No, the bullet will not seat.
No.
No
You can from some, but they have to be designed to shoot both.
No. They are not designed to fire a 17 cal bullet
Somwething like this, 223 or 224 diameter bullet is 22 cal. 243 or 6mm is 24 cal 257 is 25 cal 308 is 30 cal and so on. There are some bullet diameters that cross over the caliber lines.
Generally speaking, no. You can only fire the caliber for which the gun is chambered. There are some exceptions, but not many.
I havenever heard of a .54 cal but no, a bullet that will not stay in place for the striking pin will not fire, DO NOT TRY IT, if by some off chance that the striking pin hits the firing cap then the bullet has already started its trajectory at an angle and will probably damage the gun and yourself, it will be hard to find but you may be able to find a a saboe for that caliber, but you may just want to go buy some .54 cal ammo...
They will "fit" but they will not fire correctly, and will break when the bolt tries to push two of them at once.
If you mean a .40 caliber bullet in a .32 caliber gun- no. The bullet would be 8 thousandths of inch too large to fit in the gun. Caliber refers to the diameter of the bullet, so a .40 caliber bullet is ABOUT .40 inches across, and a .32 bullet ABOUT .32 inches across.
very, during gun safety as a child, I saw a video that showed how a .22 cal bullet can bounce, around the body and tear it apart.
No
