12 gauge vs 20 gauge Penetration Test with 7 1/2 shot - TheFireArmGuy
This test compares the penetration of 12 gauge and 20 gauge shotguns using Federal 7 1/2 shot at various distances. Both gauges effectively penetrate targets at 10 and 20 yards. At 25 and 30 yards, the 12 gauge shows a larger spread and more power. By 50 yards, the 20 gauge pellets begin to fail penetration, while the 12 gauge still achieves it, indicating 50 yards is the practical limit for reliable penetration with this load.
