That was 1 hell of an extensive ballistic test and I really appreciate it.

It seems like the perfect self defence round. Accurate, lower recoil, penetrates vests, dumps energy, doesn't overpenetrate, is reloadable, and comes with 19 or 49 little friends.

I am an engineering physicist meaning I do a lot of testing for product improvement, knowledge accumulation, and proof of concept. I will say you have done an excellent job with your testing setup especially considering you are creating and conducting the tests, video recording this, and processing the data all solo.

Great video and testing effort, that is a lot of work! Don't apologize for video length, I appreciated the detail.

He is steady on the 5.7 game

Thanks for the thorough review. Glad to see speer supporting the 5.7

Video did not get too long. There is no filler in this video it's all good stuff.

I’m really digging this cartridge more and more…keep up the 5.7 content sir!

Love the thorough and in depth testing.

The amount of work, effort and info you put out there is second to none! You the man Matt 👍

*Matt, I really enjoyed your Kermit bent over imagery.*

This is one round I’ve never under stood , but I do appreciate all the work u have done to make the video

Very helpful, thanks Buffman!

Sub’ed to your channel as your one of the only people who tested in multiple barrel lengths and considered many variables. Most other just shot out of a pistol.

Great vid!

Thanks for the video!

Buffman range your 5.7 series of videos got me to subscribe instantly as I just picked up the ruger 5.7 and am loving it I have carry the speer gold dot in alot of calibers of the years so when I saw a box for the 5.7 I grabbed em this is after ammo has got a lil more available and back to non buttfn prices I paid 70 for 50 rounds

Thank you for the testing that you do.

Love your content! Keep it coming!

Upvoted just for that bonkers intro to the ammo box Lol! Also for the excellent as always testing and recording of the information, of course.

Great video. I know everyone thinks brevity is all the rage these days, but I appreciate the in depth video. I especially appreciated your dbx57 video and the takedown of it.

Awesome video, keep up the great job.

I’m ordering boxes Now!!!! Buffman my brother!!!!!!

Nobody does 5.7x28 like the Buffman! I love your work.

You do some the best work for the 5.7 round and I loved it when mr jay wolf mentioned your name. I am just hoping mr wolf starts putting out so help for the Ruger 5.7 but who knows .... keep up the great work and thank you

OH YEAH BROTHER!

Well, it turns out that they used an intermediary pistol powder on the slower end so the gains in the longer barrel are there, but not for the rifle lengths. Performance is arguably better than the 40gr ballistic tip ammo from FN and the boutique reloaders. I saw this stuff for $65 the other day. It's likely gone by now! It would seem that CMMG is the ticket with these and most 5.7 ammo. At the end of the day, nothing beats handloading! Great video, thanks again Matt! Edit: I got a response from Speer, and they say that don't offer and didn't have any plans to offer this bullet as a component...but the rep said he'd pass it on to engineering. Still haven't heard from R&R about the R37.X bullet 🙄

Got a like and a sub for all the work you put into this. I’ve Ben looking for a video that didn’t just talk about the rounds

Thank you, very informative!! 💪💪💪

amazing and very thorough test thank you for the hard work

So glad to see this. I shoot both a PS90 and a Ruger 57 and would love to find the best load for each of them.

Great test vid. Thanks.

Another great video. This should be named the 5.7 Channel. You are the man on 5.7👍

Very good Video. Can’t wait to get some to shoot!

Great video sir. I've been doing research for days on what ammo to use for AP and it's good to see that the speer gold dot performs in that way. Thanks for the leg work,

thanks for this video, was looking into the round's capabilities

aWeSoMe pReSeNtaTiOn...FuN.......Thank you for taking the time and energy for all our questions. The 5.7x28 gets my attention because of the lightweight handgun and its high capacity. Different and Unique. Worked 7 yrs on and off with the CIA and FBI six years. Toyz... PEACE

Dang i was hoping for a 1776 velocity. The speed of freedom

Great video very informal thank you.

Great impression.

$80!! Guess I got lucky $47 a box...I was limited to 2 boxes though. Thanks for the review. I had been looking around KZfaq for a review on the 5.7x28 Gold Dot.

Great info. Well done

Awesome vid brother. I appreciate your attention to in depth analysis. Could not fully understand what type of rd extension you had with the Ruger 57. Would you please reference it once again ? All the best to you. Keep up the stellar work

Lot of work and great test. You must be a fan of the caliber.

The FN Five Seven is really a do it all bullet! The Speer gold dot ammo is great for hunting and self defense. While the SS190 can laser through a armored helmet. This seems like a great tool that can fill so many roles.

Wow! That 5" Ruger pistol barrel was def that best as far as averages. All tests were right at 17" with it. Plate, denim and uncovered.

Great vid. Got a S&W M&P 5.7 recently and looking for a good defensive round for it. Thanks for the in depth vid. 👍

Mind the Monkey doll falling at 25:50…. This is very good ammo nonetheless. Loved how your channel has become more Refined over time.

Buff-o-mania brother.. 😎

Macros: flic.kr/s/aHsmRgRZTo

Their out!? Been waiting.

I like the ss198lf best for my 5.7 do it all. ss195lf would be my 2nd choice.

These rounds are deadly.... I took down a doe at 30 yards w/ my Ruger 57 using this round!! Thanks for the video it was one of the reasons I chose this round to hunt with.

Loved the Randy Savage!

Velocity of 4016 feet per second wow those really are super ionic ammo ! 😯👍🏾

Okay kermit the frog bent over was hilarious.

Randy's coffee cup promo is gonna live at least another 50 years!!

I’ve always loved gold dot ammo. A loooooooooooooong time ago when I got my first g19 (about 20 years ago). I actually used to use gold dot at the range quite a bit. I’d say 50/50 with ball ammo. Now there’s now way in hell I’d do that. But you do have to practice with your actual self defense ammo to know how it performs.

Them cmmg 5.7s ... Sexxxy af bro. I knew you were gonna pull trigger on one!! Lol. Sucker for that 5.7 lol. But yea I mite go for the upper/3 mag deal

Lovely. The permanent wound channels look very similar to the 55-grain .223 Gold Dots I tested a while back. Killer footage.

Great job at testing this and for spending the time to create it. But yeah this caliber is just not designed for expansion, it is designed for penetrating them tumbling within a short distance. Hitting that golden 2000 fps with a quality 5.7 ammo type for tumbling is what does the trick. If just wanting to punch small holes then use these very expensive hollow points. May as well use the very underloaded FN blue tips in my opinion for this performance.

Badass video (as usual) badass lil round!! That CMMG has me ready to spend the cash on one.... Id love to see you pop a few open and reload a little hotter just for shits and giggles! Thanks again

i bought this stuff 2 weeks ago. been waiting on a review before trying it out myself.

Nice job

Been waiting for this! I thought I was the 5.7 guy.. No.. it’s definitely You! Great vid!!💪🏻💪🏻 Edit Little disappointed with this ammo, going to stick with the Green tips and Black Dragon Fangz

Wow that round really penetrates a little too much for my taste. I was so looking to getting a box bbn or two of this round, with what I saw in this video it's off my bucket list damn damn damn

Love it

14:06 these new 5.7 loads are screaming fast. You're getting .22-250 velocities out of these babies haha

For feed problems on the ps90, clean the feed lips on the magazine. The powder that blows back pollutes the feed lips inside the magazine. It doesn’t stop feeding, but slows down the next round from dropping into place on time.

Excellent production values on this video. Very comprehensive. If you have it, I would love to see your testing of the PSA Rock 57.

Like any non "2nd gen" gold dot, this stuff is impressive. I was very fortunate to score 62gr. component bullets for the AR a few months ago. My gut instinct was to hoard, but I resisted. My 200 should last a while. Accurate too. Only took me about 30 rounds to find my load.

AAC 5.7 ballistic tip performance is the best 40 gr I’ve seen so far

Buffman: Ok, Mr. Chrono. I just need to gauge 1 shot. I'll place it right down the wheelhouse. Just gimme a velocity reading. Chrono: The velocity is FUCK YOU. That's what.

80$ ooofff..great vid

Who else was hoping to see a velocity of 1776?

16:52 Canadians: Nervous laughter

Amazing into 😂😂🤪

Steady rocking keep clocking lucky you for getting the ammo I so desperately need and seek but am not willing to do a Kermit the frog move for

Excellent video I have been waiting a long long long time to see something like this. Not the Gold Dot ammunition but the difference between barrel lengths in gel and other obstacles. It tells me what I heard 10 years ago but never seen a video on. 5.7 ammo is most optimal out of about a 10 inch barrel and extra barrel length doesn't really gain you anyting significant. So I am sold on an 8 or 10 inch barrel for my next 5.7 firearm. Is it going to be the cmmg or the new Kel-Tec p50 ????

I got it almost right about the speed XD nice. You should try the R&R IS132D-v3 , I think it use a 32 gr Lehigh Controlled Chaos.

A 5.7 PDW in an MP7-style design would make a pretty amazing HD gun.

Crazy stuff. Interesting that the shortest barrel (ruger) had the deepest penetration in every test.

I think they need to spice up the 5.7 gold dot abit. Would be better if it was 2000 fps out of the handgun. I think it would operate better out of the PS90 too. Still, it's too expensive for what it offers. As usual, great video! Thank you for all you do!

Great video I’d really like to see the windshield glass test The only thing I’d add would be windshield sim and interior barrier pen à la sage dynamics Speer gold dot testing video in 9mm This has definitely changed my mind a bit on the caliber and especially this loading with the metal and armor test Honestly the bare gel test is a little underwhelming but can’t really do much with 5.7 I just expected it to mayyybe be loaded a little hotter for being a 40 grain I’d have liked to see it towards the mid 1800 FPS range

No wayyyyy they brought them out!?!?!!!!!!!

It was to be released with the Ruger and it was not. It should be available for a normal price from a shop.

Thanks for the video and thoroughness. I have no interest in 5.7, but if I can get some of these bullets I could load them in my 22 hornet and it looks like they would perform well given the velocity and gel performance

I know doing the SBR on a PS90 seems like a "should", but I don't think I would. I like the longer barrel and it's still an extremely compact system.

Once I get a 57 I think I will be running the black fang because of your recommendations but this round seems to have potential as well. You mentioned the R37x at the end do you think the R&R round is more effective than the Speer?

*Oh YeaH*

Those eyebrows are pretty buff!

Hopefully, Speer will offer these as a reloading component, I would love to try these in my 22 TCM and 22 Hornet.

Disappointed with regards to PS90 reliability.

Matt, I have often thought. Why is there no Barnes TSX 30-35gr 5.7 offering? After seeing those GD loads blow through IIIA. That maybe why... Just always figured a light weight Barnes pill would work well in this caliber. But perhaps it would work too well. Keep up the good work.

Chrono hit my favorite year 1999 lol

Man I don’t know, those 40 grain American Eagle shoot great out of my 16in PS90.

Thanks for your video. Was just about to pull the trigger on a PS-90 purchase. Now a no go due to the malfunctions with heaver ammo.

There’s something that absolutely blows my mind about the 5.7x28. A superior round was developed WAY back in 1963. It used a far more common case, fired 35gr FMJ/HP at 3,000fps from a 18in Barrel, and can be used in both handguns and a very common milsurp rifle. Allow me introduce you to a cartridge way ahead of it’s time. 5.7 MMJ, or .22 Spitfire. It was based off the .30 Carbine round from WW2. It used common cheap surplus M1 Carbines, and it only needed a barrel swap to convert it. It was even used in a pistol with great success by hand loaders and custom gunsmiths. I don’t remember the exact name. It was made by AMT back in the 90s in .30 Carbine. Gunsmiths converted it to .22 Spitfire and the only down side was the bullets wouldn’t hold together. Why? Because the bullets that were used at the time couldn’t hold together at those velocities. BUT, I think now is the time that .22 Spitfire makes a comeback. I think we should try it with 5.7x28 bullets and see how they hold together in a pistol and carbine. Given the velocities achieved in the ‘60s-‘70s I think it would be the equivalent of a 5.7x28 Magnum. Assuming the bullets hold together that is. It would slot right between 5.7 and 5.56 in terms of range and power. M1 Carbines are still on the cheap side. Especially if you go with a good reproduction. Accuracy of those has been proven to be good, and they have a (relatively) large selection of tactical options available. Just look at the Inland tactical version as of 2023. With the right bullet and load development we could beat the 5.7 soundly.

Actually nvm my r&r u told me to get is way better and for the price ism I like the r&r u told me to get

Kermit goatzee is a new one
