a laser pulse can’t shoot over the horizon or through clouds.

How hot does the tip of the projectile gets at that speed? Does it melt ( like the hornady bullet tips?) ? Does its bc then change during its travel?

Impressive concept and video. Somewhat faster than powder propelled discarding sabot rounds, but not hugely. Certainly no less muzzle blast! The cost though, is much higher, and for distant targets in the dozens of miles away, I would think they better be very large, for a first shot hit. In that laser pulses can hit supersonic missiles as if they weren’t moving, with zero human involvement, the age of throwing a more accurate rock is waning as far as leading militaries go. Just as the field events of javelin and shot put throwing of cannon balls continues long beyond use of cannons and spears, imagine the day when powder charged small arms, like bowed weapons, are used only in the “ancient” sport of rifle matches. Almost certainly outside of the 2nd Amendment, directed energy weapons won’t have a civilian role. The FAA and law enforcement can barely even contend with $4 laser pointers miscreants point at pilots.

But will it stop a Sambar deer at 100m? I hear those things are nearly bullet proof.

Guys,
I know just a little about this tech. barrel life would be fine, as it doesn’t touch it. The electromagnetic field floats down the barrel. That leave us ALL plenty of VARGET.

Glad it doesn’t use gun powder. If it did we would never see Varget or H4350.

what kind of barrel life do you get at 7800 fps?

What’s the barrel life at 7800 fps?

Wouldn’t it be cheaper, faster and better to have the projectiles orbiting around the earth until needed then diverted to the target at Mach 20?
