in most cases yes
they have never Made a Vmax in .310
i have measured every part of them ,, weighed them , cut them in half they are the same thing
the biggest giveaway is the CANNELURE ,, No VMAX has a CANNELURE only SST and AMAX
Only in the 123gr Zmax SST
all group sizes where similar through the powder range for both SSt and Zmax , best group was both the Zmax 27 Grs and the SSt 27 grains (pictured above) most groups where around the inch ,, biggest being 1.5 inchs
