.270 copper question

[jfr_1991]

A question for those more enlightened than myself.

I shoot a .270w. An unmoderated, iron sighted Charles Lancaster with QD scope. I’m currently feeding it a diet of RWS 96gr copper which according to the packaging run around 3500ft/s. These are grouping around 0.7 MOA so I’m quite happy with longer range shots requiring no real thought (should be perfect for an Austrian Chamois trip later this year).

However, I’d kind of like to turn it into a 7x57 by shooting a 150gr copper projectile around 2750ft/s. I’ve run some Hornady SP 150gr through it a few years ago and it was 0.4 MOA.

My question is, do people think I will get adequate expansion of a monolithic bullet trundling along at that sort of speed? Or am I going to pencil-hole beasts?

Sorry if this is ignorant of me, but some guidance would be appreciated before trying to find factory ammo or falling down the home loading rabbit hole.

Regards

Joe

Without a lot of knowledge, I only run 112.5gr Yew Tree in 270, why the desire to stretch the parameters ?

As with all things in life, a little bit of knowledge is a dangerous thing. I’ve read a few articles about heavy for calibre, slower moving rounds providing good stopping power with minimal carcass damage. Was thinking along those lines. All of my shots are within 150m so trajectory isn’t so much of a worry. I suspect I’m trying to reinvent the wheel and I should just have a 7x57 as well.

You may find that your barrel twist won’t be suitable for a 150 grn copper bullet (assuming you can find one) as it will be a very long bullet & need a fast twist.

As regards adequate expansion (of any bullet) - it’s the terminal velocity that matters - what’s the maximum range you’d shoot at?

Why not just do what I did and get a 7x57?

I loved the 270 but the calibre that relit the fore in me was the 7x57

That’s a fair point. I believe it’s the standard 1:10, so a 150 copper might be too long to comfortably stabilise?

I rarely shoot above 150m; I’m better at stalking than I am sniping.

I’m about to take £100 off a bloke who bet me 150gn copper wouldn’t stabilise in my 18” barrel 7x57

20 years ago when I first started shooting copper bullets (back then from cliffs gunsmithing in Utah) it was fly by the seat of your pants and make it work!

The key to loading copper is talk to those who actually know and ignore most of what you read on the subject on the SD

You don’t need a lot of speed if you select the right bullet. I’m using Sako factory in 130Gr out to 400M with no problems.
You also don’t need as much weight with copper, you will get far more penetration than you do with lead jacketed rounds. I suspect that your 150Gr bullets will penetrate like 170Gr lead.
I gave up on very high velocity, low bullet weight options decades ago, I found them very damaging with unreliable performance.
I’m now a convinced middle of the road convert, medium caliber, medium fast and middling heavy.

I'm using 95gr ttsx in my 270, MV 2900fps works fine for me. Range up to 250 yards deer size muntjac to fallow

The original question was about a 150 grn copper bullet in a .270, not a 7mm. My response didn’t mention barrel length which is irrelevant (within reason).

And what I’m saying is, it doesn’t matter what people say or believe, if you want it to be it will be, you just have to work at it and horlicks to the cost!

And like I also said speak to those who know and ignore most of what you read on the SD because most on the SD only know what somebody else has told them or they’ve read online not from experience!

I am very fortunate that I am speaking from experience

Are there any UK stockists?

Are there any UK stockists?

I have always used the barnes TTSX good, reliable and work!

I don’t, won’t and never will use the uk copper offerings, from the carcasses I’ve seen shot with them their just not for me.

Personally I would look towards reloading solutions, if you’re looking for factory ammunition couldn’t tell you where to start looking

Without naming names of brands , they kill really well and are accurate but the damage is just not acceptable.

I’m just sticking with Barnes and hasler.

Easy to source.

It depend on the shape of the bullet if you accept a 300m max range a roundnose flat base 150gr copper bullet works fine.

No you have to go through an importer.

 

[A Guy Out West]

Isn’t the classic deer load for a 7x57, a 140 gr. bullet? I believe Hornady makes a 140gr. Loading in .270. The old 140 gr. Light Magnum loads they once made were spectacular. I myself would go with a 110 gr. Barnes TTSX for the hunt you are going on. I know that there are a few on this sight that would agree.

Agree totally - having put a lot of work into the shooting of the beast, I like to get as much from the carcass as I can.

Using a bullet that splits up on impact causing further damage just doesn’t help my cause.

I’m using Barnes TSX in my .300 Winmag and I have a few left to load up (and I don’t shoot that much of that calibre)

And in my everyday rifles - 6.5x55 and .308, it’s Fox Classic Hunter in 124 and 150 grain.

 

[wytonpjs]

I myself would go with a 110 gr. Barnes TTSX for the hunt you are going on. I know that there are a few on this sight that would agree.

Exactly my round of choice in this calibre on fallow, using Vhit N135 doing 3134fps. Virtually all drop on the spot
