Danno - Oh I have Pet Loads, 3 Lyman books, 2 Hornady books, Lee, 2 Speer, etc etc, and they all list many Alliant loads. I sure find the Hodgdon books handy with their very extensive loads for all of their, and IMR powders for many many cartridges. I guess the difference is that Alliant lists loads for a particular powder while Hodgdon lists the cartridge then all the loads for all their suitable powders - Hodgdon's approach is much handier IMO and I think it encourages a person to try other Hodgdon powders.
