RED FLAGS would come up with any subsonic .338 Lapua data.

But looking at this data I don't believe it is subsonic - rather the velocities are given in meters per second. The speed of sound at sea level is about 1150 fps or about 354 meters per second.

By great good fortune, I just joined the forum today. In my introduction I mention getting midrange data for the Lapua from the bullet and powder manufacturers themselves and I am willing to pass it along.

Unfortunately they didn't include anything subsonic.

Call Sako and find out what suppressor they recommend and call it good.

Welcome and nice to meet you here

Subsonic in the .338 Lapua is very impractical, even the .308's pushing it for subsonic case capacity. Best to use something the does this job well, like the 7.62x39, or .300 Whisper.
