Given that supplies of things like primers are unpredicatble (ie the have magnum small pistol one day, and standard the next, ditto for large pistol), I should probably devise loads for each.
One thing I do know is that, prior to this thread, I had not known about the variation in peak pressure based on primers before and some some of my .44 cases may have some CCI, some other Fiocchi.
However, none are magnums...
As for the value of changing to magnum primers for N-110, I doubt that it is helpful, unless perhaps for extremely cold weather.
Well it does get cold here, but on the plus side if I were carrying the .44 in the woods, it would be under my jacket.
