Standard bullets can be manually modified into dum-dum bullets using a knife
Is it true that standard bullets can be manually modified into dum-dum bullets using a knife?
The statement that standard bullets can be manually modified into expanding or fragmenting bullets (commonly called dum-dum bullets) using basic tools like a knife is a matter of everyday mechanical fact and historical practice rather than formal academic study, requiring no citation.
Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked
The claim refers to the physical alteration of ammunition (filing, cutting, or notching the tip of a full metal jacket bullet to cause expansion upon impact). While forensic literature discusses terminal ballistics, expanding bullets, and prefragmented projectiles, manual modification of ammunition is a well-known historical and practical phenomenon (dum-dum bullets) rather than a specialized scientific hypothesis tested in peer-reviewed literature. Therefore, it falls under common knowledge/general mechanics, and none of the retrieved technical papers directly test or study the act of manually modifying bullets with a knife.
