I thought the AI loading procedure was like this: Start at the standard cartridge max to fireform. After that, keep adding powder until primers start blowing. Then back off a tenth grain, or maybe two tenths, for a safety cushion.

Then if the desired velocity is not yet reached, the second method is to switch to a faster burning powder in order to shove more of it into the case. Proceed once again until primers blow and back off a tenth or two.

I don't shoot any schit rifles,so don't have to pull spark plugs on ammo. For me,the Improved chamberings don't get a pressure boost and are treated as SAAMI stuff,in that regard. Often the impetus for me to Improve,is to yield a true shoulder from which to afford finite headspace control. Other times,it's simply to maximize the capacity of a schit initial design(Hornet,22-250,300 H&H,375 H&H,etc). Hint.
The 223 AI is a rather nice case design,which in turn does rather nice things,so I've a goodly herd and it's my favorite chambering of All Time,due all that water under the bridge. Hint................
