Default Remington 1 1/2 vs. 5 1/2 Small Pistol Primers

Folks,

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!

Mike

Looks like you answered your own question. (Thinner cup)

Here's a primer cross reference. Primer cross reference chart

That cross reference indicates the 5 1/2 is a small pistol magnum primer. I wouldn't use either one in a .357 Mag, but I would use a 6 1/2.

Default ... knew I shoulda looked ...

Thanks, gents!

Tho I've used handloads.com for lots of other stuff, it completely skipped my mind when this question came up.

Remington's packaging is a bit of a mystery. If they would just label 5 1/2s as small pistol magnums it would save us from reading the microscopic print!

Anyhow, I use CCI 400s in my magnum loads, thanks to an earlier tip from Paul.

Thanks again!

Best,

Mike

Mike,

It would seem that the addition of the "M", like in the 9 1/2 M, would solve a lot of confusion.

rem 1&1/2 vs rem 5&1/2, being disatisfied with all forum answers about a year ago, i call rem factory, and got this answer. NO change in
power, just cup thickness. they use 5&1/2 for factory loaded 357 sig and 40 S&W to prevent flow-back into the firing pin opening. i use it for everything including 38spl & 380 with no problems. they said it is NOT a magnum primer.

Default ... hmmm ...

jwh32,

Now, that is interesting!

Confirms my use of CCI 400s for magnum loads. (I generally stick with 2400; old fashioned, I guess.)

Paul5388: Would a change in the handloads.com primer comparison chart be in order? Just asking.

Best,

Mike

Mike,

A change to the chart would be beyond my job description. I can edit posts and do general moderator functions, but I don't have the ability to change any of the articles and etc.
