Greetings!
My first post here. I hope I'm not breaching protocol. But this caught my attention.
I'm having difficulty, like everyone, in locating Standard Small Pistil Primers. I have Magnum SSP in my reloading locker.
I contacted CCI and a few other Primer manufactures for info about substituting Magnum for Standard Pistol primers.
As litigious as our society has become, they obviously warn to not substitute Magnum for Standard. But, the truly useful warning, and it makes sense to me, and I'm sure most of you know this, the primary caution is regarding exceeding pressure limits in already high pressure rounds, like 9mm and 40 S&W.
And to pay particular attention to OAL, since the OAL has such a profound bearing on the initial pressures.
Magnum primers do cause a higher initial pressure spike than standard... so work up from midrange loadings or less for safety's sake.
I have used magnum SSP in .38 spl mid-range loading before, with no visible signs of overpressure.
I primarily carry, shoot, and reload 9mm. It's my chosen SD round. Historically, it was less expensive to shoot than 45acp and generates less pressure and wear than 40 S&W.
I'm working up some loads for my 9mm using the Mag SSP, so we'll see how it goes.
Anyway, the jest of my post was to use caution in working up higher pressure generating rounds and beware the OAL.
Great Site, btw!
