Slow-Motion Video Shows Bullets Pass Through Muzzle Brakes

Proof Research High speed photography muzzle brakeIf you want to see how a muzzle brake really works, definitely watch this remarkable slow-motion video compiled by Proof Research.

This amazing video features a variety of firearms: suppressed 9mm pistol, .338 Norma rifle, .300 WinMag rifle, 12ga comp’d shotgun, plus an AR15 and AR10.

This Must-Watch Video Has Some Amazing Ultra-Slow-Motion Segments

Watch the ultra-slow motion segment at the 2:55 mark and you can actually see a .30-cal bullet spin its way through the muzzle brake, leaving trail of flame that blows out the ports. Interestingly, at the 3:10 mark, you can also see a bright “afterburn” ball of fire that forms a few inches ahead of the muzzle milliseconds after the bullet has left the barrel. Perhaps this is late ignition of unburned powder?
