[QUOTE="mciver, post: 311003, member: 11943"] J E has a great point...accuracy should always be the goal...not speed. Having said that, as I stated earlier, I had bad results with rutumbo. I originally loaded it in my custom 30-378(very similar in velocity to your RUM). I used 113gr...as it stated on the can and all I can say is...Holy ****!. first three 180gr scirrocos were coming out at nearly 3800 fps and I could barely get the bolt open. I got the pics of the chrony cuz everyone standing around almost **** themselves. I immediatly pulled the remaining bullets and re-weighed the powder and it was right on at 113gr. Grabbed new brass and primers..same thing. Went to RL25...108gr with 200gr accubonds and averaged 3325 with them...no excessive pressure, no primer issues and brass was spot on after the shot. Just my experience. RL25, 22, H1000 and 7828 are my main choices now. $25 bucks for a can a powder isn't too bad to see if it works better than what you already have.
