6.5 Grendel Armor Piercing ammunition data/info...

[JASmith]

It looks as if (on Midway) MV of the Wolf 120gr MPT is from a 24" barrel.

AA shows the 120gr Nosler as 2355 fps @ 50 yards:

That correlates to 2450 fps MV from a 16" barrel, as shown on the AA ballistics sheet you cited. MV from a 24" tube is listed as 2600 fps, which is comparable to the Wolf MPT @ 2610 fps.

...and the 2376 ft/sec in Midway is precisely the same as the listed velocity for the 14.5" barrel and no, I did not or could not find a mention of range for velocity measurement.

This all supports Tony's expression of concern.

I have the feeling that Bill Alexander and his marketing staff are unusually reticent to even approach overselling the Grendel. I think I can surmise a pragmatic motivation, but think the Grendel would be better marketed if the industry standard 24" barrel velocity computed at the muzzle were used in publications. There's ample opportunity to point out the effects of changed barrel length. I can't think of a good reason for reporting the 50 yard velocity.

Yes, folks will be disappointed when they discover that the 16" barrel velocity is a couple hundred ft/sec less. But publishing non-standard conditions for the velocity opens them up to a lot of confusion and the inevitable criticism that follows.
