2026 MEME THREAD: Accuracy Coincidental. Taste Questionable. Therapy Recommended.

^ ^ ^ Problems there are several

.50 BMG brass is .804" dia - 12 ga shotshell's brass is .800"

12 ga chamber is either 2.75" or 3.00" in length whereas the .50 BMG is 3.91"

Even if one could close the bolt on the case, then that's where the real danger lies: 12 ga chamber pressures are in the neighborhood of 11,500 to 14,000 psi but not designed to contain the 55,000 to 65,000 psi pressures of the BMG cartridge.
