I want to load up some surplus FMJ bullets for my 1895 Modelo Chileno 7x57. I see that these two powders are on the same line of my burn rate chart; are they interchangable?
Considering starting out at 40 gns with the 174 gn FMJ.

According to QuickLoad, in that very mild load application these two powders are quite similar, essentially interchangeable (26 to 27k psi, a bit over 2000 fps velocity).
Thanks!
