Not sure how long the barrel is going to last, but +5000 FPS is "ludicrous speed" for sure.

<span style="font-style: italic"><span style="font-weight: bold">5000+ FPS with 22BR Improved and 30gr Berger Bullets</span></span>

Forum member XmarksSpot has been shooting a wicked fast varmint cartridge that has broken the 5000-fps barrier using Berger 30gr varmint bullets. That’s some serious velocity! The parent case is a 6mmBR, which is then improved and necked down to .224 caliber.

XmarksSpot reports:

Some people think 5000+ fps is mythical. Well just thought I’d let you guys know that I got 5239 fps a couple weeks ago shooting 30-grainers with my 224 McDonald, a wildcat cartridge based on an improved 6BR case necked down to 224. (This case is very similar to a 22 Dasher.) The bullet used is the 30gr Berger. (The 40s run fast too — about 4800 fps.) The rig is a Rem 700 with a 30&#8243; Hart barrel. Below is the case before and after forming. As you can see it has a 40° shoulder and far more case capacity than a 22 BR (a 22 Dasher case holds about 41.0 grains H20). My most accurate loads are with 50-52gr bullets, with bugholes the norm at 4200 fps. The 40gr bullets will do 4800+ fps.

This 224 McDonald wildcat was originally developed by Charles McDonald. He has been developing and chambering custom cartridges for years. Editor’s Note: Many folks may not be aware of the little .224-caliber 30gr Berger varmint bullet, and some online vendors don’t carry it. It is Berger stock # 22301 . It has an 0.119 G1 BC and will work in 1:15&#8243; or faster twist barrels. You’ll find more info on BergerBullets.com in the “Products: Varmint Bullets” section.
 
Re: +5000 FPS anyone?

Non trying to be an ass but what is the point? Is there a purpose for this cartridge? It seems it would be traveling too fast to be a successful hunting cartridge.

The 30's were just blazing and I doubt many rifles have seen 5000fps

Probably just did it because he can but it does mention that it will shoot bugholes with the 50-52 grains.

Like a guy with the fastest car at the track but he disconnects the nitrous for better run times.

not all shooting is about hunting, this can be a very good 600 yds benchrest laser,
 
Re: +5000 FPS anyone?

Yeah, my big question is what happens to the bullet? Doesn't the rotational speed of the bullet cause it to just rip itself apart?

How accurate is it at long ranges? It thought getting them too fast can cause problems (that I'm unfamiliar with because I've never gotten them that fast!).

Curious about those two things.

Other than that, cool! Are you using a blast sheild on your chrono?

The point!? This is snipers hide damn it, we don't need no stinking points!

Ranger, kudos on the crouch rocket, spin those tires!
 
Re: +5000 FPS anyone?

I would imagine that the barrel life is somewhat short. Interesting.

And, if we never push limits, then do we truly know what the limits are?

Re: +5000 FPS anyone?

This isn't all that surprising is it?
I was under the impression that the 220 Swift and 223 WSSM breached the 5000 fps mark with the lighter bullets a long time ago?
 
Re: +5000 FPS anyone?

I broke 5200 fps 20 years ago . Built a .17-22/250 for my dad. Only had one REALLY small problem . The bullets never made it to 100 yards if using lead core .

After one shot, it becomes a smoothbore musket (LOL).
 
Re: +5000 FPS anyone?

Bullets that fast with little BC slow down really fast. A standard 22 Dasher with 75gr-90gr bullets will do out to 1000yds on paper as to the 224 Mcdonald with bullets that small might be good for 500yd small game. Good luck.

Depends on your twist. Also if it is a solid it won't.
Something this fast won't have the issues of range under-overestimation and wind calls will be minimal. Leed on a mover will also be very small.
 
Re: +5000 FPS anyone?

It's been done before...those bullets have the BC of a ping pong ball unfortunately.
 
Re: +5000 FPS anyone?

As soon as it hits something it would disintegrate. The energy alone would be devastating wound wise.. I'd like to see it shoot ballistic gell for the hell of it, but I think it's purpose is one of entertainment more than practicality.
 
Re: +5000 FPS anyone?

That magical 5k
cool.gif


A friend & I with 22-243s managed over 5200 a few years ago, they were overloaded a little.
At just over 5000 the litle 30 MEF had little effect on bunnies, "very underwhelming" was his discription.
Late last year I got a Kimber Longmaster VT and had another try at going faster, especially as I had a decent crony than wasn't prone to exageration like some of the cheap ones.

22-24398BBarrett007.jpg


That speed was a little hot & need to be backed off, I managed another 150-200fps with most of my loads with that rifle.

It really is only good for laughs though as a 75 grain Amax or similar is much more useful beyond 3-400 yards.

I must drag it out again & have a play

Re: +5000 FPS anyone?

What about .22-250 Ackley Improved? I saw this load on another site a while back. Thought it was kinda nifty.

Bullet Berger MEF
BulletWeight 35 grs
Powder Vihtavuori N135
PowderWeight 46 grs
Primer
Brass Make Remington
Velocity 5130 fps
Group 0.929 (inches by 3 shot at 100 yds)

Energy 2041 ft-lbs
TKO 5.69
OGW 248 lbs
IPSC PF 179.55

All in all, it's cool to push limits like this. In search of knowledge and enlightenment. And 5000fps oughta enlighten a few things...
 
Re: +5000 FPS anyone?

A Steel sabot in a plastic jacket would be interesting at those speeds.

Wonder what the BC of the little arrows are?

Heh, does it seem odd that he put a lot of effort into the custom wildcat cartridge and chambering, shelled out for a Nightforce BR scope, and then kept the plastic SPS stock?

Never shot 35 grainers in my AI, but I know you will never hit that with 40 grainers
 
Re: +5000 FPS anyone?

My 22 cheetah pushed 40 Noslers at 4300FPS rather easy.
Loaded 40 nosler in my factory 223wssm just to see how it would do and hit 4450Fps. Fun on Prairie Dogs but toasted the barrel rather quick.
 
Re: +5000 FPS anyone?

I hit 4403fps(nine shot avg) with my 22-250 before. 40 grain blitz kings and 39.5 grains of XBR in Lapua brass with BR2's. To much pressure tho so I have went back to 39.5 of Varget for now with 4177fps avg
 
Re: +5000 FPS anyone?

Wow.. that's amazing. What range were you getting with that sucker?

Bet if you had some solid brass bullets this would kick some ass (and your bank account).
