Ballistic gelatin testing results : .223 Remington
Just got done testing a 53gr. Barnes 'Triple-Shock' bullet in ballistic gelatin.
The bullet penetrated 15.5" and ended up as 0.419" in diameter. The impact velocity was not taken (chronograph malfunctioned due to failing light at the test site), but the cartridge was handloaded to maximum SAAMI pressure using Varget powder ~ 25.5gr and using CCI small rifle primers.
Firearm had 16" barrel with 1/9" twist.
The block calibrated at 10.4 cm BB penetration at 596 ft/sec impact velocity. So it was slightly less resistive than 'ideal' muscle tissue. I will shortly have a penetration depth correction formula and will update this post with the corrected penetration depth, which is the depth to which the bullet would have penetrated in an ideal block.
