witch gun is going to have more knockdown power on a white tail deer a 30/06 or a 7mm rem mag?

Answer 1

30/06 definatly your better choice good luck : )

Answer 2

To answer your question, when both are using identical-weight bullets, the 7 Mag will have about a 14% advantage in muzzle energy vs. the .30-06 (3221 ft-lbs. vs. 2820 ft-lbs). No deer will ever be able to determine this difference; I have shot several deer with each and really could not detect any difference in their effect on deer. I have also shot some deer with a .300 Weatherby Magnum, which provides about a 52% increase in energy over the .30-06 (4300 ft-lbs with the same bullet weight). At this level of performance, the difference is readily apparerent.

Answer 3

"Knockdown" power is a dubious concept applied to big-game hunting. Most animals will run for a bit when shot, unless the shoulder is broken. Bullet placement and terminal performance are far more important than slight differences in calibre within the .270-.280(=7mm)-.30cal. class, and given adequate penetration and expansion, bullets from 130gr. to 180 will all work at any reasonable hunting range. However, the lighter, higher-velocity bullets may fail to penetrate at very close ranges, while the heavier, slower, thicker-jacketed bullets may fail to expand at long range.

For sheer kinetic energy to produce instant knockdown, there are two schools of thought: the big-bullet theory, wherein a .600 Nitro-Express might be expected to fling a deer twenty feet through the air, much as a movie bad-guy hit by a blast of 12ga.; versus the small-bullet theory of hydrostatic shock, which contends that since any animal is largely composed of water, the highest-velocity bullet will, regardless of penetration, cause a shock-wave throughout the body, overwhelming the nervous system and producing near-instantaneous death. Although I do not doubt that velocity contributes something to the lethality of the .300 Weatherby or the 7mm UltraMag, the idea of using the .220 Swift on elk strikes me a trifle absurd, and when a charging beast MUST be stopped in its tracks, big, heavy, large-calibre bullets have proven themselves superior to the lightweight speedsters.

The real purpose of the high-velocity, medium-bore magnums such as the 7mm and .300 is to extend the killing power of standard calibers by up to 200 yards, not to blow things to smithereens up close. So try using a .458 with 510-gr. soft-points at 2200fps. for deer and let us know what happens.

Answer 4

Both shoot bullets, not artillery shells, so there's no "knockdown power" in them. They both work by producing a good wound in an important spot, if you put the bullet where it needs to go. There's a whopping 40th of an inch difference in the caliber, the sectional densities of the bullets available are equivalent, and the velocities translate into perhaps a whopping 25 yards' difference in effective range. The only significant difference is that many people are tempted to use the 140 grain 7mm loads at velocities that can exceed 3200 fps, and that will produce a bullet failure (surface explosion) on really close shots, but of course choosing a different load takes care of that problem.

Answer 5

30-06

Answer 6

I would say the 30/06

Answer 7

The 7mm Rem Mag will do it's job just fine, as long as you do yours. Practice and become good with it. Just remember to choose the bullet weight and design carefully. A light bullet such as 140 grains might not kill cleanly as it may fragment on a deer, and a heavy bullet in the 170 grain range might not expand and leave enough wound channel to kill cleanly. Choose something in the middle which is designed to open and stay together on deer sized game and you can't go wrong.

Answer 8

Absolutely the 30-06.*

Answer 9

They are ballistically similar so, most likely, the deer will never know the difference, but I have to say the .30-06 because it does shoot a wider slug.

Answer 10

Knock down is a Neophytes term which has no basis in fact. Terminal Velocity, bullet weight, projectile structure what type mass the projectile is penetrating (Bone verses muscle), Hydrostatic shock value and projectile weight retention. Oh and terminal energy dissipation.
When all these things become a known and exact formula, THEN you can determine, 'Knock down power.'

Answer 11

If you use an appropriate bullet in each, a good shot into the heart will kill cleanly enough that you and the deer will never be able to tell the difference.
