Here is a concise summary of the provided text:
**Title:** Muzzle Blast Experiment (Kentucky Ballistics)
**Objective:** Test the lethality of muzzle blast from various firearms on a ballistic dummy head.
**Firearms Used (in order):**
1. **Smith & Wesson 460 Magnum (Handgun)**: Caused minor burns, non-lethal.
2. **CMMG Resolute (Rifle, 350 Legend)**: Minimal effect, non-lethal.
3. **Savage 111 (Rifle, 338 Lapua)**: Caused a cracked skull, considered lethal.
4. **Barrett 50 cal (Rifle, 50 BMG)**:
* Tested with a dummy head at a distance: Minimal new damage.
* Tested with a strapped-on hand: Severely shredded the hand.
* Tested with the dummy head against the muzzle brake: **Extremely destructive, 100% lethal**, with widespread debris.
**Conclusion:** The experiment demonstrates the increasing lethality of muzzle blast with larger caliber firearms, with the 50 BMG producing catastrophic results.
Here are the key facts extracted from the text, each with a number and in short sentences:
**Firearms and Equipment**
1. The host, Scott, is testing muzzle blast effects on a ballistic dummy head.
2. The channel is called "Kentucky Ballistics".
3. The first firearm tested is a Smith & Wesson 460 Magnum with a 14-inch barrel and muzzle brake.
4. The second firearm tested is a CMMG Resolute chambered in 350 Legend with a muzzle brake.
5. The third firearm tested is a Savage 111 chambered in 338 Lapua with a muzzle brake.
6. The fourth firearm tested is a Barrett 50 cal with a large muzzle brake.
7. Ammunition used includes Underwood Ammo (250 grain extreme penetrator), 350 Legend, 338 Lapua (285 grain), and 50 BMG (660 grain Full Metal Jacket).
**Test Results**
8. The Smith & Wesson 460 Magnum caused minor burns on the dummy head's face.
9. The CMMG Resolute (350 Legend) caused slightly more burn on the dummy head's upper lip.
10. The Savage 111 (338 Lapua) potentially cracked the dummy head's skull, with the skin still intact.
11. The Barrett 50 cal (660 grain FMJ) caused significant damage when fired near the dummy head.
12. When a hand was attached to the Barrett 50 cal's muzzle brake, the blast broke the thumb and severely damaged the hand.
13. Firing the Barrett 50 cal with the dummy head close to the muzzle brake caused extreme damage, including bone fragments and tissue spray.
**Miscellaneous**
14. The Vulcan Weather Lock bag (sponsored by Vulcan Arms) has an IPX6 rating, meaning it's resistant to dust, dirt, mud, and high-pressure water jets.
15. The host took safety precautions when firing the Barrett 50 cal, including using a cinder block, lead bags, and a remote trigger.
