00 Buck or 32 ACP ?

[Rodolfo Fierro]

What would have more effect, nine 00 pellets from a 12 ga. or nine shots from a 32 auto ?

[Connal]

At what range? Centermass? Appendage?

The problem here is, you are comparing, not only apples to oranges. But apples from mars, to oranges from mercury.

Each has it's own merit, in varying situations. However, comparing a handgun round, to a shotgun round. You might as well be asking what is more effective, a hat, or a pair of shoes.

Effect of what kind? Ballistic damage? Conceal ability? Price efficiency?

Myself, I wouldn't want hit with either of them.

The delivery vehicle for (9) simultaneous .32 ACP doesn't exist.

I was thinking of the distance of 5 yd at center mass. Comparing nine 32 Auto shots to one shot of 12 ga 00 Buck. What would the difference be?

[Pete D.]

The 12 gauge will shoot all of its .32 caliber pellets at about 1300 fps. The typical .32 Automatic with a two or three inch barrel will shoot its bullets at about 800-900 fps.
The power difference is substantial especially given the fact that all the pellets from the SG arrive within milliseconds of each other.

So the 00 Buck have about a 50 % velocity advantage, and arrive at the same time, causing more shock.

[Rodolfo Fierro]

Does the 50% increase in velocity translate to 50% more penetration?

Yes.
Try putting the 12 ga in your back pocket.

About penetration - I don't know. Maybe some one else does.

So much for firepower; it didn't fit.

Every time you double the velocity of a given projectile, you quadruple the kinetic energy - which any person with even just a 1st grade education could tell you it will penetrate further.


A single #0 buck .32cal ball weighs about 49grains.
@1300fps each ball has about 183ftlbs of energy.

The .32acp follows up with:
65gr bullet @ 925fps = 123ftlbs of energy
71gr bullet @ 900fps = 127ftlbs of energy.

Now all three above have about the same momentum(within a range of 2 between all three figures above), but the much higher kinetic energy of the #0 buck ball will help it penetrate further.
