Is 9mm really a better round than .30 carbine?
I'd rate it between .357mag and .44mag, and above 9mm 40s&w and 45acp.
There are two self defense loads in .30 carbine
.30 Gold Dot 100gr 1990fps 219pf
.30 DPX 110gr 2025fps 202pf
or a standard load
.30 Winchester 110gr 1790fps 196pf
Here are some defensive and hunting loads in 357mag
357 DPX 125gr 1300fps 162pf
357 Cor*bon 180gr 1200fps 216pf
357 Cor*bon 200gr 1150fps 230pf
compared to standard 357mag jhp
357 Winchester 110gr 1295fps 142pf
or a standard 45acp ball
45 Winchester 230gr 835fps 192pf
even a 44 magnum jsp
44m Winchester 240gr 1180fps 283pf
You can see the .30 carbine has some good power. Not 44 Magnum power, but greater than most pistol cartridges.
it also has better range:
.30 winchester 50yrds 1601fps 626 ft.lbs. energy
.44 winchester 50yrds 1081fps 623 ft.lbs. energy
Hmmmm. The .30 has more Energy (783) than the .44 (741) at the muzzle too. I wonder the relationship between energy and
power factor (pf)
