Copper distance myth

I’ve shot decades with lead, in most calibres and chamberings. I found over the years that lead can also underperform - example, lapua mega 156g in 6.5x55 on roe..about the worst I’ve ever seen in terms of runners! And many many more examples of soft points that were too frangible, etc. all about matching the bullet design and weight, to the intended game target and distance (velocity), as well as the POA the hunter opts for. The perfect round for situation X, but with neck POA, may be a poor choice for the same situation but POA shoulder.

Same goes with non toxic, and whilst I don’t have decades of experience with non toxic, I have been experimenting with many makes and weights and designs for the last 5-7 years or so, and, i do shoot a fair number of deer from Roe to Red.


One thing I can say, and you may not like this - in my experience with non toxic that’s been picked for purpose, and placed where it should, beasts take substantially longer to die, more pencils, more runners, and more needing follow up shots. Not ALL, but MORE, a lot more. So experimenting with shot placement as well, using the High Shoulder and Hilar shot, ‘had’ helped, but the non toxics are still not doing the same level of quick death work that say, the Nosler Partition did.


Many may disagree, but whilst I use non toxic and don’t eat lead shot game, I am open enough to admit I am not a fan of the terminal performance in comparison to lead based ammo.
 
Impact velocity surely?

Your MV might be high enough but unless you shoot them point blank thats not the relevant number
On the contrary, under field conditions there's no reasonable way of measuring impact velocity. I agree that in an ideal world that's what you'd do, but in practice unless you retrieve the spent projectile you are merely guessing at it. MV is the industry standard benchmark and guesstimates of impact velocity can be derived from this. In practical terms Barnes recommend MV of 3000fps in .243 with an ideal impact velocity of 2400 fps- or higher for both.
For the sake of clarity MV can reasonably be measured by batch testing on the range before setting off for the stalking outing.
 
Here's the issue.

I attended a meeting last night on lowland and urban deer management.

One of the speakers has 50 years of stalking experience and carries out a lot of urban deer management.
He told me that he has had a lot more runners with copper than with lead.
A good number of those shots had pencilled right through.

We’ll see what happens when there are a number of runners, in urban areas, that are witnessed by the locals and complaints start reaching M’s of P.

An attendee at the meeting said the best rounds he found, for expansion, cost £99 for a box of 20.
I’m happy to fire off 40 rounds of lead ammo at the range to keep my eye in.
However at those non-lead prices, that would change and so would the potential for more wounded deer.
Folks around 70 and onward are frequently stuck in an experience loop. Sure they known their stuff, yet shy away from new ways , i have one foot in the past . it took me a while to actually use the copper bullets I bought at the get go , yet now i have a load of lead bullets that i don't see myself using .
The bullet is perhaps the cheapest thing in stalking , yet brings the most .
I also shoot a good amount of small game with copper and i have shot all my wildfowl and game birds with steel . Indeed way before the lead ban i started shooting foxes with steel shot well before we had to loose the hounds
 
Had some blades on order for months as I wanted to try them

Found that THAC give me the performance I desired

Haven’t tried THAC - have shot deer with Barnes, Yew Tree, Blades, Virtus, Peregrine in .243, 6.5, .308, .30-06 and .30WM - they all work. I have found the Barnes TTSX 130 in .308 to be excellent - instant kills out to 250 yards and reasonable (minimal / acceptable) carcass damage. Never managed to recover one but did neck shoot a sika stag and found the below furrow behind him which appears to support good weight retention.

Video proves Barnes are effective on 10% density gel blocks when shot at 10m.....
Failing to take into account the not inconsiderable entry angle change on a 600m shot

Also that the decreased sectional density has a significant effect on terminal velocity at ranges over 500m
Something i have discussed with various manufacturers with regard to the BC of a pure copper, vs BC of a cup/core lead
The observed drop at 600m with a 200gr Peregrine from my 300nm was significantly different to the expected data
The only variable it can be is the BC
The impact of the 200gr copper vs a 200gr ELDX on the steel was also significantly lower.
No doubt 200gr at any velocity is going to put a crimp in your day but there is no way they hit the same at range
The expansion characteristic relies on velocity to expnd the bullet (rather than the exposure of a soft core)

I dont buy the "going to sleep" theoretical change in external ballistics

Good luck shooting Barnes TTSX/LRX at UK deer at 600m.
You will need to be absolutely on the money with a CNS centric shot.
Hope you have a good dog

Or learn some field craft and get closer? Or is that something only us "old folks" do?
 
Interesting ....
Demonstrating how often dont need to drive these bullets at full tilt .. especially on our thinner skinned deer compared to other countries deer and say boar




Surely thinner skinned, lighter game, are going to result in less expansion, due to less resistance?

Just shoot lead at the range and copper on deer.

Something you old folk do clearly 😂

Field craft is all well and good until you've got a heard of reds standing watch and you've got nowhere to go and no way of getting closer without giving the game away. One of the fields that predominantly hold reds on a bit I have, there is absolutely no way to get near purely because of the topography once you hit 300 yards from their usual spot. Come in from the other side and they've left before you see them because of wind.

Joys of shooting in valleys, always bloody windy

One of the fields I shoot is 1km long by 850 metres wide with no cover, just crops, the neighbouring field is similar. Being able to shoot deer at 300 yards or not is often the difference between shooting a deer, or not.
 
Just watched the video, the thing is he’s using a magnum cartridge to extend the velocity and therefore the range.

Launch those 150s from my .280 and the 700 yards becomes 550, from a 7-08 it becomes 425.

And that is only if Barnes’ BC is accurate, but BC varies depending on velocity, so slower cartridges will give a lower BC and those ranges will shrink back further.

So all he’s really telling us is if you want to extend the range of copper you need a magnum cartridge, which I think we already knew!

Even at that point, I personally think expansion is poor. 7-08 and it will have run out of steam after a couple hundred. Then you've got the lack of expansion on top 😂
