Short 9mm ammo

[Dinosaur1]

Sprung for a Sccy because the price was right. Hardest magazine to load I've ever experienced. Long trigger pull but I got used to it. Surprisingly accurate. Fits my hand. Light. That's my review in a nutshell. Ya git what ya pay for. I had 3 boxes of ammo, white box Winchester, Federal and Remington UMC. All standard 115 gr. hard ball. Worked great until I put in the UMC then it jammed every time. Would not extract. I lined up the rounds on the bench and all the UMC stuff was a good deal shorter than the Wins or Feds. The case head seemed to be rounded too so the extracter was just jumping over it. Anyone else ever run into this? There were 3 boxes of UMC and all were shorter but functioned in the other guns there. A Sccy thing maybe?

Like how much shorter? Do you have a micrometer? I put all my factory 9 in the same bucket to reload.

I put the mic on'em but don't remember the numbers. I'll have to get it out again. If I remember correctly the cases were only running a little shorter but the bullet was seated deeper and the case heads were rounded off ever so slightly.

Haven't run into that problem with any UMC 9mm. ammo I have. Did reload a bunch of 9mm. sometime back that was a little shorter than spec and wouldn't feed through a couple of my other pistols but the SIG P228 I had fed all of them with nary a problem. Could just be a something with your particular gun.

Pulled 5 of each brand of emptys and put the mic on'em. Not much difference in length. Average around .737 give or take. However, the rim on the UMC is rounded compared to the other brands so it would only partially extract maybe? Anyways, the rounds are shorter so they must seat the bullet a little deeper for some reason. I did notice tho that all of the UMC primers were bulged a few thou where as the other brands were flat. Any rate guess I'll stick with the Win & Fed.

I think I've heard before that SCCY guns are ammo picky. But if you run what they like, they'll go all day.

Interesting. The UMC, in both JHP and FMJ, runs well in my Kel-Tec PF9, a very similarly-crafted pistol.

If you have a batch of emptys around set them on a flat surface and see if the primers are bulged out a little

I've had issues with Remington 9x19 and .22LR. Simple solution..............I don't buy Remington any more.
Just remembered I have a case of the 9mm put away. Well, something else to sell.
