Barrel repair
Once diagnosed that the barrel suffers from wear, it can be solved in two different ways:
1. The inner diameter of said barrels is increased as little as possible (according to wear) in order to have a chamber with a larger diameter but completely cylindrical and homogeneous.
2. The inner diameter of said barrel is increased until a bushing can be inserted. In this way, the barrel will remain at the nominal diameter, without any increase.
