One must define power in this case. The .45 transfers more energy to the target, is bigger, and can cause more damage. Overall, the .45 is more powerful. The .38spl and the .45 travel at close to the same velocity (depending on the powder load, projectile and firearm), yet the .45 is a ton heavier (up to 100gr heavier), that's a lot of energy imparted to the target. So, I would say the .45.
it is a little less powerful but not by much
.38 Special is a specific caliber. There are other .38 caliber cartridges- about a dozen. The most common OTHER 38 is the .38 S&W, which is shorter, fatter, and less powerful than the .38 Special. MOST of the different .38s do NOT interchange.
38 is the size. This answer is actually correct, but more specifically, .38 special (and many of the other .38 caliber cartridges) are actually .357. The caliber ".38" was chosen to distinguish between .357 magnum and .38 special.
The .357 Magnum cartridge is longer and much more powerful than the .38 Special. While .38 Special ammo CAN be safely fired in a .357 Magnum, the reverse is not true. It is dangerous to try this.
In general, a .38 Special +P+ load can be more powerful than a mild .380.
No. <><><> Above is correct- however, ,38 Special CARTRIDGES can be used in a .357 magnum revolver. The .38 Special is actually not .38 caliber, but .357 caliber. .38 caliber bullets, such as used in the .38 S&W catridge, cannot be used.
Yes If it is .38 special, this is correct. There are other types of .38 caliber other than .38 special, however.
The term ".38 Special CTG" is an abbreviated way of saying .38 Special Cartridge. It is the caliber marking for a revolver that fires that cartridge. While it is NOW the most common .38 caliber cartridge, there are more than a dozen DIFFERENT .38 revolver catridges that were made at one time.
.357, considerably.
.38 Special, yes. Other .38 cartridges (such as the .38 Long Colt or .38 Super), no.
