I'd like to grab powder for my new 9mm MP 147gr HP mold but I'm also shopping for a 220gr 300 Blackout mold and since I need to buy new powders for both, I'm curious if there are any powders that will work for both?
Right now, of the powders I can use for my 9mm, my dealer can get me:
700X
Titegroup
W231
But I also have a bunch of other powders. Those three are just what are available to buy that'd work for 9mm.
Any thoughts on the 9mm and 300 Blackout sharing powders?
...or is it just easier to buy 2 different powders?
EDIT: I'm looking for both rounds to be subsonic.
Thanks!
