” In the civilian market, yellow-tipped .50 BMG rounds are frequently Dominican Republic-made armor-piercing (AP) ammo. This specific lot has a nasty reputation for being hot-loaded, having degraded powder, and causing damage to rifles due to dimensions being on the large side. “
That’s what happened to Scott of Kentucky Ballistics on YouTube. He got a hot-load .50 BMG and part of the gun tore his neck open due to rupturing under pressure. He only survived because he plugged the hole with his thumb.
His tagline is, “Stick a thumb in it” along with, “She be kickin’!”
