I am still working up loads for my 308 with 150 gr ssts, and noticed a few postings for loads with 42 grains of varget. (relatively new to reloading)

Hodgdon lists the "starting" load as 44.

I know they say 4895 can be dropped to as much as 60% of the max load, but how much room from starter loads is there on varget ?

If working DOWN is there the same progressive signs of pressure ? the info i found made it sound like there could be a sudden spike in pressure when the case is too empty..
