The one with the bullet passing through the beer can reminds me of a past discussion regarding changing US military rifle ammunition from 7.62mm (.30 caliber) to 5.56mm (.223).

One demonstration involved, of all things, a tomato can. The 7.62mm round struck a tomato can, punched an entry hole that was about the diameter of the bullet, and made an exit hole larger than the entry. When the 5.56mm round struck a similar tomato can, the energy of the bullet was mostly "spent" within the can itself, meaning that it blew out the back of it. The .30-06 cartridge that was used in WW I & II for the M1, and the development of the .308 (I believed designated as 7.62mm NATO), gave way to the 5.56mm NATO cartridge, dubbed by some as a "hot .22," which even the Kalishnikov rifles eventually adopted.
