You didn't say what kind of Swede, but in military barrels and chambers, the 129 Hornady flat base or SST is as good as any and better than most. Almost any powder can be more than satisfactory. The Swede in my experience, is not picky. If I could only have one powder...probably something near the burning rate of H4831...but when I was shooting competition out to 600 yds with the Swede, 4895 was the berries with SMK 140's.
