.264 Win Mag

[bosveldjag]

I am in the process of having a tailor made .264 Win Mag manufactured in South Africa by Truvelo for specific use on long distance shots on springbuck, blesbuck and swartwildebeest - all plains game, lots of open spaces and little bush coverage.
Some of the specifications are: 1:9" twist and a 27" barrel length.

Anybody used this type of rifle successfully under similar hunting conditions?
More detail on bullet types, loads, etc. would also be appreciated.

Can't help with your question, but I do want to welcome you to HuntChat.

Come to think of it, maybe I can help a bit.

With that twist rate, I'd guess that you'll be well served with bullets in the 140-gr range. Powder choice is easy: IMR7828 was the powder in original factory loads, and it's still a good choice. The new Short Cut version of 7828 may be even better.

Other super-slow powders that should work well are Retumbo, Big Boy, AA 8700 and RL25. Norma MRP also fills the bill if you can find any.

HELLO

NOT TO CONFUSE THE SUBJECT BUT IF IT WERE ME I THINK I WOULD BUILD A 6,5X68. IT'S AN OLD CARTRIDGE AND WITH MODERN POWDERS I THINK IT WOULD BLOW THE DOORS OFF A 264 WIN MAG.

IV'E HEARD IT'S USED EXTENSIVELY IN EUROPE SO COMPONENTS SHOULD BE AVAILABLE.

JUST A THOUGHT.

[bosveldjag]

Thanks Bill, but the idea is here to have a gun made with which one can shoot accurately over long distances - up to 600 meters and more is the norm for the plain's game mentioned.

By using a premium type of bullet one certainly doesn't want to

BLOW THE DOORS OFF

.
My motto is to kill the hunted animal as effectively as possible with the minimum meat damage.

[Rocky Raab]

Hey bos,

enlighten us a bit on your (I think) Afrikaans screen name. I can deduce that the "veldjag" part means "plains hunt" but what does the "bos" mean? Something like chief or head?

So the screen name would mean "Head plains hunter"?

Or am I completely off the mark?

I have finally got a load,thanks to John Barness.I used his Handloader article as a starting point.Understand my rifle chambering is different than his factory Westerner,more throat.So I will not give how many grains I used,these rifles can be tricky enough.This is my second barrel,a Douglas, on this '68 FN ,it was a NIB.The first barrel,the FN, walked and was all lands,too high a friction barrel for a touchy cartridge.

The bullet I used was 140 SST,a boat-tail,for less barrel friction.In .308 180gr they have been very accurate for me.

H-1000,my lot acted more like H-4831 with the FN barrel,it spiked and popped a primer at the starting load,even at lower loading it wasn't as consistant as IMR-7828 .

N-560,nice and consistant in the walking barrel,targets could be layed on top of each other.With the second barrel velocity topped out at 3050,next loading of one more grain 3050.I thought I better try something else.

IMR-7828 give the velocity,but not enough accuracy for a long range rifle.

Rl-25,I got the velocity (3150) but it didn't group And each shot went faster in the groups,likely from barrel heat.

Retumbo at 3150 it didn't group,and it seemed a bit high on pressure.My primer radius was a little less.Both Mag-Pro and Ramshot Magnum were more promising.

Mag-Pro,I got the velocity and the second best groupings.It may work for you.With my lots of powders,it was one grain faster than Ramshot Magnum.

Ramshot Magnum,I got 3200,half rounded primers,and under MOA with two touching.What more could you ask for.It was sure hard to find Ramshot Magnum in Canada.Rayner-Shine had it at the Kamloops gunshow.

I hope this helps other 264 club members.

To: Rocky -
'Bosveldjag' is actually a combination of two standalone entities to create a new word with a different meaning!
I.e. 'bosveld' = 'bushveld' which is a typical lowveld area in South Africa covered by many types of indegenous trees, shrubs and grasses.
Then 'jag' = 'hunt'.
Put together results in 'bosveldjag' meaning therefor a hunt in a bushy area called locally bushveld. ('veld' = plains or open area in the wild where animals roam freely.)
Sorry for this lengthy explanation, but I'm not a language expert at all!

The obvious question would now be: 'Why a .264 Win Mag if the hunt is taking place in a bushy area?'
In SA we also have open, grassy plains where very little or no bush coverage is available and that is where the mentioned species roam leading to the need for a long distance rifle for relatively small to medium type of game.

To: Downwindtracker2 -

Thanks for the info, I will later report on what I am planning to use on loadings and bullet type.

[Rocky Raab]

Hmm, I was closer than I thought.

I'm a student of language (a darn poor one!) and simply love etymology. Thanks.

ps, I forgot this in my earlier post: Ramshot renamed their Big Boy powder "Magnum" because there was confusion with their other powder called Big Game. Magnum is the one for the 264 - if you can get it in RSA>

[Downwindtracker2]

I doubt Handloader is easy to find in SA.And his posts to the 264 cult.So I will recap Johns choice of 140 bullets and it's use. He likes Speer,so he used their 140 in his tests and hunting. He shot a couple of deer with it,one under a 100m ,the other at 250m.Both times the bullet exited with a exit wound the size of a "silver dollar" with very little meat damage.

I have the Winchester handout when the 264 was introduced.It was designed around the 140.They felt the long range performace of the 140 made it the best choice.

I had such bad time with the FN barrel,I choose a BT.

John Barness powder results are very similar to mine,he too chose Ramshot Magnum with Accurate Mag-Pro second.By the "Made in SA" on the bottom I think Mag-Pro is made by SoChem. Ramshot is a made in Belgium.

I use my 264 to hunt Mule deer in large logging clear-cuts.

looks to me like the 270wsm does all the 264 does without the fuss.

it was pretty good rifle for me and didnt take long to push 140gr slugs acuratly to above 3100fps might have been closer to 3200. i dont have chrony so i couldnt say for sure.

[bosveldjag]

I'm planning to use the following in this .264 Win Mag:

• Powder S365
• Start load in grains 59
• Max. load speed 3650

or

• Powder H4831
  Start load in grains 65
  Max. load speed 3650

These are SA powders ( don't know what US eqv. are)
(NB My re-loading friend helps me with the technical details on all this!)
Bullet type: 264095HV.134 (95gr solid)
BC .435 G5
Only Magnum primers are used with these loads.

It is a premium quality monolithic bullet manufactured in South Africa and used with great success worldwide.

im starting to form opions on caliber here that maybe dont go with your way of thinking, but there are alot of other standerd calibers that will fling 85-100gr bullets from 3400-3700 dependiong bullet weight and caliber.

even the standerd 06 case can shoot light bullets pretty good, the case is not belted and the action is smaller.

a 6mm/06 would fit the bill, even standerd 270win pushn 90gr bullets might get close to 3700fps the 2506 will come right to 3700 mark pushn 85 bullets and only lose about 200fps when loaded with 100gr bullets.

chances are the 270 2506 and even 3006 facotry ammo is pretty abundant over there.

im just not real hot on the 264 not when there are alot of other calibers that throw light bullets just as well. now if that thing was pushn 140s that fast then wed be talkin.

isnt the 264 a 6.5mm call???? im not positive

this is just my opion. im sure the 264 will turn out just the way you want it to.

My last client carried a 264 win mag. It was a stainless synthetic BDL with a 26" barrel. He killed a 33" Aoudad at 358 yards, shooting factory 140 grain core-lokt. It was a one shot kill that broke both shoulders and exited. I was very surprised how little the core-lokt opened up.

[bosveldjag]

isnt the 264 a 6.5mm call???? im not positive

Correct. So is the .270 the only geniune 7mm.
7mm rem Mag for instance is actually a .284 - thus actually a 7.026mm!

The .264 Win Mag has proved itself as being extremely accurate and also having deadly killing power.

I was just reading your post. I happen to be a 6.5 nut and have been since about 1960.

The 264 WM custom gun is an excellent choice for your needs and the bullet you selected should do just fine on the smaller, thin-skinned plains game. The barrel length at 27 inches should be fine, dead in the middle of 26 VS 28, either of which work well in a 264 WM. The only thing I would consider changing, were it my rifle, is the twist. The 1-9 twist is accurate, say .25 to .5 groups. However, in my experiance the real accurate twist, for a 6.5, down into sub .100 territory is the 1-8. The 8 twist will handle bullets from 85 grains up to and including the 160s, with ease. The 85-100 grain bullets should shoot sub .100 in the 1-8. Velocity into the 3500 - 3700 range is also no problem for the 1-8 twist.

I would also consider the barrel be made in a stainless, heavy sporter or magnum sporter, fluted. The combination will give you medium weight, stiffness and surface area for cooling. The case capacity, caliber combination, will get a barrel hot quick. The stainless will resist erosion about as well as you can expect.

If you still do not have the barrel selected, I would suggest a Lothar Walther stainless, magnum sporter, computer lapped, match barrel. I have used this same barrel on my last dozen rifles and really like them.
Good Luck with your rifle.
