kneelingatlas Posted October 17, 2014 Share Posted October 17, 2014 Has anyone ever tried SP-3 in 38 super? According to my estimates it would take something like 12-13gr of powder to make major with a 115gr bullet, but if it's anything like SP-2 it should easily fit in the case. Seems like a 9mm case full would be awesome for a minor load Anyone? Link to comment Share on other sites More sharing options...
