Is your 3050 load accurate? If so, why change, bah bah bah.
Did use 2217 for a while, but then changed to Retumbo(pretty much 2225 from ADI). The max published data for this is 71gr with a 150gr bullet. I start to see some very minor pressure signs at 71.5. I know some guys with 270WSM that can get over 72.5gr without pressure signs and seating the bullet out more if the rifle allows. My rifle has a shorter throat than theirs.
There are report in getting 74gr into a case in the US, and get over 3400fps with this powder.
Start low and work up to suit you rifle.
Good luck and don't blow yourself up!
