Referring to groove impressions left on the bullet as it travels through the barrel (known as "striations")? Absolutely, just like any other projectile.
If you are unsure, take it to a gunsmith. There are more than one type of "38 bullets"
38 or 357
Yes
no the 38 bullet is fatter and and the special is smaller
It is possible.
No, but a 38 special will work in a 357
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.
It might not be chambered for 38 special.
44 bullets are larger. More mass = more damage. A 38 will keep its high velocity longer because smaller bullets travel faster. But if you were to get shot by one, 38 will do less damage.
Two to six, depending on the make, model, and type of firearm.
No it can not be traceable
Typically, it holds six rounds.
