What manufacturers use hammer forging to produce high-strength alloys for weapon barrels?

DSIAC staff performed open-source searches for manufacturers and/or foundries and mills that produce hammer-forged ingot barrel stock, barrel blanks, or barrels. Then open source searches were done on metallurgical technologies and/or manufacturing processes that improve barrel durability while maintaining accuracy. The findings were compiled in a report detailing general barrel manufacturing processes and benefits and drawbacks of various portions of the process, along with an appendix containing a list of manufacturers using hammer forging to produce gun barrels.
