Thumb said:I was wondering if you can buy hollow point bullets such as the ones used in the Liberty Civil Defense rounds +P .45 ACP 78gr hollow points or any other caliber?
At about $30/20rnds I think it would be cheaper if I could reload some so I could practice with them
Thumb said:OK, no problem with using those mentioned, I just wondered if the ones I mentioned were available.

Plenty of inertia with fast bullets.
Since E = MV²
doubling the mass only doubles the energy and tripling the mass only triples the energy
but doubling the velocity increases the energy 4X and tripling the velocity increases the energy 9X.
If I can't use a grenade, I'll take a fast bullet. At 1900 f/s, I suspect those 78 gr HPs are ugly.
Catfur said:Inertia is momentum, not kinetic energy. Momentum is MV, not 1/2MV^2. High energy, low inertia bullets (low sectional density) tend to dump all their energy quickly, causing lots of damage, but not penetrate deeply, making the damage extensive, but superficial.
GotRDid said:For any bullet to do the work required to neutralize a threat, it has to hit the target. All above mentioned alternatives are excellent choices, and it truly comes down to how well you (the driver of that bullet) perform under such intense pressure.
As for too much penetration, I can't see any problem with the bad guy leaking from two holes. I will, however, assume one has done the tactically sound assessment of the surroundings before firing the first shot.
