On paper, 150s and RL26 appear to be less of a viable option than 160s.
You would have to cram 112.4% (~54.2 grains) under a 150 to reach 60kpsi and 2,900fps+.
Just remember this is an estimate, and could be completely bogus.
I run light neck tension, and have trouble keeping bullets seated past 108% case fill.
