Centerfire rifle rounds will -always- out-penetrate pistol loads using the same weight of bullet, assuming no exotic (MagSafe, Glazer, Green/Frangible) exotic bullets are used in the rifle.
Rifle Bullet = Fast, pointy, lots of sectional density, 1,000+ ft-lbs at the muzzle.
Pistol Bullet = slow, blunt, not much sectional density, 500 ft-lbs at the muzzle (maybe**).
The one exception to this is firing into water, where a rifle bullet's higher velocity and greater kinetic energy will cause the bullet to self-destruct. Pistol bullets hold up much better. |
Had to call you on this one, mate. Though the statement regarding equal weight is accurate, most people will be using a 55 or 62 grain bullet vs. well over 180 grains for almost all .45 ammo. Most 5.56 will fragment almost instantly upon hitting drywall or sheetrock, and loose much if not all of it's lethal potential after passing through the second sheet. It is a pretty damn good home defense round, especially since most home defense situations will put the rifle within range to deliver the neccessary 2200 fps needed to assure proper permanant cavitation (ie a clean kill).
