I went to the range today after two trips to the Social Security office to get replacement cards for the youngest ones (Looong, NSFW story as to why they made me make two trips!). I brought along two 9mm’s; the CZ75B that I just picked up on Friday and installed CGW spring kit on Saturday, and my SA Ronin 4.25” 1911. Ammo was a hodge podge mix of Blazer brass 124 gr and Fiocchi 115 gr FMJ.
The CZ shot as expected at 7 and 10, but juuust a bit right at 15 yards. No bobbles with either ammo. (7 & 10 here.)
The Ronin was chugging along, firing a few magazines full of each brand. Then, while firing another magazine of Fiocchi, the gun cycled but didn’t feel right. I looked at the gun, it was about 1/8” out of battery. I dropped the magazine, which still had a round or or two in it, and tried to put the safety on. No dice. (Out of battery
!!) The slide was locked in place and would NOT move forward or backward under hand pressure at all, even pushing the front edge of the slide on the bench wouldn’t move it.
I put the guns in my case, went to the counter, explained the issue and the RO and I took it into the armory. Using a brass rod in the barrel, I tapped it on the ground, which dislodged the cartridge stuck in the chamber.
The bullet had broken its crimp and seated itself so deep in the case during the feeding cycle it swelled the cartridge case and wedged itself in the chamber.
I went back into the range room and loaded a different magazine with Fiocchi. On the third shot the round did it again, jamming itself in the gun. This time I dropped the magazine, put the Ronin back in the case, went home and tapped it out in the garage.
I realized when I got home I had made one error when I dumped the case of Fiocchi into the ammo can. For some reason I didn’t put a box-end with the lot number into the can. When I have an issue with ammo I like to let the manufacturer know, but without the lot numbers I can’t ID the ammo beyond the maker and caliber.
I have fired easily 3,000 Fiocchi rounds through my 9mm’s over the past couple of years, this is the first batch with compromised neck tension like these had. (I still have 1,500 still in the case yet to open.)
Blazer & Fiocchi unfired, the two compressed Fiocchi rounds:
Regular Fiocchi round properly seated in the Ronin chamber:
Compressed Fiocchi round seated fully:
As always; if it doesn’t look right, sound right and/or feel right; STOP SHOOTING!
Keep it pointed downrange. Put it on safe if equipped, unload the chamber(s) and any magazines if possible, and then safely check for the problem.
Stay safe.
