Viking357, at times you will find reloading information that are inconsistent as there are variables to laboratory testing. For this reason, you will often see advise to check many different manuals and published sources.
Most powder burn rate charts are not "absolute" rather they group or cluster powders by "relative" burn rates (And even Hodgdon's chart is titled "Relative Burn Rates"). If there are several same or similar burn rate powders, the order listed on burn rate charts may not "absolutely" indicate significantly faster/slower burn rate rather they are in the same/similar burn rate range.
On the Hodgdon "relative" burn rate chart, HP-38 is listed as #28 and W231 is listed as #29. Well, they are same "exact" powder but just because Hodgdon used alphabetical order and listed HP-38 first does not mean HP-38 is faster burning than W231.
Same goes for #65 Hodgdon 110 and #66 Winchester 296 which are same exact powder.

Over the years for choosing powders based on burn rate, I have used "groupings" of similar burn rate powders instead of "absolute burn rate". So for lighter powder charge target loads, I would suggest powders from "faster" burning group of powders and for full power/higher velocity loads, I would suggest from "slower" burning group of powders -
