Best Post: AI Fool
If you really want to understand Ackley Improved get the PO Ackley manual Vol 1 and read his articles about three times. I doubt anyone here has done that. Everyone is only concerned about velocity.
The most important thing about AI is the *way* it handles pressure. Every cartridge with heavy shoulder slope is like a torpedo against the boltface. The weakest part of the lockup. AI puts no pressure on the boltface. At ~63,000 psi the primer will fall out. You *probably* can not hurt your self. At the same time and for the same reasons recoil will be reduced.
With that in mind, everything AI works...
