The N150 isn´t my powder and like you said the N160 is more for the .300wiinmag and such bullets. The barrel is getting hot to soon. I use the N140 and worked out carefully with speed testing and i ended up with 43.2grs which is at the upper end for the.308 Win but more at the lower to to the middle for a .30-06 with the 185grs bullet. With the 167grs bullet it was around 44grs to 45grs and gave good results. The IMR 4064 has a very similar burning rate like the N140. Here´s the burning rate chart from VV.

The N140 ended with the 180 grs Lapua Naturalis bullet and if you compare it to the Scenar bullet you will see that the Naturalis for its shape will have more rsistance and higher gas-pressure than the Scenar with its shorter guided surface. So if you´ll stay at max 46 grains with the Scenar ( 48.3grs for the Naturalis) ,which aren´t neccessary, it will be a safe round. And i use it since years. But you know that any rifle is different to a other one, i would say it is safe for my M17 but i don´t know if it is for yours.
