I was a a bit surprised when I compared load data between my 49th ed Lyman reloading manual and my 2nd ed Lee Modern Reloading manual for S&W460 load data.

Lyman: Barnes XPB 250 gr., H110 powder
Starting : 36.5gn Max: 38.5gn
1985 fps 2123 fps

Lee: Barnes XPB 250 gr., H110 powder
Starting : 39.0gn Max: 41.5gn
1985 fps 2133 fps

I am a little spooked when I see one starting out above the max recommended load of another source. I would greatly appreciate any help regarding this issue since this is not a round I want to risk an excessive load on. (none for that matter)
Thanks
