I searched under "small pistol primers" to see if this issue had previously been discussed, but I could not find it. If I'm repeating the issue, I apologize.
During the primer shortage, I bought 1000 Remington 1-1/2 small pistol primers which were new to me because I used 5-1/2's in the past. A warning is on the package that the 1-1/2 primers should not be used in .357, .357 Sig or .40 S&W as high pressure may pierce the primer and create a danger to the shooter.
That implies they are o.k. to use in .380 Auto, .38 special and 9mm. But I reviewed Lyman's 50th edition in the calibers and bullets that I use and listed the maximum CUP pressure associated with one of the several powders listed.
.380 Auto 90gr HC 16,300 CUP
.380 Auto 95gr FMJ 16,400 CUP
.38 Special 125gr JHP 16,700 and 18,300 (+p)
.357 Rem Mag 125gr JHP 44,100 CUP
9mm Luger 115gr JHP 32,500 CUP
It strikes me that the 9mm generates a pressure more associated with the .357 Mag than it does with the .38 Special and .380 Auto. I wonder why it is not also not recommended for use with the Remington 1-1/2 SPP.
Is anyone aware of any similar caution that might exist but has not been made public about using the Winchester small pistol primers?
