+1 to James_wingthwong_Banks, it would be very interesting to look at the projectile in flight with a high speed camera, this would answer the question about what the sabot and projectile is actually doing, with the 300WM and a projectile of the weight being used the velocity should be much higher, some time ago I experimented with some loads in my 300WSM and had a 130gn .308 projectile running at 3750 fps, so you should be able to get a 55 or 62 gn projectile going well over 4000 fps, as long as the sabot can hold the gas.

i would bet money this has to do with load density. .300 WM can shoot some long and heavy projectiles, and has case capacity aplenty. These .22 caliber bullets aren't going to come close to pushing the max OAL, and its safe to assume these were loaded from published data, meaning reasonable charge weights. The real tip off was when the lighter bullets came in at a lower velocity. Assuming they were loaded to the same OAL, the cartridge with the lighter bullet would have a lower load density (takes up less space in the case) and therefore a lower pMax. Id bet switching to a fluffier powder or seating the bullets deeper, if possible, would give you much better velocities

WHOA

Interesting rounds. I feel like the brass and bullets would have been better off in/with their intended cases and projectiles. But it was still worth it to test out.

there could be a couple reasons why you're not getting optimal velocities 1) this is the most likely, the sabot shell is letting more gas than normal to go past the bullet 2) because the bullets are so light they accelerating fast enough that you're not getting max pressure by the time it leaves the barrel, a longer barrel would remedy that. 3) the sabot shell has enough friction reduction compared to copper that you're getting essential the same issue as #2. the last option is a combination of all 3.

The problem with sabot is that the standard powder load for the cartridge isn't filled with the correct burn-type powder. Its like low-mass shotgun rounds being ejected mainly by the primer charge.

As always your videos are always great.

Like Bruce below says, I think the sabot isn't sealing properly going down barrel

I read somewhere that, copper fouling causes issues with sabots along with a bad crown. I'd scrub the bore with copper solvent before you fire sabots. Do a break in procedure scrubbing the bore with copper solvent in between shots. Then do a final scrub after you do your cleaning and break in regiment. I'd also have a gunsmith inspect the crown. The sabots probably are not sealing properly to the bore. It is possible that the sabots are melting to the bullet. To varify that I'd shoot them at a paper target. If you have .308 holes as opposed to .224 holes the sabot jacket has melted to the projectile.

Maybe the sabot is too thin where it contacts the base of the bullet, resulting in the sabot being burned through. I'd even go so far as to wonder that the material the sabot is made from is too soft and shreds when it hits the rifling. A lot of variables.... High speed camera would let you see what's going on.

My bad, forgot to clarify that I didn't mean the sabot but regular bullets. Also maybe I should ask a novice question but I thought most of the motivation of a sabot was to give the mechanical work of a large bore to a small-bore round but maybe that's not the real reason why tanks use sabots but that Mach 6 would destroy the barrel if metal-on-metal?

I love sabo rounds ,especially for 308 / 223 combo, a great zinger.

What’s the muzzle speed of the lightest factory load? I get 3175fps on my 7MRM a165grain Sierra GK BT...and that’s a soft load... How’s the accuracy??? I wonder if the sabots are effected by powder burn & barrel heat...I never had luck with the .308 “Accelerators”

I can’t understand how the projectile doesn’t bounce down the barrel or not ?? Plus I think the sabot would act like a parachute as it goes down range before falling away ??

Got some of these for my 30-30. I wonder what kind of plastic the sabot is made of? Sabots are not legal ammunition where I live, so I have no clue wherever they are injection molded or 3D printed. If printed, my guess is that the plastic is powderized in the barrel due to the pressure.

Love the videos as always. Those numbers are very low, like i've said before, i push a 110 grains V-max up around 3300 fps out of a 308 Win.

with the 75 gr 556 bullet in the 300 wm what would be the max effective range

Good testing....Good stuff....

Loading for HK polygonal barely found that neck crimp was required. Less resistance was preventing pressure rise before bullet left the case. They left barrel before powder finished burning.

I have a bag of about 500 of these "remington accelerator" sabot's that I have reloaded in a lot of different .30 cal rifles but not the .300 wm as of yet.. My experience have been that they like to key hole at ranges over 50 yards unless you're using a rifle with 1:10 or tighter rate of twist... You really have to put a fast spin on them so they stabilize properly.. Try them on an organic target like a watermelon.. Its pretty impressive.. 😀👍

Usually at this caliber a round already necked down to burn more powder from the get go was proven way faster than a sabot mod. Easier to get the bullet to accelerate on its own through rifling with a better gas seal against the barrel. A tank Cannon is different since that high speed fin stabilized sabot is gas sealed against a smooth bore or some specialty rifling. The only good use for a sabot is for a rifled shotgun when hunting big game beyond shotgun slug distance.

I'm thinking the sabot isn't holding the pressure like a full-size bullet would and you're getting pressure blowing by it

Interesting guys I was not aware the components were available to load Sabots thats cool. My Dad was a big fan of the 3006 Accelerators when they came out they were like your loading a .30 cal with a .22 in a sabot those were clocked 4020 fps and you guys have a lot more case capacity than an 06, I think you need to look hard at some burn rates of different powders along with some barrel length changes? If you use the 3006 Accelerator as you baseline with what your using as components I would think you should be in the mid to high 4000 FPS range. I think your going to find the biggest variable is going to burn rates of the powders your using, with the case capacity you have the slower the powder burn rate will keep your pressures in check but then your barrel length is going to play a big part in this also. At 4020 fps the bullet was spinning over 100,000 RPM when it left the barrel and Remington said the sabot was shed from the bullet within 12 ft from the muzzle. I could see this being pretty cool experiment but its going to take a whole lot of time to get the optimum loading to make this work effectively enough to make it worth it guys?

Sounds like a great caliber

My next question would be can you try longer barrel lengths? 26 inches with a 300wmg I think would provide a more complete powder burn. Maybe try shooting at night to compare muzzle flash.

Nice video. Shows i will stick with normal loads. Wonder what that sabot did to your rifling? My. Ruger mark 2 heavy barrel .223 shoots ultramax 44gr nosler ballistic tip at 3650 mv I was impressed with its velocity. Fastest bullet i have out of all of my weapons

What does it do to an old tire and rim at 100 yrds?

@WHOTEEWHO

Have to see

What if the bullet is tumbling because it's going down the barrel too fast for the sabot to engage the rifling in any meaningful way? Also likely the reduced bullet mass is reducing bullet's time in the barrel below the threshold needed to burn the powder, creating a "terminal muzzle velocity" for the given barrel length.

Well, this explains why ive never heard of these before.

Is that your range setup? Or heavy metal’s?

Let's see if you got the sabots Right there. Yes you need to get the sabot out of the way. The way they sit and gas check matters. Sabot quality is a huge factor too.

Couple issues, the fireball tells me the powder is burning to slow. Could be the sabot leaking but try a faster burn rate powder. Most likely the sabot disintegrate from heat and pressure though. Make a sabot from copper or brass and bet it gets close to the "eargasplitten loudenboomer" look that up, it's a real thing!

Along with faster powders, you can also drill out the flash hole just a hair bigger to her a better ignition.

Seeing some mistakes here. Years ago I bought a bag of empty accelerator sabots from the Shotgun News. Tried to find loading data for a .308 Win for 55 grainers and for some tungsten that I had turned to .224, with mixed results and success. A co-worker had a friend that worked at Blount, which at the time was the parent company for CCI/Speer/IMR. He worked on loading data. His recommendations to me- you MUST use heavy crimp, otherwise the sabot displaces before you get a burn established. Then the best part was this "fill a case to the neck/shoulder line with IMR-4198, seat, crimp hard, and let her rip"..... he claimed that the burn rate in that size tube, with a sabot and not a bullet could NOT overpressure the gun. I AM NOT saying to try that here, BUT it at least gives you an idea that burn rate matters with a sabot. For the .300 look at IMR 3031 or WW 748.

Just left comment on previous video saying that!!! Lol!! Felt dumb but glad to know I wasn't alone in my thinking!!!

Slow motion footage at the end of the muzzle. I bet the sabot is exiting the barrel before the bullet from getting pushed past it inside the barrel. If a stronger sabot material was used the speeds would probably be even faster if that is what is happening and I believe that to be the case if the reading seriously dropped by 500 feet per second from the muzzle to 100 yards. Either way it would be interesting to see.

Great video you and Paul y’all be safe and GOD BLESS

I wonder if the sabot is being pushed through the bullet because of the pressure

15gr bullet in a 17remington,in the hogdon manual is a little over 4800

The charts tell me that 22 swift goes over 4000fps

It still holds the world record.....since 1935. It's all I use for bench rest and varmint shooting.
