The .308 maxium chamber pressure is 62 K PSI around 60 K CUP, but operating pressure for the 150 gr loads is around 48,000 CUP - 51,000 PSI.
I would not want to use the long range match ammo or extra heavy big game loads in a Model 99 but standard velocity 150 gr Deer loads should not be a problem.
