Varget really isn't too usefull for what you want.
130 grain, maybe up to 135 grain is about the heaviest I would go using Varget.
So, you have three choices:
1) Use a 130 grain bullet;
Varget From 49.8 grains to 54.4 grains
Winchester LRM Primer
2) Us a different powder;
RL-22 From 60.0 grains to 66.0 grains
Winchester LRM Primer
3) Go ahead and use the Varget and the 140 and take your chances...
