Ah yeah no, PELE rounds are these very interesting projectiles which constructed with a purposely impedance mismatched inner and outer material and very clever internal geometry so that even though they don't contain explosive fill they will hit deform and violently "detonate" usually after partially or fully penetrating an intermediate barrier.
Do these PELE rounds have better penetration then an equivalent weight/energy tungsten core projectile?
And could they be scaled down to the more 6-8mm zone?
No definitely not to either.
Even a 12.7 PELE would probably be pretty difficult which is why I was thinking the 15-17mm range and the ALP explosive fill pumped versions for the specific application I was talking about.
From what I understand there's no reason why a 15-17mm ALP COULDN'T be done and you could definitely do it at 20mm.
As far as rifle caliber projectiles go I think we're kinda stuck with tungsten/DU.
Though on the rifle round side of things there's a guy on YouTube who's about to start selling "bushing style sabots" specifically to let you load 5.56 rounds in 7.62x39 cases to get around the Russian ammo ban.
In one of his videos he was getting 3218 fps from a 50 grain VMAX 5.56 projectile using iirc a 26 grain charge of h110 pistol powder out of a bog standard SKS without serious pressure signs from the primer/primer pocket.
What's even more interesting than the velocity in this case though was that he was halving 3 shot group size versus factory 124 grain ammo.
It definitely got my attention for sure.
Assuming that these are relatively cost effective, they're pretty interesting.
The drawback is that the sabot sides separate....sending the peices flying at angles which is bad when prone shooting
He even had to cover the chrony with wood in a different video....to protect it
Still, its puzzling why his petal sabots should be more accurate than normal sabots
Define normal sabots?
Because other than the old xcelerator sabots and the various revivals of them there hasn't been much saboted ammo commercially available and the cbjtech guy hasn't shared much in the way of results.
I meant their operation method.....xxellerator and CBJ stay in one peice. This guy has petal sabots which may be a safety hazard

Are you referring back to this thread about sabotted 7.62x39 ammo? - http://forums.delphiforums.com/autogun/messages/7943/1 (Note: This post has has been repeated in that thread)
Yes, discarded sabots flying downrange have always been a problem. They may still be a danger to current troops wearing full combat protection. We only have the word of the fellow in the video that he has managed to come up with a much more accurate design. His loaded ammo looks pretty much like the typical 7.62-to-5.56 sabot load, since the most widely available sabots have "petals" that extend beyond the case. E. Arthur Brown Company (EABCO) has been selling this sabot, for example, for over 20 years:
Sweden once had a saboted sniper round that was sufficiently accurate for them. IIRC, it was made by Winchester with a 4.81mm tungsten penetrator.

The only reason why discarded sabots are not considered a major issue with tanks is that in general, it is a very bad idea to be in front of a tank gun anyway.
That is a monster vehicle
That is a monster vehicle
Eh, for the US side yes.
The Russians though have built some really beastly (and cool looking) vehicles.
The BMPT-72 'Terminator' is basically out of the Terminator franchise; dual 30mm cannons + 4x missiles + reportedly 2x 30mm AGL's....
And then the T15 Armata with 57mm cannon looks like a land battleship, the 57mm shell is supposedly ~2x the weight of the 50mm.
