Yeah 2900 won't happen if pressures are held to a sane level with a 22" barrel. Hornady is at 2800 with a 25" barrel and 77.6 of H1K.
But, if there's one thing I've learned over the years that would be we can pretty much talk ourselves into whatever speed we want to justify if it means enough to us.
Too bad we don't have good pressure testings systems at our disposal. I really think they aren't far off from being available to us then all this pressure guess and by golly would be eliminated.
Regarding pressure, as one of my wise friends says "pressure equals speed and speed equals pressure"......
Going back a long time and I dislike using memory but back then I ran a 23" 300 Wby and if I recall right with 200's I was a bit over 2800 with H1k.
