Rule3,
Bingo THIS:
Tom identified the discrepency that you were asking about.
If you look at enough data long enough, these head-scratcher-questions start having answers that are apparent.
The Alliant website was cut-and-pasted from their older load data, generally. Somewhere in the cut-and-pasting, the editor or copier got sloppy (or didn't know the difference, because they're not a handloader/caster) and listed swaged bullet data as "cast" data.
If you go to that same Alliant webpage for the 240gr loads, and hit the back button, and go to the 250gr cast (Keith) loads, you'll see they list up to 11.0grs for the same powder. Now, that's a heavier bullet, with a heavier load - sounds dangerous don't it? Actually, it's not, and the 11.0grs load could be used with the soft swaged bullet safely (as far as pressure goes), but you'll lead the heck out of your barrel.
So, the technicians made those loads different, and I say it's because of what Tom noted. Unfortunately, someone not so smart put the data on the website and confused things. This is what happens when humans are involved - we're just not perfect, much as we try.

I guess you can say that my 629 has been proof tested. The gun held up but the recoil sure was on the heavy side.......................
