Most semi-autos will live a lot longer if you'll select a powder with a steeper pressure curve. That usually means a slightly faster powder - and stay away from MAX loads, too.
I'd pick a powder in the medium range for this job: 4895, 4064, 4320, Varget, RL-15. In ball types, AA2520, H335, H380, W760.
If it were me, I'd reach for the RL-15, as usual. Load halfway between the Start and Max loads (or 5% less than Max) and I bet you'll be happy.
