Bullet cavitation

[9245]

At what velocity does rifle cavitation (wounding) occur? In other words, how slow does the bullet have to get before it starts leaving pistol like wounds?

The puncture itself will cause wounding. Do you mean a Temp or Perm Stretch Cavity?

At pistol like speeds I would say. With differences from case to case depending on projectiles' tendency to tumble or/and expand

Bullet design weighs a heavy hand here. Expansion and frontal area combined with velocity really answer the question, but generally 1600-2200fps range is where you can start seeing more dramatic temporary cavities with expanding bullets.

FMJ's rely on fragmentation and yaw/upset to get anything other than pencil-holes until impact velocity gets stupid fast.

Bullet design matters. It's probably one of the primary things to consider. Velocity needs for bullet A will not be the same for bullet B.


There is also a number of ways that wounding can happen.

243 and 25.06 move around 3200 feet per second on some factory loads ,my 243 just nails woodchucks to the ground the 06 make them look like a horror movie on the other hand my AK ,s using fmj mil spec move around 2100 fps and have been killing for 80 + years
