The Cybertruck failed a YouTuber's bulletproof test when shot by bigger guns

• YouTuber JerryRigEverything put Elon Musk's claims that the Cybertruck is bulletproof to the test.

• The truck could withstand shots from a handgun, but couldn't fend off faster weapons.

• Musk has said that "energy per unit area" is what matters when it comes to bulletproof tests.

If you pack enough heat, Tesla's Cybertruck isn't bulletproof.

Zack Nelson, known for his YouTube channel JerryRigEverything, put the electric truck's stainless steel exterior to the test. In a video that was uploaded on Friday, Nelson shot the vehicle with a series of guns, including an AR-15 and .50-caliber rifle.

"Nothing is actually bulletproof. There's always going to be a bigger bullet, but today we are going to see scientifically where that line gets drawn," Nelson said in the video.

The Cybertruck was able to survive shots from a 9 mm handgun — which Musk had previously said the vehicle could withstand — and a .22-caliber rifle, which left small dents in the metal. However, Nelson noted the truck's metal cracked if the shots landed too close together on the metal.

The truck took on more damage, however, when Nelson brought in some faster weapons, including a .17-caliber rifle, as well as an AR-15 and .50-caliber gun. The video from the .50-caliber gun shows the shot flying through the car door — which Nelson left open to avoid damaging the truck's interior — and taking a nickel-sized chunk out of the metal. The metal also cracked all the way through when Nelson fired the .223-caliber AR-15 at the vehicle.

While the truck didn't prove entirely bulletproof, Nelson said he was still impressed by its durability.

"The truck is still in one piece," Nelson said in the video. "There's a few ventilation holes now, but, overall, I am very satisfied with how bullet -resistant the Cybertruck is. It works on 9 millimeter, .22. Anything faster than that and there's gonna be a hole, but still slowing down a bullet is infinitely better than letting it pass through both sides of the vehicle."
