Yep, any minor differences in bullet shape in V-Maxes and Z-Maxes are due to differences in manufacturing lots, not basic design.
Aside from the information from Hornady, I have plenty of both on my shelves, in both .204 and .224. They shoot identically with the same loads, and expand identically on varmints.
You'll also often see minor lot-to-lot differences in Hornady Interlocks, or Sierra GameKings, Nosler Ballistic Tips, or any other popular bullet.
