[QUOTE="Mikecr, post: 2734384, member: 1521"] A 260AI is a great example of improvement over a parent design. The 260 is lethargic as under capacity for 140gr bullets. Ackley improvement takes you to perfect capacity for this. You could go up to 6.5x284 or larger cases, but YOU WILL find lower efficiency and lower barrel life with this. Most people end up downloading the 6.5x284 to a point no better than a 260AI, while burning way more powder. The way to see thjs stuff is to build a table, even if mental, of all cartridge design attributes (incl pros/cons) and rank them in comparison. With this, it could be that there are situations where Ackley improvement is not a gain for you (or maybe anyone) (overall). I imagine it would be easy for me to conclude that a 264wm AI makes an already extreme/bad design -even worse. But for any caliber, I'm sure there is a better capacity cartridge for it that can be improved, leading to gains. [/QUOTE]
