You can get 3000 fps with the 140's, and into the 2900's with the 158, but with the 180's I would guess that as Savage says the 2800's would be a reach.
When loading 180's in the .358 Win with RL-10 I worked up loads over the chrono with the old 99. A velocity of 2800 seemed ok but more powder drove the bullets even faster. I had no idea what the pressure was? There were no obvious excessive pressure signs.
It just seems that, in theory, 2800 fps is a lot out of the case.
RL-10 is excellent in the .358 and other rounds.
