YOU FIND A GOOD GUNSMITH AND PAY HIM TO CHANGE IT, THEY SCREW IN AND GUNSMITHS HAVE SPECIAL TOOLS TO SAFELY DO THIS TASK. WOULD YOU TAKE YOUR CAR TO A MAILMAN TO HAVE HIM CHANGE THE ENGINE??... PAY A PROFESSIONAL THAT HAS INSURANCE FOR THIS VERY SPECIALIZED WORK.......

I have to agree with the above. To do this without damaging the frame of the revolver, you need a device that clamps the frame in a vise without damaging it, and a special very LONG wrench that will grip the barrel. A smith will also have the knowledge of how to work a penetrating oil int the joint to break them loose, which barrels have a pin to secure them, and which ones have a left hand or right hand thread. The tools to do this right will cost several hundred dollars- and you may still wind up with the front sight on the side of the barrel.
Beginning of the barrel to end of barrel.
Yes, barrels can be changed. However, unless you have a Dan Wesson that is made to have quick change barrels, this is VERY difficult for the average hobbyist to do without doing serious damage to the revolver. It takes some specialized tools, not just a heavy vise and a pipe wrench. Find a gunsmith in your area, and talk with him.
Yes, that is a fairly common barrel length.

A rifle that has barrel removed- not likely. Revolver that has barrel removed- VERY likely.
A bullet that has left the barrel has marks left from its travel down the barrel.
It should be marked on the barrel.
