I don't know how anyone can see what the 5.7 did to the clay and say that it would be ineffective. its changed my mind, I'm already looking to build an AR chambered in 5.7. I'm going to contact Robinson Armament and ask them to make a 5.7 XCR-L option!!

@@combatreadychannel I'm sure there's a NATO treaty prohibiting the design and use of such a weapon.

@@thatoldagencyguy Yup. Like CombatReady demonstrated on the clay, it's devastating. The stretch cavity blows out backwards through the entry hole even with 40gr FMJ.

⁠@@thatoldagencyguyTemporary Stretch Cavity is a function of speed, weight, and diameter. Temporary Stretch Cavities over 10cm are the ones that start to damage elastic organs in the body.

@@RageQuit003Clay is not a tissue simulant.

That’s true. The price difference isn’t that much different when we are talking about 9mm defensive ammo but the trade off would be target/practice ammo will be cheaper with 9mm so people may be able to train more. And shot placement is always king!

@@combatreadychannel So use a 22 LR for target practice.

An unfortunate example of how effective the 5.7 is.

It’s definitely on my short list

I’m still on the fence on which I think is better but the 5.7 definitely isn’t the weak round so many KZfaqrs claim it to be!

​@@combatreadychannelI got the Rock 5.7 dirt cheap and because one day I'll score the ammunition that makes this weapon Golden. Having a pistol that can take on armored gestapo thugs intrigues me .

It's $0.40 a round. Have you tried not being poor?

​@@magicstix0r I haven't seen it less than a buck. Especially during COVID. I'm gonna double check but I don't believe it's ever been just .40 cent let alone recent years.

@@robertyanez4671Look on PSA’s website. In the 50 cents a round range

It really does show what kind of energy the bullet is capable of. It’s also cheaper!

Persactly is the exact word needed!

Is there any premium 9mm ammo less than a dollar each?........................elsullo

It was only a mater of time once more brands started marking their own 5.7 firearms

Good round for people who rarely practice. Which I suspect is most gun owners. not sure why 5th groups guys thought it was for them .meant for rear area troops and reservist who get bare minimum firearm training .

Did they say why they didn’t like it?

@@combatreadychannel They didnt like putting 24 shots in the same spot in under 5 seconds lolololololol. KZfaqrs are so silly.

@@driftedcowboy5941that does sound frustrating!😂

​@@combatreadychannel usually the complaint is the the mp7 and its variants .Not as much as the 5.7

It depends on the ammo you’re using. If you get armor piercing rounds then yes. That goes for any caliber. If you’re using hollow point or some other defense round then probably not but it also depends on shot placement.

By looking at ballistic gel test, 5.7 hollow point penetrates shallower than 9mm hp.

Other than armor piercing or possibly a 27 gr. bullet, the 5.7x28mm was designed to expend it's energy quickly inside the tissue and tumble inside the cavity. Using ammo with the 40 gr. V-max bullet stop the threat very effectively without hazard of overpenetration.

Coming soon!

I’m going to get several different 5.7 loads and see how the perform in an upcoming video.

@@combatreadychannel 🪖🔥🔥🔥🔥

Where do you get 67gr?

@@DodgersLH714 idk about that. 62 grain is common tho.

Sure I could "afford" that but 22lr already exists, see comments related to subsonic 5.56...

Do you even own a 5.7x28mm anything

@@rashardwalker9166 My post was specific to the ballistic efficiency of the 5.7x28. I'm sorry you missed that point.

I’m not sure which is better either. I did do another follow up video comparing the 9mm and the 5.7 with clay blocks. Both seem to cause some serious damage. I’ve never hunted wild hog before but I’ve heard that they are pretty tough and aggressive . Once you’ve giving it a try let us know how it does! 5.7x28 VS 9mm Part 1: Clay Blocks kzfaq.info/get/bejne/opplqqxpubeZpKs.html

I agree I rather carry 9mm than the 5.7x28mm,I've seen a few stories where it took guy 8plus rounds just to stop a attacker,that's sad/scary man 9mm in federal hst or goldot should do the trick with 2/3 rounds if you had to defend your life,with that being said I carry 357sig hst great round there,be safe,take care man.

@dreambig8996 Thanks. Yeah 357 Sig is great. Now if you step into Underwood +p+ rounds you are in 357 territory if you have a gun that can handle that pressure.

@@tradbowtimewithuncledan2686 my g23 gen 3 handles it well

@dreambig8996 I am a Glock Gen4 guy. I have a G17 MOS with a Silencerco G17L Barrel Threaded so right at a 7" Barrel. Running +p+ Underwood 147gr with the GoldDot HP it is delivering substantial energy. I have killed several 200 plus pound hogs with that setup. I can't remember the chrono readings but it was about 1300. Usually they will only take a few steps are go right down. I recently got +p+ 90gr in. It has the Lehigh copper screwdriver tip bullet. I plan to test that out. Should be over 1600 fps from that rig.

The main point of the video is to see if it has enough energy to be an effective self defense weapon.

Short answer is yes it does. I would not want to be shot with this! And the follow up shots... pheww!@@combatreadychannel

Lies

Maybe it is. I’m going to try some different defensive loads and see how they compare to the 9mm

Huge disagree. You're not watching Buffman's videos then, he's shown ammo that is absolutely lethal and the speed of follow up shots is stupid fast. Is it level with 9mm? No, but its very close. 18 inches in gel with 4 inch cavitations with lightning fast shots? You'd be stupid to believe that's not effective.

@robarmstrong5404 Lethal isn't the question. If lethality and follow-up shots were all that was required, we would have settled on the .22LR a hundred years ago. For all the hype on the 5.7, we have every right to expect more than mediocrity, and some of us don't plan on needing five shots to do the job. I am fine with niche calibers. But I lean towards 10mm Auto. If I require a follow-up, fine, shit happens. But it isn't Plan A for me. Our job is to stop aggressive behavior. Stopping is different than lethality. It doesn't take much to poke a lethal hole. Hitting them hard enough in the process to convince them they are done and have better things to worry about takes more than what I am seeing from 5.7. Hard pass. I have never been anything but underwhelmed by 5.7, even setting the bar pretty low.

Really? A doctor in my family who works in the ER will differ with you. He has seen it kill people.

@geminiascension7018 Lethality isn't indicative of efficacy for defensive purposes. A piano wire has killed people. That doesn't mean we carry a garrote for self-defense. The 5.7x28's lethality isn't in question. Its efficacy for defensive use is. The best 5.7 loads struggle to match the worst 9mm loads. The 5.7 is objectively inferior to other standard duty handgun calibers. That it can still kill is irrelevant. If someone is attacking you, you plug them in the chest, and they bash you brain dead in the skull with a brick before staggering off and dying, your round has been lethal, but ineffective. If you put a 12 gauge bean bag round on them and they instantly double over and collapse before evacuating their bowels and flopping around on the ground weazing until taken into custody, your round has been effective, despite its decided lack of lethality. As defenders, a cessation of hostility is the desired result. The 5.7 isn't as persuasive in this regard as other duty rounds, which is why it remains far less accepted in this capacity than the rounds it was supposed to replace three decades after it was created.
