Fastest known bullet speed?

[fatelvis]

After reading about bullet speeds over 4000fps on this forum, I got to thinking how much faster a bullet can go/has been fired. Has anyone ever heard of a cartridge that surpasses the 4000 FPS range?

Weatherby and somebody else hit 5000 fps. Weatherby did it with a 22 sabot in a 378 case. The other guy did it with 22-284 and a 37 grain iron sintered bullet. Matt

The depleted uranium M1 tank rounds muzzle velocity is 5500 fps. Like the 6mmBR it's very efficient. It only takes 18 pounds of propellant to reach that velocity.

A couple guys hit 5315 with a 20 cal. Bullet a few months ago. There was an article about it in trigger magazine.

I had my .220Russian doing over 4100 with a 52 grain bullet but it wasn't competitive and brass growth was horrendous. I slowed it down to 3700 and started winning and brass growth was manageable.

My 220 Swift hit 4500 fps with 36 grain bullets and 28 inch barrel. Think the bullets kept coming apart when varmint hunting. I slowed them down a bit.

Look in the older Hornady manual under the 17 Remington. Varget, 20 V-Max will get you 4400fps.

17 Mach IV/Fireball gets >4100fps with the 20gr.

In a good chamber, the 17 Remington should beat that 4400 number

4100 in my 6dasher is no problem with 55 nosler bt.

If you include anything the Dr. Gerald Bull's "MARTIET' was over 10,000 fps. Since an M1 was included I mention this.

and then there are the electric rail guns
4500 to 5600 MPH..YES MILES PER HOUR
8000 plus FPS

~ 6’ across, 18,000 MPH... hit Earth a few days ago.

Not quite aimed of course, good thing it burned up before getting to our level.

When the 220 Swift came out, factory ammo claims were 4100 fps with 50 grain bullets.

 

[Shawnba67]

Ive heard of the 22-243 breaking 5000fps with the old berger 30gr i think.

 

[mudduck]

The 30-06 accelerator ammo was supposed to be over 4000fps. Still have a box of them

I hear tell the 6.5 Creed is the fastest.

So fast no chrono can clock it.

So fast that if you aren't careful with your elevation it can reach low earth orbit and put you at risk of shooting yourself in the back of the head

It has to be true. Otherwise you can't post it on the Creedmoor worshippers website!

Careful now, the fanboys have a search app on their phones, tablets and PCs that instantly messages them when the word "Creedmoor" comes up anywhere in any forum on the web. Got to keep the hype going.

you guys have it all wrong,
it is the 6 cm that is fastest, regular light based chrono cannot clock it.
you have to use lab radar,
and yes duck every time you shoot.

A friend of mine is a scientist for NASA. He was telling me they have a gun that shoots particles to simulate objects striking the space station or other objects in space. Shoots about 4.3 miles per second. Not a rifle like we're use to but still pretty amazing
