Killing Power?

Caliber increase just gives a slightly bigger hole ( provided it impacts at a high enough speed to expand ). The thing is though with an increase in kinetic energy , we get increased recoil and this needs managing via a good "stance/ position / hold" and "a heavier gun" to handle the
recoil. To increase the carry weight increases fatigue in the person carrying it . If you dont think this matters try shooting a real nice group off hand straight after 20 good push ups!
Stepping out of a truck and shooting off the bonnet with a bag / bipod etc is one thing carrying it up a steep face is quite another matter . Taking fast off hand standing shot opportunities after exercise another .
Light rifles , less recoil , lighter bullets with a bullet that is going to do the job if you do is my way . Its certainly true a heavy gun firing a heavy bullet can stem a lot of the recoil but its an SOB to shoot fast and accurate off hand, kneeling or fast improvised positions and they certainly sap your energy and tire your muscles.
To say a heavier gun is more accurate is true that's why weight limits are applied in most competitive shooting . Carry a heavy bench gun up a long steep face and try a standing shot with it though? .... !
 
Yes but not as far.....lol

Plenty have been lost also, that includes other calibres but not as many as the .22.

Having shot a fair few deer with a fair range of calibres I really know from my own experience that the wallopers out wallop the non wallopers.
Aye, going up in level above standard cartridges definitely gives more whallop John, I get that.
I'm refering to the splitting of hairs between the standard cartridges often used here. Not much in it then.

Aye, your right, like the post of a large bullet you posted the other day found in a healthy deer and my reply of my account of finding a 22 in a deer.
**** happens...

One doesn't have any thoughts of any of the above when the pi$$ed off thoroughly enraged Cape Buff is closing quickly.

Btw the OP was about 'killing power"
 
Point 3 of FInn Aagaard's article provides the best summary of his views: practice field marksmanship and understand animal anatomy rather the putting all your faith in a big calibre.
 
I don't agree. Additional bullet weight means that more of the front of the bullet can be "lost" as there still remains more bullet that isn't lost. That's to say that a 100 grain bullet losing half its weight is now a 50 grain bullet. A 200 grain bullet losing half its weight is now a 100 grain bullet. Also the argument that, seemingly, penetration is sufficient means that we could kill a deer, dead right there, with a knitting needle slowly pushed into the lungs? No. For without velocity to "scramble" the lung tissue penetration is not it itself an instant killer.
100%. I’ve got a taxidermist friend who accidentally pierced her rib cage with a long very thin needle - she felt completely fine but went to hospital and they confirmed it just kissed her heart, but no damage was done. If she’d done the same thing with a sharp bit of 5/8” rod she wouldn’t have failed so well. Marksmanship is obviously important but to claim wound channel is irrelevant makes you appear ignorant
 
I can just hear hydrostatic shock, knockdown power, and energy dumping telling Santa and the Tooth Fairy that they are away over to SD for a couple of hours for a bit of a laugh but they'll be back for dinner.
 
I think no one would argue that if you put a bullet in the right spot, the animal falls over.

The confusion begins (1) when you start trying to define what the right place actually is; and (2) when you start trying predict what happens when the shot isn’t in the right place.

I’m willing to believe there is some sort of effect that roughly approximates to what people mean when they talk about ‘knockdown’ power. I have a short barrelled Creedmoor that shoots factory ammo at a rather slow 2550fps. If I shoot roe deer in the chest (not hilar, not shoulder) out to about 100m, they usually collapse instantly unless alert. If I shoot them in the same place beyond about 150m, they usually run a bit. Same bullet, same shot placement. Sample size in the hundreds now. Since the only change is the terminal energy of the bullet, then the difference must be caused by less energy being imparted to the carcass. I have no idea how that difference translates to causing the animal to collapse or not.
 
FWIW neither is velocity alone, or at least the velocity we get from standard hunting rifles, a killer. Elmer Keith did some field tests using lathe turned solid bronze bullets in what was, back then, the fastest smallbore centrefire. Possibly the .228 Savage. He found the bullets accurate but that they did not kill or in many of the rabbits he shot or he claimed even cause them to seemingly react to the shot.

Having said that I attended a talk thirty plus years ago on conclusions of gunshot wounds from the Falklands War. The first part of which was to begin the lecture with the speaker picking up a .303 No.4, that the Falkland Islands Defence Force were equipped with, and saying that that could be discounted as nobody was actually shot with one. His conclusion was that best killing effect was a fast AND heavy bullet.

But if the choice was one or the other that a fast light bullet was better than a heavy slow bullet. This was because the fast bullet was more likely when it hit bone to shatter the bone and cause that to become secondary projectiles. And that if the bullet broke apart then, again, the shards or jacket and core from a fast bullet would cause more damage than the same from a slow bullet.

Although interestingly he also noted that the "myth" of the lethal velocity alone destructive power of the 5.56mm was just that. A myth. That the worst case wounds seen with 7.62mm NATO were always worse than the worse case wounds seen with the 5.56mm. His last words of advice were to "fight naked" in that (wearing) thick webbing was not your friend if it got hit with a bullet.

5.56mm in military terms is intended to enable a man to carry more rounds (30 rd mags rather than 20 with 7.62) and then incapacitate the enemy, not necessarily kill him (two further men to carry the wounded man away). 7.62mm - bigger holes and more impact, "if it doesn't kill the enemy it at least knocks bits off them", as a Para said to me post Falklands. Same reason I prefer a larger calibre for deer.

I’ll just leave this little illustration here.

Aye, or experts thought they should cover their arses hence we have a normalisation of now thinking we all need a sledge hammer to crack a nut when in actual fact a 357 magnum would probably suffice most of the time for the majority of shots.
.357mag are legal for roedeer in Sweden, works for short distance shots driven by shortleged dogs.
 
Agree to disagree there I think.

Personally I would say some people have a normalisation over how much a deer should run, partially driven by the idea a .243 or 6.5 is the 'big rifle', when in reality it's pretty marginal for the job.
My view is any deer making it beyond 10M or more is an excessive run, so by using appropriately sized calibres and bullets I can curb the typically run distances to well beneath that, even at extended range.

I see no tangible benefit to going beneath a 6.5 when recoil is already non-existent and terminal performance is already noticeably weaker than seen in the slightly larger calibres.


Ben
For me its ok if a roedeer or moose has run up to 150m which is normal after a lungshot with popular calibers between 6,5*55 to 9,3*62.
 
Its quite simple really, whacking big stag bodies with a .338 win mag rather than a 6.5 wonder cal results in 'bigger is better'. But then we have the " I've shot lots of deer with a .22."......ok!
I had my .308 Norma mag with me as I was taking his pic, a calibre with 'wallop'
Take two 180 grain projectiles used in two proprietary calibres.
There is no doubt a .308 Winchester 180 gr would also do the job but when the foot pounds difference of the Norma 308 Mag enters the field the extra 800 odd ft-lbs certainly makes a difference. The bigger magnum calibres do have more of the knockdown effect.
Frontal area of projectile is the same.
Bigger can be better.....Tyson hit harder than middleweights.

I agree and dis agree with most of the comments above. Yes, shot placement is vital. Correctly placed you do not need a large calibre or more and more bullet weight to make a clean kill. My point though, is that not every shot goes where you want it to all the time. A slightly "wayward" shot from a smaller calibre, or less weighty bullet, may not result in an instant kill. A larger calibre, and/or heavy bullet has more room for error.
