Hahaha no that was on steel, there's no enjoyment In hunting at that range for me (each to their own) although I have shot living things a fair bit further than that in the past.
6.5 Creedmoor different round for different deer?
- Thread starter PEM406
- Start date
Interestingly, I was reading an article about this years ago, that sought to understand this phenomena. Their test case was culling buffalo, but it was the same question: "Why do some drop straight away, and why do some run, even after having their heart destroyed by a bullet?"
So, when they culled buffalo, they perform necropsies on all the carcasses in a hope to find out. What they found was that when a buffalo dropped straight to the ground from a heart shot, there was severe destruction of the arterial valves in the carotids that fed blood to the brain, as well a damage to the brain itself. And in those that ran, there was less, and in some cases none, damage to these arterial valves.
The overall theory was that it had to do with the bullet striking as the heart happened to be compressed, while the arterial valves were open, or beginning to close as the heart relaxed. With the valves open (allowing blood to pump down the artery), or just beginning to open, they suspected that a hydrostatic shock wave traveled up arterial pathway and directly into the brain. Causing severe hemorrhaging of the brain and destruction of the main arterial pathways. But, if the heart was already relaxed, and the arterial valves were closed, this inhibited the shock wave travelling up into the brain, which then allowed the buffalo to bolt until the brain eventually ran out of oxygen.
At any rate, I thought it was an interesting experiment/theory, that made sense when you think about it.

That's really neat and does make sense.
How do you spot what stage of the cardiac cycle a deer is in before you shoot?
And can @Danny25790 do it at 1,200m?<chuckle> And therein lies the problem.That's really neat and does make sense.

Like I said, I thought it answered the question. But yes, there doesn't seem to be an easy way to take advantage of that theory.
My own experience is its awareness of danger , when the adrenalin is flowing they tend to run . That could be a rutting stag who doesn't know humans are about or any 2nd , 3rd and , 4th etc , etc from a group during culling . Its all interesting stuff though . The only thing that puzzles me is the weird ones ( those that break all the normal expectations )
Indeed. The ones that go berserk, kicking and spastically contorting into a flurry of hooves flying, are always the ones that leave me thinking "Well. That was certainly different."
Weird ones ! Had a roe Brain shot flip backwards doing a fosberry flip over a deer fence it wouldn't been able to leap in life ( or rather wouldn't risk it forwards the right way up ?)

I think I stumbled on my "standard" round for all species quite by accident. To me it was a case of find a round that my rifle (a semi custom Rem 700 in 260 Rem 1:8 twist Bartlein 26") liked and planted one on top of the other consistently. The heavier 143's hit harder and the lighter ones go quicker, so a happy medium was Sierra's 130 grain Gamechanger or Tipped Gameking as some call them. They have done the job on everything and more importantly for me at least, they go exactly where I send them. Ethical, accurate, well placed shots have got to be the priority surely? They'll all drop if we hit em right 
As an aside, I came across this on 65 Creed. Interesting stuff.

Shame Dodgyknees is no longer with us.
He would appear round about now to tell us about the hilar zone…
I think I know the very fella LOL . Take the best shot placement that will get the job humanly done that you see , because it might well be your only chance to take one !

Interesting video, thanks for posting it.
I am a big fan of Ron Spomer - he is a very experienced hunter and a good presenter. I think his comparison between the 6.5 Creedmoor and the 6.5x55 however is slightly flawed as he may be quoting from the Military 6.5x55‘s performance rather than the modern hunting 6.5x55SE which in performance is pretty much identical to the CM, shoots the same bullets and on occasion even exceeds it - at the cost of a tad more powder.
Worked yesterday evening. Long grass also a factor. He came closer than this, went broadside then dropped straight away. Not sure what the mark is very high in his shoulder because the shot was lower than that.
Attachments
I would not get too attached to using any lead bullet at present . In deed I have ELDX and Various 6.5 mm Lead bullets sat mainly gathering dust .
Even when i am not compelled to use none Lead i tend to use the Copper
Even when i am not compelled to use none Lead i tend to use the Copper
And that’s a whole other side to it. I got the CM because of concerns with non-toxic in the 243, so will be taking a good look there once the excitement of a new rifle settles down.
They are both simple cup and core . ELDX is a higher BC but heavier bullet . Your going to be shooting copper soon regardless of your choice now , you still will be told on venues " Sorry no Lead "
100 grain TTSX 6.5mm is brilliant , Best bullet i have shot on deer 120 TTSX is next and this would be my 2nd choice though I am on lower numbers to them . 100 beats the 120 on speed by 450 fps and is we look at 300 yards plus that's a fair factor in ability to expand well 3300/2850 at the muzzle ! Copper does need to impact fast enough .
We are all going to be on copper soon enough, is it wise to build your loads on a new gun around something that really wont be with us on the deer very much longer ?

A friend of mine had a 308.
Used 150gr Nosler.
He used N140.
2 different powder charges.
Tried and tested for years successfully.
A Highland load for all large species.
A Lowland load for all small species.
He kept them in different ammo boxes and permanent markers each one so no mistakes.
I'm sure you could try the same thing with your chosen rounds.

I totally get what you are saying, but without wishing to be rude, that doesn’t really answer my question.
For the time being I’ll be using lead and the 129g Superformance SST is one of the two hunting rounds that my local gun shop stock, the other is Federal Power-Shok 140gr Soft Point.
I can get the ELDX rounds but that is a 2hr round trip hence my curiosity as to how people have got on using 129g Superformance SST’s.
