If you look at the differences in loads of H110 and 296 in some manuals, you realize that even though they are the same powder, there has been some variation in the lots over time. The maximum loads listed have mist likely changed periodically for the same reason. So, I would suggest that when you work up a successful load with it, you note the average velocity from your gun, and check new lot loads against that standard under the same conditions and adjust to a matching velocity if you find your new lot is too frisky.
