Interesting to see the yaw in the projectiles.

Thanks for posting that!

Best job I ever had!
That said an APFSDS round looks a little different leaving the gun.
When I was in the USMC, a Gunner told me that the yaw on the M855 from a 20" M16 meant that it had the best penetration at 200 yards as that was the soonest it yawed the least.
Fun to see the concept in high speed video.

What is demonstrated by the yaw is one of the reasons Most modern tank guns are smooth bore. Both HEAT and APFSDS Are adversely affected by spinning and yaw. The dart of a sabot round relies on all its mass being behind it when it impacts armor. If it is yawing it’s penetrative properties are greatly diminished which is the point of Kontakt reactive armor as well as the wedge armor of modern Leopard tanks.
The first shot in this video shows the lack of yaw from a APFSDS round although it has been fired from a rifled barrel (pretty sure 105mm L7). The second shot is the canister round from the 120mm M1A1 gun.
