No, I use Unique at slightly higer velocities than CAS standard loads. Others who are methodical loaders I trust say that it is doing what the advertisments and releases say.
I use Unique too for my indoor shooting. I cut mine back to 4.5 Grn in 44 Colt case pushing this 44 Rem 248 Grn outside lubed bullet. .451 Dia drive bands (3),2 lube grooves, and .429 dia.heel w/crimp groove, RFN.
Any more than that and I had a lot of unburnt powder.
I'm trying to find some Trail Boss to try.
I saw some of this at Gander Mountain yesterday and almost picked up a can. I use Pyrodex P and have no complaints. I guess I'll just stick with Pyrodex for now.
The only thing I can say I don't really like about the Pyrodex is that it seems much more susceptible to moister than my old Goex BP. That's not a good thing here in the eastern mountains. High hummidity in the summer, lot's of rain in the spring and very cold and damp in the winter.
I have had several loads not go off due to slight grease/ powder contamination that never happened with the old BP.
The Pyrodex powder seem's to give consisten results shot for shot.
