Best Calibre for Deer with Copper Bullets

The same calibres work as for lead, especially if you are home loading.

If you are shooting lots of red hinds on the hill (thus at longer ranges) and having to use factory ammo then there is, I feel a case to go up in calibres with non-lead.
There is certainly a case for buying a very commonly chambered factory deer carriage. . Only shot 30-40 reds so far stags n hinds with a 100 grain 6.5 main part 2-300 yeards some big ones , everything went perfect . Shot a few with 270 they died just the same with 130 copper factory and seen more done . No great difference really besidescnojse and recoil .
Problem with stuff like 243 ( something I shot for decades) is 1. The 100 grain rule 2. You should chose one like the Barnes not one of tge onces designed to fragment because that is going to limit penetrative. Barnescso far seem to pop out tge other side and if your not in thick ground cover you can often find an 8" say skid mark and the bullet sat in the end 100% weight retention only thingbis you sometimes loose a petal dropping that
Heavy for calibre copper will give std 243 win major stability / accuracy issues as length is tge stability factor not weight . Gonna need a faster twist barrel and of course those bullets won't be common
 
We have 6.5 lrx, 270ttsx, 30cal TTsX, 6mm lrx

Why though?
If supply is so bad at what point do you reconsider your options
They are also becoming ridiculously expensive

Is 270 going to end up being the most available in the UK in a factory available cartridge? Do you think?
My issue is of course any place that is factory ammo only being I use .260 rem

270 TTSX?
no chance
been waiting for Sako Powerhead 2 for months
Most oversubscribed cartridge and bullet choice

We do 260 rem in Fox Classic Hunter in 100 and 123gr
 
You’ve missed the point @Heym SR20. In lots of common cartridges, a normal 250m shot (not uncommon) with lead, is now a different proposition with copper. The .308 Win for example, especially the shorter barrels, will struggle to generate enough MV - and then maintain velocity to the point of impact - to give the same degree of confidence as a soft lead hunting bullet. That’s what our OP is saying about his current rifle and his discomfort with impact velocities below his confidence threshold.

Our tests were for our conditions. Doesn’t mean to say the logic doesn’t stand for lower ranges and other peoples’ requirements. I won’t accept terminal velocity of less than 2,400 ft./sec for copper bullets, which in my .308 Win means I’m forced to accept well over 100m less in effective range. And getting closer isn’t an option!

So the compromise was simply to use a more powerful cartridge. Problem solved.

I grew up shooting .270
130gr with claimed MV of 3150
When tested in a 22” it was closer to 3000
When shot in a 20” as is the norm now it was closer to 2850-2900

I now shoot .308
20” tikka, nothing fancy
136gr peregrine over 44gr of N133 is doing a genuine 2900-2950fps
Thats a .270 with a wider frontal profile by anyone’s description
I have shot them out to 495yds on vermin (crow), accuracy potential is there
I have shot deer to over 300-325yds
Colleagues shooting 124gr 6.5 out further.
Terminal effect is there.
They expand well, they exit, deer fall over.
The internal profile to the tip has a radial convex radial taper going into the meplat.
This initites expansion very quickly, as i found when i dropped one right on the tip

I wouldnt push a .308 or 6.5 on large deer beyond 400 as with any bullet type i am just not comfortable with the terminal energy and margin of error should the placement be slightly off.
You are also testing the expansion capabilities of any bullet should you miss a bone on the way in.
Seen it. It happens.

Have a 300 Norma for anything that requires a bit more thump

Stand at a mile and then tell me a 308 or 6.5 doesn't have the energy... 🤦 The 308 has been killing humans out to silly ranges for years, it's more than capable of taking a deer down at a few hundred yards. My 6.5 is apparently holding 1180 foot pounds of energy at 400, it takes sub 100 to kill a deer?

Oh they will kill
But with very little or no margin for error

With all the best internet bull**** in the world field group size at 400-500m is significantly larger than moa in 99% of the real world shots. (Not nice firm, flat firing point with no wind at fixed distance)
First round placement is the ONLY shot that matters.

Shoot a deer with a subsonic 22lr in the chest if you are so confident that it will kill cleanly and quickly.

Foot pounds is not the only consideration
Bullet type and construction is.
What expands well without frangibility at 200 may not at 400
What penetrates at 200 may not do so well when at 2000fps on a variable density target
Significant difference in skin and bone thickness from one species to another.

Am sure a .308 in the right hands on the right day from the right firing point will kill anything on the planet.
However we owe it to our quarry to gun up for the days it’s not right.
I won’t shoot past 350-400 on large species with a .308 unless I absolutely have to (wounded, injured, runner, fox etc!)

I have a better cartridge for that job

30-06 168gr TTSX at 2840fps works on fallow out to 350 no problem

People just need to just read a little and then select a bullet and go use it for there self

All this targe shooting and gel testing only gives you so much I was told you have to drive barnes light for calibre and fast that’s all rubbish

In " have to" you are correct ! However impact speed changes the terminal performance of a bullet in terms of expansion, faster it impacts the better the result! With lead and a frangible varmint type bullet on larger quarry you really can hit too fast and really limit penatration to the vitals . At extreame range However such a bullet can be a good choice as it's impact velocity slows .
Personally I have been using 6.5mm Barnes ttsx 100 grain it's expansion diminishes some when you leave 300 yards but up to that point is seems similar from say 100 - 300 . I have only so far experienced one failure to exit and tgat was a double shoulder shot , unfortunately one of a few brought in that day the opposite side showed a reasonable exit the the bullet had stopped inside.
Funny thing is most my spent bullet collection comes from the ground behing and is found at the end of a small scar in the ground . It appears after penetrative though they have very little left and they al, look like they same 100 grain copper
palm tree not a squished mushroom like lead looks like with substantial weight loss .
Cartridge .260 rem not a big boomer !
It's really been surprising how these bullets perform ,
 
If your reading ability mirrors that of your sentence structure and punctuation, I worry...
These are the entry middle and exit of a 250 yard shot and I have seen the same at 350 maybe the 168gr ttsx performance is slightly different to others

When I was using the 80gr in ttsx I never done the speed of them when I did they was only doing 2800 fps so was not even deer legal so I had to adjust load to get them up to 3200 but before I knew this they killed 100s of deer including big lowland reds so that proved to me that the speed was not every thing

It was interesting to re read back through this thread 2 years on. Thought it would interesting to update.

I’m still using 6.5 and recently had a trip to Scotland during the rut. 3 stags shot but none at range. Used factory Sako blade 120gr. Max range was 150y. All performed well.

If I can get these driving at 2850fps or faster through my 20” barrel, I’ll likely give them a try. If I can get the heads.
 
I am very satisfied with the performance of hornady Superformance International 140 grains in my 7x64 and Sako Powerhead II 110 grains for my .270.
