How to measure barrel length? Do you measure from the end of the barrel to the end near the firing pins? Does barrel length include forcing cone? Thanks!
A gun barrel can be measured by taking a metal rod and wrapping it around the barrel. Once it is wrapped around the barrel, mark where the two ends meet and use a ruler to measure the distance between the marks. This will give you the circumference of the barrel. Next, divide this number by 3.14 to get the diameter of your barrel. Finally, to get the length of your barrel, measure from the muzzle (the end of the barrel where the bullet exits) to the breech (the end of the barrel where the cartridge is inserted).
Here’s a step-by-step guide on how to measure a gun barrel using a dowel rod:
1. Get a dowel rod that is the same diameter as the gun barrel.
2. Insert the dowel rod into the gun barrel.
3. Mark the spot on the dowel rod where it intersects with the edge of the gun barrel.
4. Measure the distance between the mark and the tip of the dowel rod. This is the length of your gun barrel.
