Remington UMC 124 grains, frangible.


October 23, 2013, 12:40 PM
I was hesitating whether to post this question here or in Handloading and Reloading, but given that it's not strictly related to handloading, I decided to post it here and see what comes out.

One of my shooting buds is using this ammunition. It's the Remington UMC, the one in the green box with the 124 grains semi-jacketed frangible bullet. I have chronoed this ammo in my Star 30M and got a Power Factor of roughly 130, make that some 1045 ft/sec. A bit less in his CZ SP01 Shadow. Problem is, this morning they've had a squib. Some other days they have encountered problems with primers that didn't ignite on first strike. Luckily, the guy who had the squib is an experienced handgun shooter and noticed what was going on, but go figure what could have happened if someone less experienced was shooting.

The problem with that squib, with those primers, and some other problems I've read about this ammunition, like bullets setting back into the case when being chambered, has driven me to ask here: Have you guys had problems with this ammo?.

The issue is not to be taken lightly since this ammunition is being issued to the local police force in my hometown. This guy is one of their shift supervisors and is concerned about this. He wants to gather as much information as possible and write down a report for his boss, so he has this ammo replaced by a more reliable alternative.

The "alternative" could be manufactured by Fiocchi of Magtech. Out of those brands, I've fired a few thousand cartridges and never, ever, had the slightest problem.

Inputs appreciated.

I've never used the Rem version.
I've used SBR and Fiocchi frangibles with good success.
I did have a few failures to fire with the SBR ammo because of the hard to ignite lead free primers, but no problems with Fiocchi.

I avoid Remington ammo/components.

If this is what you're talking about

it isn't semi-frangible or anything close to frangible. It's enclosed base lead core bullets, basically a reverse FMJ. The intent is to eliminate airborne lead indoors. Also uses lead free primers.

I have shot about 10,000 of those and I think I remember one dud. IMO it is excellent ammo.

If this is what you're talking about, disregard my previous post.

124 grains seems heavy for a lead free frangible.

Right, my mistake. Edited the thread since it's evident that those bullets are not frangible. My apologies.

Any more inputs?. Rifle reloaders that I know also tend to avoid Remington stuff. In my case, I reload 9 mm and I have notices the Remington brass to be significantly softer that other brands, Magtech or Fiocchi to mention two. But it's this primer failure and that squib that has got my attention.

Let's clarify here: are you absolutely sure that your local police are using the Rem/UMC enclosed base "Leadless" ammo? Because that would surprise me. Or are they using the frangible 101 grain "disintegrator" variant or some other variant available only in Spain?

I'm absolutely certain they're using the "Leadless" type. I know this guy well and some other officers who are employed by this agency.

I think I know why this surprises you. Not using hollow point, isn't it?. Authorities are reluctant to issue them here. Some local police agencies do issue them. Generally, those who have in charge of the logistics area someone who knows his stuff. The two agencies that operate at what you'd call "federal" level do not issue those except for the tactical teams (makes sense, huh? :confused::rolleyes:) and issue either semi-jacketed or FMJ to the rest.

Hollow points have a reputation of being more "harmless" and no politician wants to be tagged as a bloodthirsty type who wants to harm the bad guys more than necessary if they ever decide to harm the good guys.

Ridiculous. Though if I had to choose between JHP and exposed lead tip I'd probably choose the latter.
