I found 45.0 Varget to be mild with the 120 NBT in a factory tubed Remmy. Take that as just reference data, of course. I was seeing 2950fps from a 22" tube.


Me personally, I'd go up 0.3gr increments until you just see some pressure starting then back down 0.5gr or so. That or stop when you hit the velocity you want if you don't find pressure first.
