Those "max loads" for Alliant powders must be from their latest catalog where they use soft Speer swaged bullets and dialed everything back to prevent leading. With cast bullets, you can drive them much faster, and I'm looking at Alliant published data right now from a couple of years ago before they neutered it. For 240 grain lead gas checked bullets with an OAL of 1.6" (the data would be the same without the GC but you *might* get leading):

Code:

Bullseye         9.8gn  1175fps  34.4kpsi
Red Dot          8.8gn  1175fps  34.9kpsi
American Select  9.2gn  1180fps  33.8kpsi
Green Dot        9.5gn  1170fps  34.8kpsi
Unique          11.8gn  1255fps  35.0kpsi
Power Pistol    
Herco           12.5gn  1330fps  33.8kpsi
Blue Dot        16.6gn  1475fps  34.7kpsi
2400            20.6gn  1510fps  34.7kpsi

In my opinion, Herco is the sweet spot between price and performance with cast bullets.
