Hodgdon has been buying there ball powders from Winchester and when Hodgdon bought them out they decided instead of marketing two of the SAME powders that they would drop the H414 and stay with the 760 designation to prevent redundancy. The W 760 and the H 414 are the same powder so the load data is the same.
The only difference I have found in ether powders, has been in the different batches (Common to all powders)

Are all USA ball powders made by St Marks/General Dynamics in Florida? Would that include Alliant Power Pro Powders like Varmint, 1200R, 2000MR, & 4000MR? Don't know about 2000MR but 4000MR, a ball powder, appears to have been subjected to some extrusion process. Other ball powders appear to be rolled flatter to some degree, possible to inject some type of deterrent into each tiny grain.
It appears that Hodgdon i
s marketing two identical powders, H414 & W760, two different labels, two sets of identical on-line Hodgdon data, including data the 2021 Hodgdon annual manual. For years I had no problems with this as the shooters/hand loaders thought W760 was inferior to H414 and left the W760 powder available for me to buy when H414 supplies were gone.
Possibly, there are OSHA requirements that block domestic production of extruded powders in the USA. All the extruded or stick powders that I have seen are made in Australia, Finland, Sweden, Canada, Switzerland & other countries. I have read about horrific powder accidents in the USA where tons of extruded single base smokeless powers have exploded instead of combusting upon being subjected to heat and other nearby explosions during some drying process; this happened during during WWI production.
I have read that excess stocks or aged extruded powder can be salvaged to make ball powders.
Imagine how much shooting could be done with a ton of powder.
