Re: Bullet question!
American ammo designations have historically been done by marketing departments not engineers. Thus there is a lot of confusion about calibers. A US 38 caliber barrel is actually 0.357" not 0.38" or 0.380". A 357 magnum is an extra long and extra powerful 38 Special. Thus, you can safely shoot 38 specials in a 357 Magnum; but the 357 Magnum will not go all the way into a modern 38 special chamber. It will go into some very old 38's and will likely wreck such an old revolver when fired as the pressure is about 3X normal.
The 38 Super will not go all the way into the chamber of either the 38 Special or the 357 Magnum as it is too fat at the rear.
