Both are manufactured by Primex Corporation at St. Marks Powder plant in St. Marks, Fl.
However, just like with Hodgdon H110 / Win 296:
HS-7 / Win 571:
Hodgdon HP-38 / Win 231:
They will be from different lots and may have different burning characteristics.
Use caution and work up after every new lot of powder recieved if using at or near max loads.
Example, my first lot of Alliant RL-22 was somewhat slower than latest lot. The first one would take 61.0gr in my .30/06 with no pressure signs, and >1" @ 100yds with Speer 180 Soft Pt. Velocity was 2,775 fps
Latest max is 60.0gr. and velocity is higher than first batch, and accruacy is off slightly. Velocities are over 2,800fps from 24" barrel. All other components were from same lots as previous loads.
