I just scored a pound of VihtaVuori 3N37 powder and have a question.
Back in the day, we used magnum primers for slower powders like, Alliant 2400. The hotter primer was to guarantee ignition of all the slower powder before the bullet exited the barrel. Anytime we used 2400, we used magnum primers.
But, for faster powders like Alliant Unique, we used standard primers. Anytime we used Unique, we always used standard primers.
But for the above powder, VihtaVuori 3N37, in some cartridges (357 magnum, for example) they recommend using magnum primers.
In other cartridges, (44 magnum, 45 ACP, and 9mm, for example), they recommend using standard primers.
My question is, if a powder requires a magnum primer, should it not require a magnum primer in all applications? And if a powder can get away with using a standard primer, can it not get away with using a standard primer in all applications?
Or is VihtaVuori just a weird powder?
