I was on the hodgdon site but maybe I game up to quickly. The info it shows for 150 grain is..
150 GR. SIE FN----IMR 4064---.308"---2.550"
Min. 31.0---2106---33,300 CUP
Max. 33.3---2236---36,200 CUP
The 160 grain takes 28.7--30.5
Just to call it safe I think I'll start with 30 grains.
The C.O.L. of the dummy I made is 2.7 which is .2 longer than a round nose but it's all tapered. Either way it will be a single shot to be safe.
