It depends on what you mean by bigger, but the answer to the question you're probably asking is yes. A .45 caliber bullet is .45 of an inch in diameter. A .44 caliber is .44 of an inch, so it's slightly smaller in diameter. However, .44 caliber bullets are many times longer and heavier. A common weight for .45s is 200 or 220 grain, and for .44s it's usually 240 grains.
A 44 magnum is just the new and improved version of the 44 special which the special is a 44 caliber. Magnum just means bigger so the 44 magnum is pretty much in between 44 and 45 cal. However, if you mean size, .45 is slightly larger in diamater than .44.
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.
No. The AK-47 fires the 7.62x39mm round, which is of the .30 caliber, smaller than the .45 caliber.
Depends on which 45 and which 44 chambering you are talking about the load
the N frame is usually the bigger caliber as with 45, 44 and 357...........
The .45 caliber is bigger in diameter. If you mean weight. The .45 caliber is generally heavier. However there are some lightweight .45 caliber bullets that are lighter than .357 caliber bullets. Generally speaking .45 caliber bullets weigh between 180 - 230 grains. While .357 caliber bullets generally weigh between 158 - 180 grains. If you are talking about diameter, the .357 caliber bullets are approximately 0.357 inches in diameter. The .45 caliber is approximately 0.450 inches in diameter. Again, using this measure, the .45 caliber is the larger bullet.
It depends on the load
No.
A 40mm handgun would fire a bullet the size of a golf ball. No such critter. There IS a .40 caliber handgun (about 10mm). There are dozens of larger caliber handguns than .40 caliber. They include the .41, .44. .45, .455. .460, .475, .500- and several others.
The longer case of the .44 Magnum holds more powder, and, even though the .44 is smaller in diameter, it tends to pack a heavier projectile, ranging from 240 to 350 grains, vs. the typical 165 to 235 grain projectiles used by the .45 ACP.
No. There was a 45
Either platform can be larger than the other. The 45 has the larger projectile. Caliber is defined as the diameter in fractions of an inch, so .40 caliber is smaller in diameter than .45 caliber. Caliber can also be defined in the metric system, measured in milimeters. The .40 caliber cartridge is equivalent to 10mm in diameter. As noted, the size of a handgun can vary widely within one caliber, so it is perfectly reasonable to have a smaller handgun crafted in a larger caliber.
