I couldn't find the shear strength of gold, so I will use some other values from this website.
Compressive Strength and Modulus of Rupture (205 j/cc) = 5.300316e+7 Joules or 0.013 Tons (Small Building level)
Tensile Strength (220 j/cc) = 5.688144e+7 Joules or 0.014 Tons (Small Building level)

Nightwing dodges a bullet (Episode 5)[]
Feat starts at 1:45

Nightwing's face - 0.29 meters and 359 pixels
Height of the gun - 0.127 meters and 176 pixels
Screen height - 732 pixels
2atan(tan(70/2)*(359/732) = 0.456648331072 Radians
0.456648331072 Radians - 26.164022092 Degrees
Plugging that value into this calculator, and solving for distance.
Distance to Nightwing's face - 0.62399 meters
2atan(tan(70/2)*(176/732) = 0.22686724789 Radians
0.22686724789 Radians - 12.998535814 Degrees
Distance to the gun - 0.5574 meters
0.62399 - 0.5574 = 0.06659 meters

Nightwing's face - 0.29 meters and 204 pixels
Height of the gun - 0.127 meters and 172 pixels
Screen height - 732 pixels
2atan(tan(70/2)*(204/732) = 0.262574370786 Radians
0.262574370786 Radians - 15.044403254 Degrees
Distance to Nightwing's face - 1.0981 meters
2atan(tan(70/2)*(172/732) = 0.221753812024 Radians
0.221753812024 Radians - 12.70555752 Degrees
Distance to the gun - 0.57036 meters
1.0981 - 0.57036 = 0.52774 meters
Distance between Nightwing and the gun - 0.06659 meters
Muzzle Velocity - 375 m/s
0.06659 / 375 = 1.7757333333333333333333333333333e-4 seconds
Distance Nightwing moved his head - 0.52774 meters
0.52774 / 1.7757333333333333333333333333333e-4 = 2,971.955 m/s or Mach 8.7336 (Hypersonic)
