Anyone use VV3N37 powder for 45 colt

I see Natchez has Vihtavuori 3n37 with free hazmat and it looks like it should fill a 45 colt case well at moderate velocity and I was wondering if anyone here has used it for cowboy loads. I was thinking of getting a 4lb jug. I have used the N320 in subsonic 9mm for silencer use because it has virtually no flash and super clean when loaded down, just thinking the 3n37 might have the same properties

Seems like it would be a little slow burning for cowboy loads.  Should be about like HS-6.  A lot of guys use it for their 9MM open loads (9MM loaded to about 1600fps).  I may get some just because HS-6 is so loud.  Maybe the VV 3n37 would be quieter.

I use it for my 147gr 9mm loads. I still use trail boss for CAS 45 Colt loads. I've got 8+ # of each.
