Your question should really be something like: "What is the difference between bullets designed for the .38 S&W Special revolvers and the .357 Magnum revolverss?? There is no difference in bullet diameter. Both are a nominal .357" diameter. But there is a big difference in composition, length, and weight; depending on the intended use. The .357 Magnum bullets must be made to withstand higher velocity, greater pressure and higher impact due to higher speeds, therefore most Magnum bullets have alloy jackets to prevent bore-leading and pre-mature disintegration upon impact. The differences are in the bullet construction, due to the speed that the bullets travel and the uses they could encounter. For target work, lead will do the job nicely, but for defense, a jacketed bullet designed to open wide, yet hold together on impact, are sometimes used in .38 S&W Special guns, as well as Magnums. I suggest a visit to your local gun shop to examine both cartridges and to visually see the differences. For more information: email Don Schimpff at guncollector@att.net
The .357 has a longer case and a heavier bullet; it is identical to a .38 in diameter but far more powerful. This is why a .38 will fire in a .357 but not the other way around.
Bullet diameter on a 38 is .357; on a 380 it is .355 Case is longer on a 38.
If by 38 you mean the 38 special , the answer is yes , as both use a .357 dia bullet
Assuming we're talking about .357 magnum and .38 special revolvers, the most basic difference is a .357 magnum chamber is slightly longer than the .38. The .357 casing is also slightly longer than the .38 and holds more powder. The actual bullet (the piece of lead) is the same, but because of the higher pressure of the .357, the bullet travels faster and has more energy. .357 magnum guns are typically a little heavier than a similar gun in .38.
The main difference between a 9mm round and a .38 round is their diameter. A 9mm round has a bullet diameter of 9mm while a .38 round has a bullet diameter of .357 inches. Additionally, the 9mm round typically has higher velocity and energy compared to the .38 round.
NO, a 38 Special is actually .357 caliber. NO, a 38 Special is actually .357 caliber. A 38 special is NOT a 357 magnum. Both bullet heads are about .357 in diameter. The difference between the 38 and 357 is the length of the brass case. The 357 brass case is a bit longer then the 38 special case, and the gun powder load is a bit higher then the 38 special load...... Further, you can shoot a 38 special case in the 357 magnum revolver, however, you cannot fire a 357 magnum round in the 38 special. The 38 special cylinder is too short for the 357 round......
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.
caliber 38 is a caliber 38. bullet dia. is .357 caliber deals with the dia. or measurement around the bullet head, not the bullet case.
The actual bullet diameter (as well as that of the .38 Special) is .357.
357 case is @ 1/10 of an inch longer.
.38 Special is a rimmed cartridge, designed for revolvers, while .38 Super is designed for semi auto pistols, and uses a recessed canneleure, rather than a rim. Additionally, the .38 Super has a bullet diameter of .355 inches, vs. the .38 Special's bullet diameter of .357 inches.
