VihtaVuori N3SL Powder

As I noted in a different thread, I recently bought a fairly large lot of reloading components. Among the items, I got about 35+ pounds of VihtaVuori N3SL Powder. I did a web search and see that it is listed as a shotgun powder, but I can't seem to find it on any powder burn rate chart. Does anyone have any knowlege or load data for the use of this powder in handguns ? Any info would be appreciated.

Under the trees at the turn of the road,
And only pausing to fire and load.

Thank you for the info. I just ordered a VihtaVuori loading manual, so that should be a help. Anyone else have any ideas about using this powder in handgun cartridges. I have a lot of it, and it would be really nice to be able to use it in my faviorite cartridges.
How about a discussion of working up loads without the benefit of published loading data ?

Here is the reply I got back from VV in case anyone else is interested.

3NSL is flake-type smokeless propellant that can be used for pistol and
revolver cartridges and shotshells. We have developed 3NSL data mainly for
Cowboy Action Shooting with lead bullets:


.38 Special

158 grs lead COL = 1.437 inches

3NSL starting charge 2.8 grs maximum charge 3.3 grs


.44 Special

240 grs lead COL = 1.539 inches

3NSL starting charge 4.4 grs maximum charge 5.3 grs

267 grs lead COL = 1.539 inches

3NSL starting charge 3.6 grs maximum charge 4.7 grs


.45 Colt

200 grs lead COL = 1.594 inches

3NSL starting charge 6.3 grs maximum charge 7.3 grs

250 grs lead COL = 1.594 inches

3NSL starting charge 5.1 grs maximum charge 6.1 grs


Use maximum charges with caution and have good shooting!

Best regards,
