[QUOTE="therifleman556, post: 1621563, member: 101898"] Roger that, you should have another 100-150 fps available with different powders. I had Retumbo pretty compressed to get the 3220 fps. I'm not sure I want to stick with that powder though. When I get time I've got loads cooked up with 7977 to try. That powder is close to Magpro in burn rate but is a more stable powder. Magpro has been the go to for people seeking speed in the 270 WSM. Another thought... Are you able to check velocity? If you're coming in under what the data says you should get and have not observed pressure signs yet, you might try going to a higher charge weight. Sometimes groups will shrink when pressure gets up towards maximum. A chronograph is a must for this though. [/QUOTE]
