The Ackley approach might be intersting but I wonder if the gains will be worthwhile vs cost, silly concept, in performance. A rule of thumb is that for every 4% increase in case volume you realize about a 1% increase in velocity. Not hard and fast just a guesstamete. You are gainging right on 8% in volume so by that rule you are looking at 60-70 FPS.

You might post up in the reloading area. If most guys are like me they don't look here much even though I own four of them.
