30-40 subsonic

[Paul in Oregon]

I have been shooting my old Krag at 50 yards with the Lee 100 grain plain base pistol bullet and 3 grains of Bullseye. Accuracy is good , US quarter sized 5 shot groups. I have Unique, 4227 ,2400 and Trailboss . Anyone have any idea what grains of each will keep me subsonic. I can`t complain about the Bullseye but I would like to experiment with other powders. Thank you,Paul.

trail boss should work.
maybe 10grs of the 4227 would work, I know that is subsonic in the 300 black out with a jacketed bullet.

According to Quickload:
In a 24" barrel 3grns Bullseye will give you 876fps, 4grns Unique 974fps, 11grns IMR4227 949fps, 8grns 2400 939fps, and 4.5grns Trailboss 976fps.
