I was looking around on the net and came across some interesting load data, that substituted SPM primers in loads that normally called for a SP standard primers in published load data.
The loads i saw, using the SPM primers, used a reduced powder charge from 10%-16%, to produce the same velocity as the SP standard primers.
I am curious, because i have a couple thousand CCI small pistol magnum primers, and nothing to load, using them. I use 2 types of powder for loading 9mm, W231 and unique.
Years ago during the reloading component shortage, i worked up a load for my 270 win rifle, using magnum rifle primers, with excellent results. I was wondering, if i could do the same thing for a 9mm pistol round.
Has anyone here used SP magnum primers, in place of, SP standard primers, and if so, what were your results?
Thank's
