a little while since I loaded for the 7 RM, but 3000 out of a 24" tube was tops for a 160 bullet using IMR 4831 which was my powder of choice back then. Little doubt that Retumbo or RL17 could push those velocities some. I would be impressed to see 2850 from a 7 RM pushing a 195 gr pill. For the RUM, Retumbo gets me to 3150 pushing the 210 before I start seeing signs of acceptable pressure, no sticky bolt or flowing primers. I back off a half gr for a 3130 working load. Yup, back in the day, the 210 or the 240 SMK were the tickets, They've come up with some good bullets in the last couple of years. [/QUOTE]
