"Worked well in the close in combat of the jungle"

A 115gr 9mm bullet is .355in and, depending on the barrel length travels at 950-1150fps.

00 Buckshot is .33in. My Federal 3inch mags have 15 of those pellets and they travel at 1200fps.

Do the math.

When shooting my Mossberg 509s with those 3in mags, it kicks like a mule. Twice that of my ought 6.

Out to 75-100ft the 12 gauge shotgun is the most powerful and effective small arm on the planet. The Marines still use the 509s and credit it to the effective clearing of Falluja, Iraq.

First time I fired a 12 Gauge with slugs I thought my shoulder would fall off

However when deer hunting I never even felt the recoil
