You would hit the "Optimum Bullet Time in Barrel" node 5 quiet nicely (if you are a believer). 1.228 ms puts you somewhere just over 3000 fps.
You couldn't quite make node 4 (1.1016 ms)

http://www.the-long-family.com/optimal barrel time.htm
This is a summary, but links to the original analysis. There is an .xls calculator, or just a pdf table for barrel lengths and barrel times.
QuickLoad provides this "bullet time in barrel" its the last column to the right.
I'm in no way a guru, but it's an interesting study.

What bullet are you saying would hit the 3000fps mark?
I like the 150 ablr bullets (if I can get them to shoot) But I have heard they don't penetrate game. I don't see how not being a bonded bullet but who knows. So I might work up some with the regular accubonds also is why im asking for ql info on them. Ill go with whichever gives me the best groups first.

Sorry, I was looking at the 160. But both the 140 and 160 seem to hit the same note around 3000fps

I can't imagine anyone who is the least bit knowledgeable about terminal velocity of these bullets could make such a statement. Excellent bullet that performs very well.
