Staball Match vs Staball 6.5 ?

I'm running Staball 6.5 behind 151 gr. Ultimate hammers in my .300 win mag getting around 3200 fps and holding under MOA if I don't flinch, close my eyes, or scream like a little girl when pulling the trigger Just kidding. I'm pretty happy with it. I've got enough Staball 6.5 to run another 200 rounds and can't find any more 6.5 SB powder and figured I would ask if anyone has run Staball Match in a similar or same cartridge-type combination.
I hope if I wait long enough some 6.5 SB will show up but I wouldn't mind working up with a different burn rate of "temp insensitive" powder.
What are your thoughts?

Where are you located? I've got an extra pound StaBall 6.5 I can let you take off my hands.

4-5 hours up north

Staball 6.5 is in the same burn rate range as H4530 it its temp stability is outstanding, around .29fps. SB Match is in the Varget burn rate, probably too fast for the winni.
