What is better for pure stopping power 308,30-06,300wsm?

Answer 1

Using the same bullet in all three, the 300wsm, purely because of the higher velocity therefore higher energy.
Bullet choice in this instance is important, as to use all of its potential energy, the bullet has to stay in the animal, a bullet that travels straight through and out of the other side releases very little energy.

Answer 2

Let's break it down:

.308 Winchester 180 grain bullet develops:
2,610 fps velocity.

.30-06 Springfield 180 grain bullet develops:
2,700 fps velocity.

.300 WSM with a 180 grain bullet develops:
2,970 fps velocity.

With the bullet diameter, bullet weight and bullet design being equal the fastest bullet will develop the most kinetic energy. This energy translates into stopping power. The bullet with the most stopping power is the one that dumps the most energy onto its target. Depending on the target the fastest bullet may not be the one that dumps the most energy. It could pass through-n-through dumping minimum energy, say like on a small deer. On a heavy boned animal like a Moose, Elk or bear the fastest bullet will have the most energy to deliver its the target... So in this case the .300 WSM has the most raw stopping power.

Best.

Answer 3

it won't make much difference being that they are all the same calibre and will be more a case of bullet weight and just what you want to stop.

if you want to stop small game quickest you will want a fast expanding bullet.

If you want to stop really big game the quickest you will want the heaviest bullet you can in 30 cal which will be 220-250gn


and as the others say the edge will come down to the fastest case the 300wsm, since it will push it a little faster than the other two.

Answer 4

Going off pure muzzle energy, I guess the .300 Mag. I'd say that any of these would be able to put down most game animals, though.

Answer 5

Of the choices you mention, the .300WSM, because it has more velocity and energy. Although velocity and energy are not reliable indicators of stopping power, more of either one can only help (assuming the bullets you use are sturdy enough to stand up to the impact velocity that they will have without fragmenting).

Answer 6

Forget about stopping Power, its really all about bullet placement, no matter what caliber you are using.*

Answer 7

Depends on who is behind the gun.
