The older IMR guide from 1997 showed:
150 Rem Pointed Core Lokt
46.0 grains IMR 4350 (compressed)
2415 fps
36600 CUP
As you can see, velocity is rather low as is the pressure using IMR4350, and I guess Hodgdon dropped it for this reason. Obviously it is very safe, and if you like what you see and it meets your need for a 30/30 spec load, try it. Any hope to even come close to full potential loads with IMR 4350 in 308 is not going to happen, but at least it will allow you to use what you have.
Good luck!
