Smyth Busters: Will Excess Bullet Setback Blow Up Your Gun?
Repeatedly chambering rounds can cause bullet setback, pushing the bullet deeper into the case. This reduces internal volume, significantly increasing chamber pressure and risking firearm damage or catastrophic failure ('KA-BOOM'). Different firearm designs, like the 1911 with its steeper feed ramp, are more prone to causing setback than others, such as Glocks. Proper handloading techniques, including adequate neck tension and crimping, are crucial to prevent this dangerous phenomenon.
