.30 vs .355
.30 vs. .355
The .40 is a larger diameter round. The projectile has a dimension of .4005, versus the 9mm Parabellum, which has a dimension of .356. Of the two, the .40 is the more powerful cartridge.
It's the same. The caliber of a bullet is its diameter.
less power vs more power all else being equal.
.355 vs .40
Of course a 45 is more powerful, but the 9mm has the advantage of speed and a larger chamber. If you only get one shot, pick 44. Multipule. Then pick 9mm
No. This is a .22 caliber vs .243 caliber (.243 being a 6mm).
9mm (usually called 9mm Luger or 9mm Parabellum) almost always has a higher muzzle velocity than the 380 ACP (also called the 9mm short, 9mm Kurtz, and 9mm Corto). The two bullets are essentially the same diameter however the 9mm Parabellum is almost always a heavier bullet than the 380 ACP with a larger powder charge and a significantly higher chamber pressure.
The question can't be answered since you didn't supply a caliber or mm measurement.
5.56 hands down.
I assume you mean .35 Remington rifle ammunition vs. standard 30-30 rifle ammo. If so then they are not the same and although they look similar they are not interchangable. I hope this answers your question.
metric vs inch measurement
