It has taken 20 years, but a group of Canadians is ecstatic about achieving new heights in ballistics. Andre Milne of Unicorn Aerospace, and his colleagues say they have designed, crafted and tested new 9mm handgun bullet that, according to test data, surpasses anything currently on the market, in terms of velocity, punch, accuracy and distance.

I have only one question, WHY?

Sorry, I just don't get it when someone goes this far to get a PISTOL round to accurately hit a target at 100 METERS. I'd just invest my time and money in a rifle.

Presumably, though, the aerodynamic design can be extrapolated to rifle rounds. 9-mm is ostensibly more challenging because there are fewer form factors to play with. It sounds like they made a pretty significant advancement over the conventional nose and tail designs.

That's my thoughts, and maybe the technology can be used for rifles, too.

Awfully short on actual evidence, I'll put it on the shelf with cold fusion until I see more proof.

"Awfully short on actual evidence"

ya... no paper or ballistic info... I thought it was neat... as velocity goes up so does the recoil, etc. 20 yards is about my limit with a pistol or revolver... with a good benchrest rifle, at 100, I used to be able to put 10 shots on a dime... (0.3 minute).

There is a maximum pressure allowed for each cartridge, there is no way the aerodynamics increased the muzzle velocity so all that increase has to come from a lower mass projectile. Again, I'll wait for real data.

concur...

There are possibly some things one can do with the obdurating band and its friction. The typical copper jacket deforms to conform with the barrel, which possibly sucks up some of the KE of the round.

Reduced friction?
That would mean less energy lost heating the barrel by friction and more energy available for acceleration.
A higher muzzle speed should help with ballistics with almost any shape bullet.

maybe teflon... a high temperature lubricant? a progressive powder?... dunno there was little info... and, I had assumed the material was classified, not snakeoil... and with the greater velocity, comes a greater recoil.

Sabot discard? Seems to work on big stuff.

The use of discarding sabot was generally to allow a non-conventionally-shaped projectile, like those designed to be more effective in piercing armor, to be fired from a system designed for conventionally-shaped projectiles. I'm not sure that it can in any way be used to give a projectile a higher muzzle velocity than any other conventionally-shaped projectile would have had, all else being equal.

It does allow for a lighter projectile to be fired from the same bore of tube - lower mass implying higher velocity for the same imparted energy.

Chieftan tank armour piercing round mv of 4,494f/s. Pretty quick. Goes through 355mm armour plate.

We can compare numbers:

M456 HEAT
Projectile weight 10.3 kg
Muzzle velocity 1176 m/s

M735 APFSDS -- DS = discarding sabot
Projectile weight 3.8 kg
Muzzle velocity 1501 m/s

M1 HE
Projectile weight 15.0 kg
Muzzle velocity 498 m/s
