[QUOTE="therifleman556, post: 1613546, member: 101898"] Retumbo is almost a touch too slow even with 150 grain bullets. I ran out of case and didn't see pressure with the 145 ELD-X. Seating the bullets .010" off of the lands, 71.5gr in a Winchester case is heavily compressed and ran right at 3200 in my 24" barrel. I plan on reaming the throat ~.080" deeper and run it as a long action to squeeze a little more in there. The 150 Berger (in my rifle) is almost a perfect fit, touching the lands it fits in the magazine and doesn't hang onto the case like the Hornady does. Magpro has long been the go to powder for speed in the 270 wsm but some say it's finicky with temp swings. I plan to try 7977 which is close in burn rate but supposedly temp stable, and 7828 which is close to your H1000. [/QUOTE]
