.224 Valkyrie? Future competitor to the 6.5 Grendel?

I also noticed his BC for the 90 gr VLD was significantly higher than Berger's own posted G7 of 0.274, so I ran with the corrected BC.

Next, I chose a tried and true 123 Scenar for the Grendel. It is a solid choice for VLD comparisons.

Lastly, I updated the 77 grain from the SMK to Berger's Tactical/OTM, with an improved .192 G7 BC. Because the Wylde was simply the same projectile running 50 fps slower than the 22 Nosler, I omitted it entirely as being redundant.

I kept all the velocities as previously posted, and ran the numbers using the Applied Ballistics engine with standard atmospheric and temperature values. With the playing field now evened, the results are somewhat different.

Even still, the Valkyrie does maintain a slight edge on drop and windage, but never gets close for retained energy at any distance.

Thank you for your work, intuitively, your numbers seem more realistic.
