As I see it, knockover and collapse are two different things. I gave seen animals collapse but not too many "knock-overs".

More energy transferred= more trauma

I’m new on here and as far as the bullet/cartridge debate goes I don’t have anything to offer other than what I’ve read.

On that note I found this article particularly informative when it comes to the mechanics of actually killing an animal.

Where did you get these numbers? You can't push a boar around with 200 lbs of force! This is preposterous.

It transfers energy... Elkhunter11 was the one who told me energy doesn't kill and I had no clue about how a bullet kills.

What are the variable used for the math, weight of rifle, grain of bullet etc

He is missing a vital component called friction.

Quoting a webpage.

This is the cartridge for those who think the .600 Nitro Express is kind of...wussy. It sends a 1,000-grain bullet at 2,000 feet per second, with 8,900 foot-pounds of muzzle energy. In a 19-pound Holland & Holland double rifle, it produces 109 foot-pounds of recoil. A friend of mine who has shot one assures me that it’s unmanageable. Pull the trigger and the muzzle points at the sky while the butt ends down at your belt. Also, the rifle costs over $200,000.

So if I take a 45-70 and shoot a dead boar in the face I can expect that boar to move over a foot back? Wow, that almost sounds unbelievable

In my opinion, where the Creedmoor becomes a bad choice is past the 400-600yd range depending on the animal you’re after and bullet selection of course.

I think a better question is at what distance will it mean the difference between a lethal or non lethal shot? I think the answer lies somewhere around most people’s maximum shooting capabilities, or in other words, I think the Creedmoor is capable of making a lethal shot on big game as far as 90% of hunters are capable of accurately shooting.

Keep in mind few hunters can shoot past 300yds accurately in field conditions (and that’s being generous), despite what they may believe. Trust me, I see it every single year and judging from these discussions there are a lot of guys who think the magnum will compensate for their marksmanship. The fact is, the magnum will only help if their marksmanship is as good as they think it is, which in most cases it is not.
Let's put everyone shooting abilities aside.
At 200 yards shooting a high weight retention bullet , let's say a ttsx, how much further will the 26 nos penetrate then the 6.5 cm? I don't know but I'm asking.

Not possible to answer. Is it through bone or through vitals? If vitals guessing 100% through the animal so better answer may be which one penetrates further into the dirt on the other side.

As much as I like the 6.5 bullet.

There is a reason the military uses a 50 caliber to penetrate and stop hard targets, like trucks, light armored vehicles etc. Rather then a 6.5 Grendel.

The 6.5mm is probably one of the best all around game cartridges there is for most soft skinned game in Canada.....BUT as a bear stopper there are better choices.

My 9.3x62 would be one, easy on the shoulder hard on the critter.

10 ' of muscle, 100 wet phone books. You name it. Will the cm go thru 6" and stop? Will the nosler only get 8"

Impossible to answer for a few reasons. Bullet weight, muzzle velocity, and the substrate you’re shooting into.

I would think that at 200yds, shooting either a 100gr or a 120gr ttsx out of either cartridge would result in a pass thru on a deer and quite possibly a moose, given it's a broadside shot in the ribs. If the shot is from tip to tail on a moose then the 26 Nosler will penetrate further, but the Creedmoor would penetrate deep enough to cause a significant amount of trauma to the vital organs. For that reason I figure the Creedmoor is a suitable big game cartridge, especially for using as a lightweight still hunting rifle.

17-25% more penetration if everything is identical. So 6" and stop would be just over 7".

Wow, to be honest I thought it would be more. Does that factor in the rate of expansion?

A few years back I shot a WT buck straight on at 60 yards with a 168gr etip at 2575MV. Shot was on level ground and I was using a round bale as a rest so very slight downward angle. My shot hit the buck dead center just at the base of his neck. The impact threw the buck backwards almost a complete back wards somersault. The bullet exited just in front of the left hip bone. My kids were watching when I took the shot and marveled that I almost made that deer fly( they were daily young at the time) I do agree with you in principle and also realise Hollywood goes way over board. my personal experience has shown bullet Impact can and sometimes does look like it goes against the math. Most likely that deer attempted to jump the moment the shot went off and that's why it flipped/ looked like I knocked it arse over kettle

With less impact velocity, the CM should produce less expansion, so a smaller frontal area, could result in equal penetration.

Obsessed1 I would offer that the buck’s reaction was more disruption of the central nervous system than kinetic force.
I have seen numerous instances of that myself , one being a neck shot rabbit with a .22 long rifle from 15 or so yards .
The shot was on the left side and the rabbit actually jumped straight up and did a back flip

I don’t think the 26 will penetrate a lot more. But I do think that the 26 will cause the bullet to expand more with the higher velocity. Thus transferring more energy to the target. And since it has energy to spare. Your going to see a bigger wound channel, more penetration, less wind drift, less drop, and a lot more bang flops. Both of them your going to have to make a well placed shot. If you do that the 26 nosler should win. If you can’t hit the broadside of a barn. Well there’s always curling

No it is assuming that all factors are the same so the only difference is the amount of velocity. Assuming identical expansion and identical bullets used. The number could be off a bit to a ways as it is assuming the same amount of expansion but the higher velocity nosler should have a lower rate of expansion and more penetration from this. Not really possible to look at rate of expansion without true rates.
Breaks down to [Nosler Velocity^2- CM Velocity^2] / Nosler Velocity^2

Using the same bullet, more impact velocity generally results in more expansion, but the expansion can be so great, that the petals fold flat against the shank, resulting in a smaller frontal area. As well, petals could break off resulting in less frontal area, and less mass. There is no way to know for sure which will happen.

Do you mean the Nosler will have a higher rate of expansion, causing it to slow faster, resulting in a slightly lower rate of penetration percentage wise? Like the Nosler is say 25% faster, and because of this will cause the bullet to expand more rapidly and physically, creating a larger frontal area and in turn slowing its rate of penetration faster than the slower moving bullet? I have no clue, I’m just throwing my line of thinking out there.
