Using a short barreled rifle will have multiple effects on ammunition performance. Hornady Ballistics Engineering Technician Jayden Quinlan explains and demonstrates how SBR's affect muzzle velocity, bullet stability, terminal performance, and safety concerns as well as how twist rates and bullet length influence stability. Field tests include velocity difference through a chronograph and target impacts of stable and unstable bullets. Ammunition recommendations are given for barrier and non-barrier performance in SBR's.
