Nino,
Do you have a chronograph?
140gn is super heavy for this compact calibre, and marrying it with N135 is way too fast. You can shoot 140 in Grendel, but even with a better suited powder it will be slow and with a rainbow trajectory. The lighter weights work well: 95-123gn.
I have not used VV but 530 and 540 appear to be the optimum powders, both on their website and when looking at equivalents. It's a pity VV does not post pressures with their 24" test barrel.
Very nice looking rifle - what do you plan on shooting?
