I was firing some 9mm loads today, and noticed on these cases, that the firing pin strike looked deeper than it normally is.  On one of the cases, it actually poked a tiny hole in the primer, and some powder residue escaped from that hole.   The load is Zero 147 gr JHP, 3.8 gr of Unique, Remington 1.5 primer, Winchester case and an OAL of 1.140.  This appears to be a starting charge.  After I fired these off, I switched to a different load that had CCI 500 primers, and those all looked normal, so I am guessing that maybe the Remington's are soft.  However, I have fired Remington primers earlier in the summer, a few times, and dont remember seeing this.  There were no indications of high pressure on these loads.  Is there anything to worry about?

Rem 1 1/2 primers are Not to be used in high pressure rounds.  Says so on the box.

Pierced primers are to be avoided.



Check your firing pin for damage.

I just checked, and it does not say this on my box.  Not on the outer box that holds all 1000 primers, or on the individual box that holds 100.  I purchased these primers probably 8 or 9 years ago, and unless something has changed, there is no indication that these primers are unsafe in high pressure rounds.

I checked the firing pin this evening, and sure enough, there is some irregularity on the tip of the firing pin that I can feel with my finger nail.  Its extremely hard to see, but I can feel it.  Im not sure whether this was the cause of the one pierced primer, or if the firing pin was damaged because of the pierced primer, but regardless, I will be replacing it.

That's a good plan.

From Rem Web site.

[i]In pistol cartridges, the 1-1/2 small pistol primer should not be used in the 357 Magnum, 357 SIG or the 40 S&W. The 5-1/2 small pistol primer is the proper selection for these rounds.

In rifle cartridges, the 6-1/2 small rifle primer should not be used in the 17 Remington, 222 Remington, 204 Ruger or the 223 Remington. The 7-1/2 BR is the proper small rifle primer for these rounds.
[/i

I take this to include the 9MM as it runs at the same pressure as the 40 S&W.

Remington prints the warning on the bottom of the carton in not terribly large print.  I wouldn't be surprised to find old cartons without a comment.

I think I will save these primers for a lower pressure round just to be safe.  Do Remington 1.5's have the reputation of being soft?
