.224 Valkyrie? Future competitor to the 6.5 Grendel?

[SHORT-N-SASSY]

. . . The number they're showing is 2700fps mv, but we don't know the barrel length. Some say 20", some say 24".

From the 6.8 forum

Here it is straight from a Federal employee-
Justin Johnson 90gr at 2700fps from a 24" barrel. We are getting 2630 to 2650 our of 20" gas guns. #federal employee . . .

Now that it's been confirmed that the stated 2700 fps Muzzle Velocity of the new .224 Valkyrie is from a 24" barrel, and given that Sierra shows the Ballistic Coefficient (BC) of their .224 diameter, 90-grain VLD bullet to be 0.563, I researched the 6mmAR Turbo 40 Improved --- (http://www.6mmar.com/6mmAR_Turbo_40_Improved.php)

Using the respective Muzzle Velocities of the 6mmAR Turbo 40 Improved, with the Berger 108-grain BT bullet and Alliant 2000-MR, from 26" and 18" barrels, I extrapolated for the Sierra 110-grain HPBT Matchking bullet, with a stated BC - 0.617, and dialed-in a Muzzle Velocity of 2750 fps for the 6mmAR Turbo 40 Improved (A) to compare against the .224 Valkyrie (B). NOTE: This comparison is at sea level, with a 10 mph crosswind ---
