After 12 years of reloading, I finally had a squib. Not just *A* squib, but THREE in 12 rounds. All three did exactly the same thing. No noise (at least none that I could hear with my ear protection on) and the bullet traveled just far enough to tie the gun up (S&W 686+) Used a punch to tap bullet back into the brass enough to open cylinder and removed. After the third time this happened inside of 12 rounds I packed up my gear and headed home. Pulled the bullets and found they all were full of unignited powder. All had a very reasonable crimp for a plated bullet . All primers had nice solid hits. I had used the same 12.5gr 2400 with a 158gr Berry's and primers from the same sleeve a week or two earlier in my 627 and all fired without incident and grouped well. Did a quick google search and saw a couple of people having similar issues with 2400 and Fiocchi primers. I plan on pulling the rest of this batch of 50 just for good measure. Any idea what's going on here?

Any idea what's going on here? ***** Never had a problem with Hercules 2400, nor newer generation Alliant 2400. Never fired a Fiocchi primer. (Exception: Fiocchi factory ammunition, which I don’t care for.) A degraded primer----prior exposure to moisture or inferior manufacturing----may ignite enough to push the bullet out of the case and across the barrel/cylinder gap, where it stops it against the rifling. With a standard gap, the bullet may be seen straddling into the forcing cone. The bullet must be pushed back into the cylinder with a wood dowel or brass rod. If the rod is aluminum or steel, it should be taped to protect the rifling, especially at the muzzle. A primer may not possess the blast to ignite powder, yet exert enough pressure to push the bullet into the barrel/cylinder gap. The same load or burn characteristic will jam a bullet in the rifling of an auto pistol. Sounds like bad primers. As for your load, a Hornady 158 XTP or other bullet of proven accuracy makes for a low pressure, very accuracy load when seated over 12 grains/2400 in .357 Mag brass. David Bradshaw |

Like Bradshaw I'd say bad primers.

Bad primers and / or exposure of the rounds to WD-40.

Thank you gentleman. My suspicion is that it is a bad batch of primers. Odd thing is they are from the same sleeve of primers that I used for the last batch of 50 I loaded. These have never been near WD40 so that's not a factor. Now I have to decide if I should trash the 800 or so primers I have left, or gamble that these were just isolated mismanufactured weak primers.

If I was in your spot, I’d call Fiocchi and let them know you’ve got a box of bad primers. Fiocchi may even compensate you with a new box. Even if you have eat the price of new primers, bad primers cost more in the medium to long run. |

WD may weaken primers but it won't kill them. Had a bunch of ammo given to me and pulled it down one winter. Primers as explained to me "should not" pop when decapped. I err on the side of caution and load and pop them. I had sprayed WD or some other solvent in all of them. Went to pop them off figuring nothing would happen. Went over to sump pump hole in the basement, and dropped the hammer on one. Lol, it stirred the natives up stairs real quick.
On the Fiocchi primers and others from abroad. When things got tight on primers a few years back I picked up several K of what I could find. They all seat pretty hard and they all seat deeper than American made primers.
Dunno how you seat but even if they are flush they may not be full seated.

I don't know where you live but could have been a salvaged case/pallet from the recent wetness last year and pulled out of a flooded warehouse.

I bought them in New Hampshire over the summer. I was about 500 into a brick of 1500 when this issue popped up. I disassembled the remaining 38 rounds tonight, and there's nothing visually I can find wrong with any of them. |
