50 BMG necked-down to shoot a stay pin. You load the powder through the flash hole as the neck is too narrow. It's an old gag article from the Handloader magazine about 30 years ago.

You're brave using a suppressor. The US army concluded in .50bmg necked down to .22 tests that the M193 projectile comes apart shreading it's jacket at roughly 6000 FPS due to the rotational force.

There is a good chance that the 6” group was because of the use of a Sabot through a suppressor... not a good idea for safety reasons, accuracy reasons, and equipment damage reasons btw.

It's only that fast near the muzzel, the low BC of the small bullet causes it to decelerate rapidly. A little .223 from this isnt even supersonic at 400 yards. Whereas a 200g high BC (above .7) bullet going about 3000 fps is supersonic out to 2300 yards more or less. In reality this Sabot round wont even make it to a mile.

It’d probably be the best way to try and boost muzzle velocity, if it actually worked (some explosives are more insensitive than others).

Glen: hey it's on the paper Me: see nothing

@5000 fps, you should try to get a 1/2" armour plate to shoot, there's a slight chance to go through.

Holy shit! My ears are almost ringing on my headphones hahaha!

I wonder if sending sabots down the pipe that fast just strips the rifling out of the sabot. Meaning when the sabot/bullet leave the barrel at only a fraction of the barrel's twist rate. Plastic can only grip the rifling so hard.

It isn't a 223 bullet but is a 22 cal bullet that can be used in a 223 or any other 22 caliber cartridge. It is called a Sabot and years ago they were made for several different calibers. 30-06, 308 and several others I believe, I still have some for a 30-06, in my rifle they shot about a 2" group at 100 yards and had an advertised velocity of around 4000 FPS.

Sheesh! Mine flies at 3100 fps and blew right through two deer this past Saturday. (An exit of one was through right shoulder) Couldn’t imagine this kind of velocity. Ps: both deer didn’t run more than 10 yards before dying. 300 may be overkill for deer, but I like knowing the animal dies quickly even if you land a shot mid mass.

For better accuracy you might try them without the suppressor. Which powder?

I picked up a MPA Ultra Lite .300WM today. I took it home and put a couple rounds through it in the backyard. My mom comes running out of the house thinking our gas tank had blown up...lel.

Also a breakopen single shot weapon may also prove helpful.

Plastics of the sabo probably weren’t surviving the pressure. So with that in mind the bullet was just bouncing around. The pressure provided by the bullet was not enough which probably left some un burnt powder. You may get high speed but unless it’s with a proper shouldered and crimped case with the right amount of powder you’ll never get the the round to function properly.

Looking at this vid and your shooting, it confirms that my rounds were definitely off or I am a shite shot.

Very good!

Sabots DO NOT peel away from the projectile at the muzzle because the air in front of the bullet is being forced to travel at the same speed. A short distance from the muzzle, that changes and resistance from non moving air peels off the sabot. I know I didn’t use the correct scientific words but.....you get my drift...right ? Super high speed film confirms it.

Are your sabot's custom machine cut or simply molded?? And are they fairly soft or slightly hard?? You may just want to delve into this as well for flight stability. But I'm most certainly not trying to tell you how to do this monumental task and you've definitely picked a doosy young man 👨!!! Again I wish you all the luck in the intier world sweetheart!!!

The assassin bullet.

I wish someone would neck a 50 g down to .22” or .172”. If he can get 5,000 FPS I bet with the right powder (and only solid brass bullets) they could achieve Mach 5. Maybe even start hitting the 6,000 FPS. I do wish he could test these loads with a lab radar or something anything a bit more reliable than a chronograph. There’s too many wired ways that could be off. Jacketed billets can’t really survive past 4200 FPS from what I’ve heard. I bet those bullet weren’t in good shape. I wish he had captured one in some sort of soft medium!!!

Brassfetcher.com has many ballistics gel tests, and I remember seeing one of the saboted rounds that was quite impressive.

would of thought that speed with the spin rate would tear those projectiles apart

I think they were called nitro accelerators if I remember right and coyotes really hate them, LoL

Most of the issues with hyper velocity sabot rounds come from inadequate rifling as .22 rounds are not meant to be fired out of a barrel optimized for longer .30 caliber projectiles as many 30 cal rifles are offered in a 1 to 12 twist rate. HOWEVER: Most 30 caliber rifles such those in the 30-06 are now also offered in 1 in 10 twist rate nowadays which is closer to the optimal 1 in 9 twist rate for 62 grain rounds like MK-318 and M855A1. While Accuracy is not guaranteed to be as good as a normal longer 30 caliber bullet (Around 2.8-3.5 MOA depending on how the round was loaded which frankly is more than good enough for most varmints save for the smallest ones) it is acceptable for the velocity the bullets are going, as the faster bullets travel the less effective spin becomes at stabilizing the round without a corresponding increase in Length to diameter ratio. However, I do have an interesting proposition. Instead of .223 rounds why not load 5.45 russian rounds (Actual diameter 5.6mm)? An 80 grain round for the caliber exists and it is a longer bullet, and the optimal twist rate is also 1 in 10. This gives it the perfect combination theoretically for: -A high muzzle velocity in excess of 4800 feet/sec and likely in the ballpark of 5000+ with 300WM cases -A stable projectile with the optimal length to diameter ratio that has a twist rate that matches those of most 30 caliber bullets -Good energy retention as that 80 grain round is rather heavy for its caliber. -Accuracy as a fast and stable round = less drift and drop. To give you an idea of how accurate the 80 grain 5.45 7U1 projectiles were, they achieved a 1.04 inch R50 group at 100 meters, or roughly a 2 inch group in American standards. This gives it a mechanical accuracy of 2 MOA.

Talks like Josh over at RLM when he is in front of a camera... He is honest though; most would edit out such mistakes.

Shouldn’t shoot a sabot through a suppressor!!!!!!!!!

Not a chance in hell I would have pulled the trigger on that rifle. Lol. Maybe with a string from 40 yards away hiding behind a tree.

I found a box of these for 30.06 haven't tried them, but they would make a hell of a coyote round.

You might have had chunks of sabot in your suppressor baffles after that

The absolute mad /k/ommando

would love to see a 6.5 creedmoor projectile from a 300 win mag

That would be close to, but a bit smaller than a 6.5-300wby which is already a factory chambering lol. Also 26 nosler which is 404 Jeffrey necked down to 6.5

Old News. I was getting 4500-5500 FPS out of .223\.30/06 back in the '70's. Then the ATF had a brainfart and killed the fun in the '80's. I wonder if the sabots could be 3d printed........

How long is the barrel going to last

Probably longer than standard 300wm

the sabots are not coming off before it hits the paper. The holes in the target look much to big to be .224 cal.

I haven't used .30 cal sabots much.... loaded them in .300 Savage, .300WM.... had good luck with .45 sabot with .38 bullet, out of .410 smooth bore...reasonable accuracy..... reportedly, accuracy with .30 sabots not good enough for varmint hunting. I would be interested in velocity / accuracy for short-range, such as 7.62 X 25 Tokarov pistol & sub-gun....

I remember 308, 30 30,an 06 thirty years ago,nothing new, but another idea.

Question is how quick is the barrel going to burn out.

Very quickly. I personally doubt it'll last more than 500 or so shots. Putting my numbers into 'Mike's barrel life spreadsheet' from accurateshooter.com gives me a barrel life of 950 rounds or so.

It's not the bullet velocity that burns out the barrel, but extreme pressure needed to get the standard weight bullet up to Extreme Velocity and that causes extreme heat. There's a reason why they call it "burning out" a barrel. Too much heat at the throat acts like a blowtorch. With so light a load he doesn't need high pressure to go fast so there's no extreme heat to burn out the barrel. Ever see a 22 caliber pellet fired out of a 22 long rifle with a blank cartridge? Not a lot of pressure and not a lot of powder but those light little pellets come out screaming fast, and the barrel does not get burned out. Also the barrel doesn't get burnt out it's the throat that gets burnt out, you know that part right in front of the chamber where maximum pressure and maximum heat are generated before the bullet goes out the barrel.

Velocity problems sure but I doubt he has high pressure problems. Would have to look at his brass, but those .223's get moving pretty quick unlike a 30 cal. mitigating chamber pressure significantly.

WOW oh WOW that's extreme to say the least!!!!

Yeah she's trucken along there 🤔

used to be a round called xcellerator or something like that from i believe remington that was a subscriber sabot
