The Fastest Rifle Bullet (and the newest chronograph)

Check out Akek hunting backpacks at https://akek.com

17 rem at 4050 is my normal load, 19.5gr of 4198

This guy needs to get a 17 remington OR hand load a 22 – 250, 4700 is easy for the 17, and the 22 – 250 can get to a literally mile per second.

Why not a 28in 50 bmg with a .17 Sabot?

@4:08 You said you haven't changed your settings yet on the Labradar and you got a reading from the hunting rifle. That explains why you didn't get a reading from the pistol earlier — the Labradar has selectable speed ranges (handgun, rifle, archery) that correspond to 600 fps to 1600 fps, 1600 fps to 3900 fps, and 66 fps to 600 fps, respectively. You also need to set the distance between the barrel and Labradar correctly (6", 12", 18").

We made a load for 300rum with a 110 Hornady vmax for coyotes. Sits right at 4100 fps, kills the throat on barrels though

Have you tried a Bulletseeker chrono? As good as a Labradar but teeny tiny. No faffing about with tripods etc.

They did this a long time ago with 06 accelerators. Problem was they were terribly inaccurate

I've never seen an issue with accuracy on my magneto speed…. If you are cherry picking groups yes but over a significant sample size I have not personally seen a shift.

Do it again but use pistol powder…. Fastfastfast

Remington used to manufacture these for .30-06. If I remember correctly, it is very hard to get accurate results from these saboted bullets. Also, be aware that they may be illegal in some areas because they do not create ballistic marks on the bullet.

Stop a speeding bullet my ass

This is not a new thing. I'm old can't remember correctly but you could get the old 3006 with a sabot plastic and a 90 to 100 gr. Bullet.

Nice knockoff of stone glaciers quick release sling on the akek… support a brand that makes quality gear not the one that pays the most

I HAVE A CHALLENGE FOR YOU:
3D print a sabot for .50BMG and put a 7.62mm bullet in the sabot, the most long, graceful, smooth, streamlined, boat-tailed bullet (solid copper if you can get it) in the universe.

You will need smaller-grain powder to make sure the burn keeps up with the speed of the projectile, or you will be chucking lots of unburned cordite out the end of your barrel due to the mv being over a mile per second. Use cordite tuned in grain size for a 15-20 inch barrel. You will NOT build up excessive chamber pressure, because the super-light sabot and bullet will move far down the barrel much faster than a much-fatter and much-heavier .50BMG.

Heck, step right up and put it in a 48" barrel actual .50BMG barrel!

Don't worry about insufficient bullet stability, as the bullet at 5280fps will be turning FAR faster than the normal .50 BMG round!

Maybe use a mix of normal, large-grain .50BMG powder and smaller-grain shorter-barrel powder.

Will you originate and execute the world's first 1 MILE PER SECOND challenge?

Imagine the insane accuracy of a bullet that crosses 1000 yards in about 0.6 seconds. You may need a specially-shaped super-long-ogive bullet to ensure you comply with area rule better than a normal-ogive bullet.

Imagine a bullet that, if fired straight level, will only fall 62.5 inches in 1000 yards.

A benchrest-shooting revolution!

That is approximately 108,000 g forces of acceleration. You may need a super-rigid alloy for the bullet

You will only have 0.00075 seconds to burn the entire powder charge if you want it burned entirely by about halfway up the barrel.. What powders do you know that will burn at that rate?

The FACT is that two-mile sniping is only not done because people have been too lazy to advance the science, just like we could have had 747's in the garden of Eden, but, alas.

Not really getting those velocities from a .300 win mag though are you. It’s an over sized .22.

You have dead pixels on your camera. Love your content and analysis friend

You dropped some rounds on your floor lol!

i usually testfire with my springer air rifle to be sure that the chronograph is working. if a labradar needs more sound use a 22lr.
when you have limited amounts of handloads to test you dont want errors, and when you test the expensive cartridges.

Those sabots are one of the most inaccurate bullets you can select. I've even seen the varmint bullet vaporize and not reach the target.

I just don't care about barrel life for my varmit applications. I'll replace the barrel whenever I need, to get the speeds.

😈😈😈 good video 😈😈😈

Not bad, but 5500fps is a little better I think…
I’d post a photo of the magneto if I could.

Tell them that they need to use like an oled screen or something sunlight readable.
Mirasol display maybe or e-ink since there's no need for a big refresh rate?

224 Valkyrie is my pick for a fast bullet not resaboted.

Pls hw much of tikka t3x varmit.223

Those things didn’t even work and pick up the speed

Lol,backfire is a funny channel, waste of time. Audiose

Er Bulletseeker? It’s awesome, clips to your rifle, and talks to your phone via Bluetooth, non of that tripod stand and no external trigger either. Oh and if you’re interested it will work on an indoor range. You could probably clip it to a pistol as well.

One would think military snipers would sometimes use custom, hyper-fast bullets to reduce the chance of their target moving out of the bullet path.

Wish you would have used a .204 Ruger. I think that cartridge needs more love

To be fair, the Magnetospeed Sporter is only $250, and you can get a stock/chassis mount for the regular Magnetospeed that eliminates the weight on the barrel issue

The craziest cartridge and bullet combo i have seen and so wanted to try was a .50BMG cartridge with a sabot .30 caliber bullet of about 230 grain weight. The estimated velocity was about 5050-5150fps if i remember correctly.

Concerning accuracy testing and velocity testing at the same time with the Magneto Speed or Sporter. Yes you can, you can buy system to mount them via a picatinny or arca rail on the stock of the rifle. So, you see no POI change. I bought one of the first models out, but it was rather bulky. I, then, built a few of them which are rather lightweight and not bulky at all.

Hi from Australia , really like your channel , BUT what about the 17 Rem for the fastest cartridge .

22-284 with a 15gr monolithic bullet and 50 grains of 4227 powder is hypersonic. Please do a build. I'm sure Gavintoob will help you with a barrel

I didnt see an exit hole on that Stanley so it definitely stoped that bullet

Neat how fast they can shoot but how accurate over a distance are they?

Please do the review on that Bergara premier competition rifle the wait is killing me

Try this with a .338 Lapua

I love the 300 win mag. I feel like its the 1 ton truck of the gun world

Got a magneto speed

That was the same day i began getting reliable first round hits out to 1k on targets around 1 moa (max range available to me)

I laughed when your LabRadar didn't read. Those things are SO finicky. Biggest waste of money I've put into my channel. Sure it can work if you carefully dial everything in, but it's too finicky for my time.

Hey can you check out the CZ 600 Alpha bolt action rifle .. (they great !!) .. need more mags and stocks opinion

but still great guns thank you for videos.

Dude I’m sorry your wrong. I get my .204 ruger hand loads to 5,000 all the time. Been doing this for years. And your making a bullet to go that fast in a expensive way. Why not just max your .204 out and get 5,000 feet a second Hahahha

Spends thousands for radars and uses Kodak batteries to power them. Epic failure?
