338 Lapua vs 7mm RM vs 308 Win vs 6.5 Grendel On Steel 

looks like that second.308 shot around minute 5 was pushing against the vertical side of the steel sled v2.0

I’m impressed. I have owned and hunted with a Remington 700 BDL 7mm mag for 30 years. It’s never failed me. But when it performed on this steel penetration test nearly as well as the 338 Lapua, WOW

The 308 was 300 fps under the stated velocity because they aren't tested from 16" barrels. It had trouble getting through because part of your steel sleds was directly behind it.

I’ve owned a 7mm Rem. Mag. since I was 14 (and that was 50 years ago) and it has never let me down. You just showed why.

Thanks for the video,it's something not a lot of people have done

Thank you for doing this so much! this helps me with my decision on an AR10

Do not overlook the fact that the .308 on the 3/8" plate partially hit the reinforced steel sled. That will have absorbed some of the energy. Even at 300fps below advertised, it probably would have punched through if it hit plate only.

Oh and you have a new subscriber! Thank you for the time you spent putting this video together.

I like your videos! Keep up the great work!!

I'm enjoying your testing. Thumb up. 😎

Awesome video love the new steel sled 2.0 !

Good demo. I shot 3 holes through a 4" flange x 10mm thick, at 100m using 7mm Mag, 165gr federal. The holes were straight through. The flange was propped up on a wooden frame, which fell over when the rounds hit.

I have a 7mm mag and I love it. Have taken several long range kill shots. Love the flat shooting that it has.

Very interesting- i think at a 1000 yards the difference between the 338 and the 7mm would be alot different. Super cool video

Just found your channel. Very good content man. It's entertainingjust enough and quick to the point. Sub'd

❤ thank you, Midway USA! Obviously there is no affordable drilling, with 338 Lapua Magnum... But there's no denying the results

The 7mm is a beast. I starting to love my 7mm Weatherby more and more each day.

I've had a fascination with shooting steel since I was a kid. My grandfather had a friendly contest with a buddy of his back in the 1960's and after hearing about it I was hooked on the idea! After the Kennedy assassination I guess there were rumors circulating that the 6.5 Carcano was something of an oddity and had some supernatural ability to punch through hard barriers. The allegation was that it could shoot through a 'railroad plate'. Interestingly enough, they never specified what kind or how thick, as if somehow all railroad iron plates were the same. They most definitely are not. My grandfather's friend shot at this very unspecified plate and much to his chagrin, it's 156 grain bullet did NOT deliver and only dented the plate. My grandfather then tried his rifle, chambered in .30-06, which DID penetrate the plate. Since hearing that tale, I've been obsessed with the idea and science behind 'What about different cartridge and bullet combos enable them to do such things.' I apologize for the long comment but it was setting up my personal story of shooting Steel. I haven't had the opportunity to continue my hobby of punching steel for a couple of years now for lack of a safe and appropriate place to shoot, but the very best conventional bullet I've ever seen put up against steel was the Swift A-Frame. For some reason these bullets seem to be VERY difficult to come by as of late as even the Swift website has very few options available. The cartridge I used to achieve the best results I've seen to date was the .300 RUM. The interesting thing about the A-Frame design when compared to other conventional bullets is that they don't seem to expand as widely, even on mild steel. I've fired Core-Lokts in 7mm Rem Mag and even though they start out at .284" the expanded craters were closer to .70" wide but only about .50" deep, whereas the .308" A-Frame ended up only about .40" wide and .75" deep. It was a .75" thick plate and while the bullet essentially pushed the steel to its limits, deeply catering and even cracking the back side, none of my 4 attempts actually had enough gas to drive through. However, I don't think the 200 grain monster at 3,000 fps +/- is the best example and there's another cartridge I believe would have delivered better results. That cartridge is the 7mm Remington Magnum with either a 140 grain (at about 3,200 fps) or a 160 grain (at about 3,000 fps) Swift A-Frame bullet. I'm convinced that the 7mm's narrower starting diameter, coupled with the piercing ability of the A-Frame design and with the velocities obtainable from the Rem Mag cartridge, would be THE most likely candidate to punch through the 3/4" plate of any conventional bullet/cartridge design short of a .50 BMG. IF you're ever able to get you're hands on some of those bullets, I would LOVE to see them used in a video.

Looks like the 308 on the 3/8 plate hit where the rest was behind

Some of the best entertainment and science out there!

You have the sickest voice ever, fit perfect in commentary or radio.

Two 7mm comments: 1st: I used a 7mm RM for big game for a half century. While I never filled my Steel Plate tag, EVERY big game I took was a 1-shot kill. 2nd: Your 7mm shoots low and right. It’s no wonder you nailed the upright brace.

Pretty impressed with the penetration of the 7mm mag. 😊👍

Good video. I’ve heard that solid copper bullets penetrate nearly as good as armor piercing. Would love to see you add some copper bullets in 👍🏼

Thanks, Raymond.

Well done adding the 7RM everyone except Rex reviews forgets about that cartridge.

Awesome video !!!!!!!!!!!

The 7mm Rem Mag is tough. It appeared that it also hit against the upright as well. Wonder if that made any difference? Great video.

The 308 failed on the 3/8 inch plate because of where it hit. It was too close to the edge of that sled, the effect was like trying to shoot through the strong part of an I-beam (the vertical portion in the center), instead of the flat part.

Good stuff. Thanks

Great video

Very interesting test.

I have a 7mm rem mag and love it. Everybody I shoot with uses 30-06 and it doesn't have the same power or range as a 7mm. Downfall of 7mm is it's very expensive in my area. I can't find a box of 20 for under $45 it does get expensive but would never get rid of it.

.308 is typically tested using a 20” Bbl which would make sense for the advertised speed verse actual speed

Dam great video

Love you video's their a break from the normal gun stuff

What impressed me, was the low standard deviation of the .338 lapua round.

I would love to see you test the 264 win mag

it depends on the caliber and a 16" barrel on the 308 is not enough, it is better to use a 22" as a minimum. use FMJ if you can find them.

Nice new sled. May I make a recommendation? It looks like those plates are standing free. As you hit them up, I think they'll shift enough to chew up those "teeth" of the stairs. If it starts to look like the teeth are getting smashed a little, something to press down on the top of the plate just a little might help. And if I'm wrong, hey, no change needed! Always enjoy your videos. Thanks for uploading another!

A man, an arc welder, a legend.

New to the channel like the style

You would be surprised with a 22-250 and I have shot 257 weatherby into steel with amazing penetration. Speed does alot

Damn that 7 mag has me rethinking my next rifle

Grendel is strong for it’s size. The 308 was impressive. Probably would have went through if it was more centered. The big boys are what was expected.

4 minutes in. Can't thank you enough for spending the rounds... Great penetration video 🫦 You had me at standard deviation measurements...😂

You have have personality and make fun videos to make a great career 👍 ❤

Cool video

I love the grendel it punches way above it's weight

Great vid! Hope you buy some Lapua 250 grain lock base for the .338 Lapua - a stronger bullet and more velocity. I bet that would make it through 3/4" mild steel. My $.02.

You do realize you shot the .308 against the support for the 3/8” plate so no surprise it didn’t go through. Need a little more accuracy from the shooter.

Great video, i have a 300 win mag and i made a hole trought 1'' Hbeam, i think the 300 winmag has more punch than the 338 winmag.

I fired one round from a M1 Garand using a WW II production AP round that was standard issue ammo towards the end of the war. Target was a one-inch-thick piece of class A armor from a shop my dad work in just after the war. Just the tip of the core was showing on the offside with a lot of spall missing. I was shooting at 33 feet in the basement I got hit with a small piece of the jacket just below my safety glasses. Same round could go through a 18" diameter pine tree.

Excellent video again. 🎉🎈🥳💥 I'm thinking you need a little 1 inch fluorescent green circle to focus your attention on when shooting steel. Maybe a banana yellow circle? I know you're a better shot than that. Keep these scientific scenarios coming. Your channel is going to grow quickly.

Going to have to come back with a 5/8” plate to see how the magnums do there.

Is there a reason that you do t use 5/16 plate between the 1/4 and 3/8? It seems like you’d get a better separation of various calibers. For example stance when you did the 6.5 Grendel vs 6.5 Creedmoor, by your test they showed very close. I wonder if the 5/16 would have showed the difference better.

The similarities of depth for the 7mm and the 338 shots on steel, despite the obvious difference in power, is probably due to the difference in sectional-density.

Loved you're video. Get a 7mm Allen Mag and do the same test.

Watching this video really makes me feel like I was underplaying the power of my Remington 700 firing 7mm Rem Mag rounds at bowling balls years ago... might have to invest in more rounds and a slightly better rifle

My favorite gun channel and the only gun channel I hit the Bell on.

Good video. Thanks. Wanna try something different? Do a test run of the different “Accelerator” rounds. Example: .22cal bullet with sabot out of a 30.06 ( supposedly has blistering 4,040 fps)

Good job George I wished youd have added a 338-378 to your trial

Where did you get that cartridge shadow box on your wall? Super cool!

.308 needs more than 16 inches, minimum is 18 but you really need 20-24. This is why the difference of 6.5 CM vs .308 tends to have as wide of a gap, because people test the .308 with 16 inch barrel and use a 20+ with the 6.5 and go, SEE SEE, 6.5 is so much better. Same length barrel and best rounds for both, the .308 will have more energy till after 600 yards.

Velocity penetrates. When I was a teenager I would embarrass the “older guys” with their 308’s or 30-06’s by shooting through a steel plate with my 22-250 while their big guns would only crater them. It would be really interesting if you teamed up with one of the channels that has a super high speed camera and do some comparisons of the same bullet at different velocities on the steel you test on.

I wish you would have tried the 300 Norma Magnum (not to be confused with the older 308 Norma). It's my understanding the US military uses the '300' as its go-to long range sniper round using a 220 grain missile. The '300' Norma has a stouter case in a standard length action facilitating more powder capacity than a 300 W.M., thereby doing a good job with the heaviest 308 bullets out to 2000 meters (and beyond).

You should start shooting bananas at the end of every steel test. It would be a good gag for this channel

I have seen 338lm AP bullets Give it a google. Thanks again for the rad vids!

Nice video 👍 have you considered trying solid copper rounds? At close range with hot loads 300wm was able to penetrate through 1” steel with I think the round was Barnes triple shock

You used a HP on the 7mm. If you used Barnes solid copper, it would have been butter. Great video.

Got a test for you. Get some dry wall and build a "house wall" line the inside with rubber from tyre tubes both side then pour enough ball bearings (1/2 to 3/4 inch mix) in to fill it up. Wrap the excess rubber over the top of the exposed ball bearings so that when you shoot them they don't go anywhere. Find out which calibre would go through that.

You do realize when you hit 100k we expect to see a banana slamming steel at Mach 5

The reason the 7,62 didn't make it through the 9,525 mm plate is the suppressor. Take it off and the bullet goes down range 100m/s faster. That will clearly make a difference. Also the barrel of your gun is quite short with only 40,6 cm. That also has a huge impact on the muzzle velocity.

I wish you would do one with the 300 PRC. What would be neat is if you took all the prc's that they've got now and make a video. But I'm really curious about the 300 PRC. I know I'm not a patreon I can't afford. As a single father of two kids. But people generally don't respond to none non patreon followers.

I love the 7 mm Rem Magnum❤❤👍👍👍🙀

Have you tested out the liberty and munitions silver defense line? I would be curious to see you do comparisons against steels with defense type rounds.

Id say 7mm had comparable penetration in part thanks to higher sectional density than 338 projectile

I found that surplus 7.62x54r penetrates steel better than 7mm rem mag. Anxiously due to the mild steel core but I still thought the 7mm would have done better

Missed opportunity for a banana phone 🤣

Thanks.

You should try a 300 weatherby on 3/4" steel

I have a question what happens when you load a m855 bullet (green tip) into a hotter case like 22-250 or 220 swift ?

Nice intro👍

Need to test all with optimum barrel length if possible. The 762x51 will pass through 1/2" thick I beam

The two front posts of the steel sled V2 should’ve been sharpened like the V1. I don’t know why I had such an emotional connection with V1 but it will be missed🥲

Notice that the 7mm was NOT a FMJ? Coming in handicapped, I thought it rocked the test!!

2:00 the round and the description you gave was so cute. edit: i didn't know people hunt with this which I don't like. i hate the people who hunt.

My 308 (DPMS LR308 24" barrel) would punch holes in 1/4" mild steel tread plate at 400 yards using Federal Gold Medal Match 168Gr BTHP. I never tried any further than that.

Just getting into the 6.5GR and have been researching barrel lengths. Plan to use it for LR shooting and maybe some hog hunting. Was wondering what barrel length and ammo you got the 2600fps readings from? Thanks - great videos BTW!

Grind a knife edge onto the forward supports to split/deflect rounds.

So I'm here because I saw midway's comment on Facebook. Your videos look interesting I have subscribed but it would have been nice if Midway included a link to one of your videos not their website to buy stuff...... you know what I mean?

Suggestion : if you wanted to know speed and don’t want to waste ammo, just do it at the same time as when you shoot the plate .

Fun stuff. I think the .308 was directly against the frame of the sled, maybe give it another shot.

what brand is that 338 lapua rifle? its nice!

It would be interesting to see what damage the projectile or fragments will do after passing through the steel.

The 7mm has good muzzle velocity, but down range, a .300 WM carries more energy. Retest with .300WM

hahaha loved the silly intro. i dunno if he takes inspiration from Kentucky ballistics channel but it sorta reminded of his silly intro skits too

I was wanting to see just how far the Grendel would keep up. I love mine and it can take down bigger game then ppl would guess plus it doesn’t kick much.

Is there any lead in the bottom of the craters it would be interesting if you could melt it out

Bravo
