The velocities are the maximum listed from the Nosler and Berger manuals, though that gives the 180 an edge since Berger's barrel is 26" and Nosler's 24".
I'd say that 3077fps for a 160 PT is approaching the upper pressure limit, as where 2821fps with the 180 VLD, especially considering the minimal bearing surface of the VLD, is further from the red line. We need to compare the bullets loaded to like pressures. I'm thinking 160 PT versus 168 JLK would be a good illustration.
Addenum- there's not a mountain of difference between the 2 bullets, but small advantages are still advantages, whether in penetration or wind drift.
