When people talk of a 38, they mean .38 caliber, or 38/100th of an inch.
Likewise, a 45 is .45 caliber or 45/100th of an inch.
45 > 38 so a 45 has a larger diameter.
However, there are different lengths for each of those calibers, so a .38 Special is longer than a .45 ACP so in THAT sense, a 38 is larger (longer) than a 45.
Yes, a 45 caliber bullet is bigger than a 40 caliber bullet. A .45 is0.45 inches wide in diameter and a .40 is 0.4 inches in diameter.
Caliber refers to the diameter of a bullet. A bullet for a .38 Special is actually .357 inches across, and for a .45 auto, about .451 inches. The 45 bullet will be wider, and usually heavier. Please note that this is only the BULLET, which is the projectile. The CARTRIDGE (case, primer, powder, bullet) of the two are different size, shape, design and weight. There also is the .45 Colt bullet (often referred to as a .45 Long Colt). This is about the same diameter as the .45 auto but has a longer cartridge than the .45 auto or 38 Special.
The main difference between a 9mm and a .45 caliber bullet is the diameter. A 9mm bullet has a diameter of 9 millimeters, while a .45 caliber bullet has a diameter of .45 inches. The .45 caliber bullet is larger and generally heavier than the 9mm bullet, resulting in differences in recoil, speed, and stopping power.
Yes, 67 is bigger than 45.
Depending on the bullet, 9mm goes slower than it, but a 45-50cal.
If you mean "farther" yes, generally speaking, a .22 will travel further than a .45. The .45 is a much heavier bullet and loses velocity at a faster rate.
45 is bigger then 4.50.
Like they do today, a copper casing with a lead projectile. Some where bigger of course, a 45 round is bigger than a 38 and so on. Hope this answered your question.
The main difference between a 10mm bullet and a .45 bullet is their size and energy. A 10mm bullet is smaller in diameter compared to a .45 bullet, but it travels at higher velocities and has more energy. .45 bullets are larger, slower moving, but they have more stopping power due to their size.
First of all, 45 is not a prime number. The smallest prime bigger than 45 is 47.
No
yes, 45 ounces are bigger than 4 1/2 ounces
