9mm Spanks .38 Special? Underwood 9mm+P JHP VS .38 Special+P LHP - Short Barrel Ballistic Test

I hear a lot that the 9mm is significantly more effective and a better choice than .38 Special for ballistics. Is this true? Today I test the Underwood 9mm+P 147 gr Nosler JHP VS the Underwood .38 Special+P 158 gr LHP in a 10% Clear Ballistics gel test. Alway Specials appreciative of any channel help :) www.patreon.co...
