300 Blackout in 4 Guns: 2 AR Rifles vs AR Pistol vs Bolt Action

In this episode of Handloader TV, we put the 300 Blackout to the test across four different platforms: two AR-15 rifles, an AR pistol, and a bolt-action rifle. Each setup brings its own strengths, but how much difference does it really make when it comes to velocity, accuracy, and real-world performance? We tested both subsonic and supersonic loads to see how the 300 Blackout behaves across barrel lengths and action types.
