Sierra 115gr 9mm JHP Ballistic Gelatin Test & Review
This ballistic gelatin test evaluates the Sierra 115gr 9mm JHP. The test reveals inconsistent expansion and significant penetration issues, with some rounds passing completely through a 10% ballistic gelatin block even after passing through denim and t-shirt barriers. The instructor notes that only one out of three rounds expanded through denim, and expansion was minimal. The test highlights potential limitations of this ammunition for self-defense applications requiring reliable expansion and controlled penetration.
