I actually was able to buy some primers today. (I was able to buy only 400.) Available were Remington 1 1/2 and 5 1/2 small pistol primers.
I've only used Winchester, CCI, and Federal primers. I gather from other forums that 1 1/2s are small pistol and 5 1/2s are small pistol magnum.
The 1 1/2s have the warning: "Do not use 1 1/2 small pistol primers in high intensity pistol cartridges such as .357 Magnum . . . ." I thought this odd, because I've used other small pistol primers in all sorts of .357 Magnum loads without a hitch.
Not being familiar with the Remingtons (and not ever having seen them on the shelves before) I thought I'd make a general inquiry about their use.
Do the 1 1/2s have thinner cups making them unsafe in Magnum loads? Et cetera???
Inquiring minds want to know.
(BTW, I plan on using them only in .38 Special loads, so the question may be academic, but I (and others) might like to be enlightened!)
Thanks in advance!
