N110 is very similar in burn rate and handbook loading weights to H110, and Speer #12 published very good velocities using N110 in the .357 Mag, so I bought a pound. This was at least 20 years ago. It was more expensive than "better known" powders like Hodgdon, Hercules/Alliant but I was pretty ignorant and thought velocity was king.
It performed very well. The thing that struck me was that even at less-than-book-max loads, it burned so clean it was as if I was taking newly tumbled cases out of the cylinder. "Someone" told me that was because of the composition but I failed to quiz him on exactly what that meant.
Recently there was a thread on another forum claiming that VihtaVuori is fixin' to get into the primer business. If so, I would not hesitate to buy their primers, and I certainly would use their powder if I had too much trouble getting the powders I normally use. Note I used in in .357 mag, revolvers and Marlin carbine, and it was great - but never used any of their actual rifle powder in a rifle.
So there - one old, stale data point to use in your evaluation.
