Probably one of the indoor ranges close to me.  Gotta get some ammo and get back from Harvey 1st.  Thanks for the mag link.  Why were they made as 30 rounders?  For Illinois or something?

FN has made 30's and 10's as an option for a long time.  30's never made much sense to me. IIRC Ohio used to consider any magazine over 30 rounds a machinegun by itself, so it was probably to comply to with stupid laws like that.

Wait...you really think that if the police came and said "dear Arf member,we need help shooting looters" that having to use personal ammunition is somehow a stumbling block? There are 100,000  people holding a billion rounds of ammo on here waiting for the off chance that rioting occurs in their small town whose largest civil disturbance was a football game brawl in 1977.

They are pretty close performance wise. Bullet selection is more limited for TCM though, especially the 9R version.

I think if you could get a 30 grain Barnes bullet going 2200 fps you might have something if it can reliably penatrate 12-18"

Maximum Overall length....

5.7x28 - 1.594

.22 TCM - 1.265

The .22 TCM cannot reach the velocities of the 5.7x28 for several reasons, one of which is its crippled by its shorter overall length. It cannot use the more efficient bullets used by the 5.7x28. The weapons that utilize the .22 TCM are heavier, larger, don't hold as many rounds.

It also doesn't have anywhere near the penetration of the 5.7x28, not even close.

There are many more companies offering 5.7x28 than .22 TCM.

It might help if you used real world numbers



Something like a a Glock 21 in 22tcm might be interesting.

If they are getting 2100fps with a 40 jhp out of a handgun just think what they could do with either a bonded 40 grain so, or a lighter Barnes bullet.

Iirc the 5.7 gets the same velocity, but with lighter bullets

Eta, looks like 34 grain bullets from the 5.7 go about 50fps faster

Yes armscor is obviously posting lower numbers than everyone is really getting.

That 28 grain bullet you posted also does not reliably hit 12" after 4 layers of denim.

As I ve stated before I could care less whether you or anyone else likes the round or not, anyone can clearly see the .22 TCM can't reach the velocities or penetration of the 5.7x28 and now that Elite is selling DevestaTOR to "Joe Citizen" it's not even close!

DevestaTOR out of the FiveseveN penetrates four Level II vests AND a CRISAT plate.

An average doesn't mean much when 1/3 is below the minimum accepted standard.

What's the velocity of 5.7s using 40 grain bullets? The .22tcm is new with one loading. I see a bunch of potential with it. Especially in glocks, m&ps, etc.

I'm still waiting for you to post 5.7 loadings that reliably meet the FBI standard 12-18" through bare gel + the 3 barriers that I've asked for in a different thread.

I actually cut up a 30rd PMag for a brass catcher. Being in Colorado, it was not an easy decision to make, but I think it was worth it.

No baseplate? I have reliably caught all 50 cases in the pmag. Still haven't figured out why all the necks are severely dented though, catcher or no catcher. I have no intention of reloading anyway...

Yes, they are. I don't know why, but they are. Everyone who chronos the 22TCM sees at least 2000 fps in the real world out of a pistol.

I think one of the only things holding the 22TCM back right now is the poor marketing by ARMSCOR.

It is similar to 300 Whisper vs 300 Blackout. The Whisper was a niche cartridge for many years, but once a good marketing company got a hold of it (AAC) it took off. I expect something similar to happen with the TCM, it is just too good of an idea.

I really like the 5.7x28mm and I think there is plenty of room for both it and the TCM, I don't see it as a competition really. The long OAL of the 5.7 gives better bullet selection, while the short OAL of the TCM gives more flexible selection of guns and magazines.

My duty rifle is loaded with Hornady .223 40 gr TAP Urban. I can pretty much assure you it won't go 12" but it will leave a permanent cavity the size of a grapefruit around 5" in. Think that won't stop a dirt bag instantly? The load is in use by several large SWAT units around the country. The track record is a hit to the torso and their down, body bag down.

I do carry TAP Barrier in case I need to engage a vehicle.

22 TCM VS Level II Body Armor


I know how you hold the FBIs standards in disgust, which should be a sign for the rest of us. While I'm a no one, I have shot people with a 556 and I sure as hell wouldn't want a round that penatrates so poorly. I suppose your experience shooting bad guys must be different. Good luck with that.

I think both these rounds could be kick ass if the 5.7 could actually show how they perform against the industry standards, and the .22 tcm needs more loadings. Just from the one tcm loading it looks like it shows a lot of promise if they can fit it in a few other polymer guns.

I'm surprised someone whose spent 30 years fighting bad guys doesn't favor more penatration. Hopefully you'll never need to test your theories.

I always thought you needed the gel or clay (or a body) to back the soft armor because that firm elasticity improved its performance.  Without anything in back I think more stuff gets through.

Other way. A loose floppy piece of soft armor is much harder to penatrate.

Picture a piece of paper. One backed by clay, the other hanging free. Now poke your finger through them both and see what happens.

The thought is the bearing surface on the Federal AE bullet is too short to properly retain the bullet in the case.

Reports indicate it works better in the FiveseveN pistol than in the PS90.

If the 5.7x28 AE failures are so wide spread, I wonder why Federal isn't doing something about it.... Are people not contacting Federal? It seems Federal could have thousands of complaints if everyone that had a problem contacted them.  I want to buy about 500rds of the stuff to try out in my PS90 since there are many people that have zero problems with the stuff, then there are people that make it seem like I'll be dead on the floor of the range if I use it or at the very least I'll have over half of the rounds set back into the case. What are the variables in the PS90 where some people have nothing but issues while others have no problems at all. I've used tons of American Eagle ammo in other calibers and there's never been inconsistent quality from one batch to the next. Is there a simple crimper a non-reloader could use on these rounds?
