I am within striking distance of finishing my Krag 35/40 sporter. Looking at starting loads for 308 W with heavy bullets sometimes they are right at 40K CUP and the same powder in a Krag at 40K CUP (was PSI)  shows the same charges with Varget. My go to powder has been Varget for some time and Hodgdon shows;
46 grains at 42,800 CUP load for the 358W with a 220 bullet
45 Grains at 40700 CUP load for the 358W with a 225 bullet
34 grains at 27800 CUP load for 35Rem with a 220 bullet
38 grains at 33300 CUP load for 35 Rem with a 220 Bullet
Hodgdon does not seem to be worried about detonation with low pressure loads in the 35Rem with Varget.
Lyman's reloading book had very similar data for 30/40 308W and 358W. I will have to borrow my son's Lyman book to verify.
So the question is does 40 grains as a starting load and 45 grains as a maximum load sound reasonable for Varget in a 35/40? One advantage of using loads like this in Varget, there will be no chance of getting an accidental double charge.
