I've been buying all the Tulammo steel case in .40S&W & .45ACP that I can get my hands on. The accuracy is very good shooting it with my Gen4 G-21 & G-22 . It's dirty as all get off, but you can't beat the price! I'd rather shoot Fed American Eagles, but it's hard to find, one LGS here is asking close to $30 a box for Fed AE in .45ACP, the Tulammo is almost half that much, so I shoot twice as much, and my G-21 shoots it really well. This is definitely good enough to shoot targets with, and these Glocks are not picky about the ammo you load them with for practice, which is the thing I like best about them.

Much easier to find in a search. Thanks.

I'm told that because steel does not expand and contract as readily as brass that there's a lot more breechface and chamber leade area errosion. I, further, understand that steel cases wear out extractors much more quickly than brass. Could any of this be true?

Steel does not seal around the expanding case as well as brass, leading to errosion in the chamber...after a gazillion rounds.

The bigger issue with that cheap crap is quality control. Funny how many pics you can find of blown up guns in which the owner proudly proclaims, "It must have been the gun because I'm using factory ammo". If that "factory ammo" includes the crap being made by some drunk Siberian in a factory with a leaky roof, I don't have much confidence that the ammo wasn't the issue.

Were you aware that much of the copper jacket Russian crap is actually copper plated steel jackets? Yea, that's good for your barrel.

Bottom line: You get what you pay for, and when I see some hickerbilly shooting a High Point C45 with Tula ammo, I stay as far away from that guy as I can.

(1) Not really. About five to six thousand fired rounds will more than do it!

(2) Yes, I'm aware of that. Thanks! :)

I don't know man.. I've done some tests on pistols with different ammo, and the Tul and other steel case don't cause problems in pistols that I've used.. Especially in external extractor guns. GLOCKs, and other modern pistols eat it up(Especially a G21, they shoot as good or better than some mid level 1911s do- FACT)...

I also have shot a bunch through AR, AK, and HK rifles now. There is an extensive test on ARs online somewhere that I could dig up.. .Not sure if you even want to see it on a pistol forum though. My point is that if rifle pressures don't wear out breeches and chambers. There is actually LESS erosion near the gas port on ARs than you get with others like Federal and Winchester. You may get extraction issues, but there is a VERY simple upgrade to fix that and ALL the ARs I've seen with that issue were cured with that O-ring upgrade.

On the pistol side, I had issues with a couple low end 1911s feeding steel case ammo, but once broken in, they ran fine with it. I have yet to see a GLOCK, XD, or other modern pistol that won't eat it up with aplomb... I have a 2 pin G19 that has eaten unspoken amounts of it. That's a personal gun, too. It might be well maintained, but it's been through the fire.

A third generation Glock Model 21 is my EDC pistol. I got it back in 2003; and have since extensively rebuilt it. There's no way I'm going to run ComBloc ammo through it!

The new 3rd and 4th generation G-21's have MIM extractors in them. They're softer, sloppier, and don't grab extracting cases anywhere near as tightly as the older machined steel extractors do. Consequently I do NOT look forward to the day when I have to replace one of my old steel extractors for one of Glock's crappy new MIM extractors.

Wal-Mart's, 'Federal Champion' ammo is reliable and cheap enough; besides it has none of the reported faults of foreign ammo. Were I still firing 1,000 - 1,500 pistol rounds each month, I'd probably go back to reloading. Here's one of my G-21's ~

Now we all know you must be hallucinating. If Gaston were available, he would certainly assure you that such is IMPOSSIBLE due to "Glock Perfection"! :D

Just an observation here after 20 or so years of gunsmithing...

1 If your gun wont eat ammo that might be the only ammo available in a bad scene, you don't want that gun

2 The more you "do" to a gun that has been extensively tested for use by military's around the world, the more trouble you will have.

3 There is a different world we all live in now, and I don't like it either.

4 Best guns for the money and this issue... Sig, Beretta, and the CZ and the Turk clones.

Just sayin..

Steel case and bi-metal bullets

I won't take the chance in my pistols. It's a fact that much of the steel case ammo has " bi- metal " projectiles. AKA steel jackets plated with copper.
Not in my precious target guns. If it was $5 a box I wouldn't shoot that crap. It may shoot well. The Russians and Chinese are more than capable of making reliable ammo. They aren't really thinking of using match guns to shoot it through though. I cringe at the thought of steel jacket going through the bore of one of my high quality barrels. I don't own no clunkers. That cheap ammo has a purpose. If you just want to shoot cheap out of mediocre guns it will work just fine. It is CRIMINAL IMHO to shoot it through a Quality firearm. But there are applications where it is adequate.

Not necessarily. I've got 35 to 40 thousand + rounds through two of the Glocks I've rebuilt - All without so much as a hiccup. I've got about 8 or 9 thousand rounds through a third, more recently purchased Glock. It runs well; but it would run a lot better IF I could find a decent steel extractor for it.

I've been gunsmithing for a long time, too; and I agree with everything else you've said. (Except I'd choose CZ, first, before either SIG, or Beretta!)
