Note: the powder is REACH compliant according to this source so we should expect to see it in the UK at some point(click).

Here's a list of suitable calibres listed for this powder, directly form Winchester's website:Right on the heels of Berger’s newest 6.5mm and .224" bullet offerings, Hodgdon announced this week the release of StaBALL 6.5, a new temperature-stable ball powder from Winchester Smokeless Propellants that should make an excellent accompaniment to Berger’s new bullets.
Hodgdon identifies StaBALL 6.5’s salient feature in claiming it “…the world’s first temperature-insensitive BALL Powder, stable in extreme-hot or -cold conditions.” Additionally, StaBALL 6.5 has the other benefits of a ball-type powder that handloaders have come to appreciate: easy metering through a powder measure for precisely-thrown charges and excellent load density for its burn rate in appropriately-sized cartridges.
