OK, someone with knowledge of these funny European things please clue me in.
I don't really need more primers on the shelf, but last time Cabellas had the great sale a few months ago, I went to check out details on the S&B primers after seeing so many good reports about them. What I found just irritated me and made me decide I didn't want to bother with them. But curiosity has gotten the better of me and I just gotta ask for an explanation. Like most handloaders, I am used to the "normal" primer options: SP, SPM, LP, LPM, etc. And I am aware that some manufacturers have occasionally done away with some of the options by simply making just one primer in a specific size, such as the current Winchester LP primers that are rated for both normal and magnum loads.
But S&B has ADDED one that I have not seen before, aimed specifically at the .40 S&W and .357 Sig.
Their 4,4 SP Boxer/0.40 seems to be the normal SP primer
and the 4,4 SPM Boxer/0.50 seems to be the normal SPM,
But why do they also have a 4,4 SPMP Boxer/0.45 for the two specific cartridges? Their web site does not explain it, and the only distinction seems to be the "0.45" following the Boxer type.
Anybody know what that number is? Is it a brisance indicator that says this primer is half way between the standard and magnum primers? Or is it an indication of the cup hardness?
Whatever it is, the more intriguing question to me is "Why would this specific company bother to make a special primer just for these two rounds when nobody else seems to?" It would seem to just drive up their costs to produce something special that is not really needed and will not sell in significant numbers.
