A method of manufacturing a barrel segment for a barrel, characterized by the method including the following steps:
- i.) arranging a capsule assembly so that it surrounds a template core (20), where the template core is fully or partially arranged with rifling for embossing rifling patterns on the barrel segment,
- ii.) arranging powder in the cavity between the capsule assembly and the template core,
- iii.) pressing the powder so that powder and capsule assembly are joined, and
- iv.) removing the template core in order to produce the barrel segment.
Method for manufacturing a barrel, characterized by the method including the following steps:
- i.) heating up a barrel casing
- ii.) arranging a first barrel segment including chambers, in the heated barrel casing and
- iii.) cooling the barrel consisting of the barrel casing arranged with barrel segments.
