[QUOTE="mrultramag, post: 215081, member: 4467"] Seems like your a little on the light side with the RL25 but I know that powder does differ from lot to lot in my experience. Hornady and Hodgdon both have data for the 7 rum as does Accurate Powder and if you call or email Ramshot powders does too. 3400 fps should be very acheivable with 140's provided you have a 26" bbl or longer. I would look at Retumbo in the Hodgdon data. I will say that the hornady data usually acheives the velocity they say it will. I load a little warmer than book sometimes so I'm not comfy telling you how high you should go as each gun is different unto itself. Suffice to say that in my gun 3500 plus is achievable with 140 accubonds and 3400 plus with 150 partitions. I have found that retumbo powder has given me better accuracy with rem 9.5m primers and RL 25 with fed 215's. [/QUOTE]
