These videos were filmed quite a long time ago and have been on the internet for years. They came to my attention when I was researching the strength of the Blaser actions.

For those wondering, filmed at 4000FPS. Barrels completely plugged. Caliber 308. Bullet weight 168 grains.
The rifles, shown in order, are made by:
