This video compares the ballistic performance of 6.5 Grendel and 7.62x39mm ammunition using 123gr Hornady SST bullets fired into ballistic chickens (simulating ballistic gelatin). Both firearms, an AR-15 in 6.5 Grendel and an AK-47 in 7.62x39mm, had 16-inch barrels. The 6.5 Grendel demonstrated deeper penetration (approximately 9 inches) and better bullet retention, while the 7.62x39mm showed more extensive fragmentation and less penetration (approximately 3.5-4 inches) at close range.

Quick Summary

Comparing 6.5 Grendel and 7.62x39mm with 123gr Hornady SST bullets from 16-inch barrels, the 6.5 Grendel achieved deeper penetration (approx. 9 inches) and better bullet integrity. The 7.62x39mm penetrated less (approx. 3.5-4 inches) but showed more fragmentation.
