Not just that, but burn rates are determined under standard conditions by a powder maker, who then estimates what his competition has. The data isn't openly shared. This is why two different burn rate charts often have things in different order. You can trust Hodgdon or Alliant or Western or Norma or any other powder maker to have the burn rates of their own powders in the right order, but not necessarily those made by other companies.
The other problem is that higher pressure and temperature make a powder burn faster than the standard test conditions do. Unfortunately, how much faster is not consistent among different powders. Some respond twice as much to a pressure change as some others in the same class do. For this reason, while a burn rate chart can suggest candidates to look into for a particular application, that's about as far as it goes. Also, because of the jumps in burn rate that are present in most simple order listing charts, I find the type that displays powders grouped by similar applications are more useful to look at and take a lot of the guesswork away.
An example is here.
Another good type is Western's. Rather than find a specific order and knowing some powders will overlap in some lots, they just have rows of names that are roughly the same. Lapua does the same, as does Pulver, GS Custom, and Powder Swiss, among others.
From a quick look in QuickLOAD, it appears N110 too bulky. The charge weights are about 13% lower, but often are highly compressed loads, nonetheless, as compared to H110.
