great video!

couple of days ago I calculated that Br4 grade armor of SiC panels is 300 grams per square decimeter. It means that 75kg 175cm man can be armored besides legs and arms and this armor will weight 22kg. also counted Br2 UHMPE pressed panel (like Level 3) and full body with limbs can be covered by 9kg of it. Progress in armor is quite rapid.

I browsed internet sites where fiberglass panels for security rooms showed. There was grades of protection and thicknesses written. So I calculated that fiberglass panels are almost equal to armor steel by weight. but we don't know exact properties and what this panels consists of. It can be E-glass and polyester resin (which is cheap) or some other resin (epoxy is stronger than polyester resin) with additives which increase impact toughness twice (Fortegra resin).

Awesome video. The bullet on the left is the Buffalo Bore 454 Casual, and the right side bullet was the 350grn 460 SW. I shoot the 454 hard cast and it is on the left. But again, awesome channel and great content.

So to do an entire car you'd probably need to take out a loan?

I would consider the S glass as having stopped the .308. No lead passed through and it looked like the backface deformation was less than 44mm.

If you were to use the S and E glass together which would you put up front?

Is that Ruger Go Wild an actual 24" barrel or does that include the brake?

So still no John wick bullet proof vest I’m assuming….jokes aside it was entertaining. May I ask if you ever test polycarbonate?

It’s expensive, but have you tried carbon fiber plates? Either alone or with other materials?

In your video, how long is your barrel?

How many layers did you put in plate?

🇺🇲 Good experiment! Keep testing different materials

Actually really cool you were able to achieve 3A plate, good to know how to make

Sharpining stones are silicon carbide, I was thinking about buying a case of them from China to see how they work...pocket stones are only 1/2 thick, with a fiber backer I think it would work well

Berger next awesome video

This is exactly what i wanted to do with tile, but put it over the regular steel 3+ plates maybe with kevlar tarp and resin between but that'd probably be kinda heavy

When you measured your group did you subtract the bullet diameter to get a center to center MOA according to match scoring or is the gross spread. If gross spread, subtract.284” to get your MOA.

Federal Terminal Ascent is an amazing hunting bullet for big game. I load the 155’s in the 7mm Wby Magnum at 3,301 FPS.

Proves again that the ELDX bullets are junk!

I’d love to see your build

Between the Hornady and the Federal which one would you recommend

HDPE in solid block form doesn't really make any sense... The material structure is very different to layered UHMW HDPE, where all fibers are only bidirectional... The fiber direction in these solid blocks is all over the place...

At 3:25, with the pill hitting the fiberglass, there is a green flash. What is the flash from?

Can you compare S-glass vs E-glass vs basalt composite? basalt AFAIK is strong as E but tough as S

I waited to see S-glass against bullet and now I saw it but I didn't get what you said about it.

it bulges so well that you can use it against RPGs as NERA armor like Chobham/Dorchester.

Too bad the 170's are impossible to find these days

How heavy is the plate?

would be nice to see a build of a standardized plate using these new level 4 protection material combination. also makes me wonder if there is something that can be done to stop those huge bulges on the inside of the plate, because like you said it yourself - you are not walking away from those blunt force injuries

Are the tiles 1/2in or 3/4in?

cool bro

I'm going to guesstimate 45 layers of E-Glass for 5.56 and 308 FMJ. I'm surprised that the gorilla glue performed so well. Very informative, thank you.

I don’t get what the purpose here is. It’s your life, if you don’t have body armor because you don’t want to spend the money well it’s affordable if you consider that it’s life/death. Getting body armor just needs to be a priority, but it’s certainly fun to watch. I liked/commented to help out. Maybe you spin it as making affordable plates that can be placed in the car door or under windows?

Where did you get the uhmpe from. How much was it?

Sandwich the steel with the fiberglass and encased with the landscape fabric would probably work better.

Please make vid of the building process, this armour is just so good

I would love to see all copper loads go head to head in your rifle. With velocity, expansion, accuracy

yes for build process

Nice content! I'm thinking about adding the 7PRC to my already overflowing gun safe (it's a good problem to have)! A couple of observations...I prefer to chronological ANY factory ammo I shoot for hunting or otherwise. It's just better to have more data than less. Couple that with the advent of high BC projectiles and range finding options and we can literally remove elevation from the accuracy equation. Also and I think someone mentioned it...that shooting platform probably effected your accuracy a bit as did a little bit of inconsistency with your trigger hand grip. Hell, our heartbeat can effect our accuracy as much as an 1/8th of an MOA or more. Great stuff. Keep it up!

Lol, testing the first plates backer design in my next project basically, with the addition of carbon fiber. Supposedly the UD aramid does better with backface compared to the PE, do you feel it helped any? Also, where did you source the UD aramid?

I’ve spent my adult life trying to get a follow up shot to go through the same hole. This guy does it with a pistol. Ridiculous.

Why? 7PRC is rated for 900yds. If you want 1000 or more you need the 300PRC.

Very cool. How would you mitigate back face deformation on builds like these?

something worth trying could be allu + fiberglass as a backer, as fiberglass is stiff, and so will give structural support vs plugging method (in a similar fashion as one of the samples i build and tested with techthisoutmeow last year, where 15mm of 7075 T6 + 6mm of 6061T6 backer, where the backer kept the 7075 t6's plug in place and prevented penetration)

nice performance! would it be possible to do an alternative version where the ceramic is replaced by a quarter inch of ar500 steel (but same composite backer) to see the difference against the AP rounds?

Would like to see a build video on this one. Thanks👍

IF WE ARE STILL HERE????? yes we are waiting for that build. great show.

It's honestly impressive how far this channel has come from such humble beginnings. Good job and presentation.

Great Video, I would like to see the build video as well.
