Home defense: 15 rounds of 9mm or 10 rounds of .45acp?

As for penetration, that's really a by-product of sectional density and momentum. Expansion is the measure of the bullet, and nothing more. So these really should not factor into the formula when looking at which caliber has more potential.

locosway,
I really think your new formula would be more useful if you incorporated the bullet type as well as caliber. I for one am interested in comparing commercially available ammo for use as home defense against people not just a comparison of calibers themself.

For example, I would like to be able to compare extremeshock ammo in this link to more conventional stuff:

Different types of bullets (FMJ, HP, frangible, sabot, etc.) react differently depending on their velocity, caliber and what type of target they hit.

Keep us posted once you've done some testing to confirm your numbers.

I definitely would like to expand my current formula. In order to add bullet types I'd need a way to quantify their performance in some number format. Then, there's different manufacturers on top of that. Perhaps there's an easy way, but I don't know what it is right now.

Agreed,
for me - it is my Sig at distance of 15 -18 yards (more than enough for home defence).




Actually, based on our recent law – question should be:
“10 rounds of 9mm or 10 rounds of .45 in home defense handgun?”
Or even – 8 rounds of .45 (as usually it is 7 – 8 rounds for .45 handguns).

The OP has successfully rekindled the 9 vs 45 debate.
Well done, Sir!
I congratulate you, despite your evil intentions.
