thought it was an older one, think I have the same oldie on the bench
For me, AI is about reducing trimming not speed. IME, on all the AI rounds I've been around if one keeps it to similar and sane pressures one will pick up 100 fps over the standard round. 100 fps for me isn't anything to dick with to loose the smooth feeding of the standard case.
But, that just me and where I am in my loading journey.
I long ago figured out I can make rounds go about any speed I really want them to go
All sans pressure of course.
