Using the identical weighed charge and bullet, test it also using WIN209 primers, then a magnum primer but, use different bullet seating pressures. Seat a series of each using 90# seating force, then seat another set using 35# force. What would be the differences in velocity and POI?.....
No, never. Never do i weigh charges. Nor do i know what the seating force of any of my loadings is. There are a lot of things i don't know.
What i do know is this... if i pull the trigger on the buck of a lifetime and it happens to be -15 degrees, the W209 primer in my rifle will instantaneously ignite the Blackhorn powder in the barrel. This i know because i have shot several different rifles, several different times, on several different below zero mornings, several different years, using several different well designed breech plugs, always using W209 primers, or STS primers, and never never never experienced the very very slightest hang fire, let alone a misfire.
The only issues i have ever experienced whilst shooting Blackhorn powder occurred when using OEM CVA hex head breech plugs, plus i did notice a couple so very very slight hang fires in bitter cold weather, one winter with a Triumph.
There will be no more study done by me of shotgun primers, because i am satisfied with my data, and conclusions.
These days i am learning all i can about the Federal 215 large rifle magnum primer. It seems the one breech plug i am using in several rifles, will never wear out. The flash hole doesn't grow. The soot in the flame channel is soft. Thus far i can find no drawbacks. Now.. what i could worry about, is what to do with the 6000 or so W209 primers out in the shop.
