Home Forums Hunting & Shooting Ask The Gunwriters 6.5-270 = 6.5-06 = 6,5x64 Brenneke ?

I was with you War Eagle. The first thing I thought a 6.5X64mm Brenneke would be was a 9.3x64mm Brenneke necked down to 6.5mm. That would be a whole different animal from a 6.5/06.

6,5x64 is an 8x64 necked down, but the 9,3x64 and 8x64 do not come from the same case. The are both 64mm long but the 9,3 being "fatter", resulting in more powder capacity, close to that of any of the 2.5" magnums.

6.5x270 == 6.5x64 Brenneke
6.5x'06 is shorter necked , same shoulder

6.5x280AI aka 6.5 BlowHole Express !
( see DogZapper / Eastman ? )

The thing is that 200 fps gain from the 6.5x55 to the 6.5-06 doesn't seem to make much difference in the field IMHO.

Every once in a while, we glean a nugget of true wisdom!

I would think that would be true in most hunting situations. At long range,however, the extra velocity is appreciated.

How about the 6.5-257 Weatherby ? LOL

Wouldn't a 6.5-257 Wby. be pretty close to a .264 Win Mag?

Just to complicate a bit:

Brenneke the man or the company was not involved in the design of this caliber which was an idea of Kepplinger, austrian gun maker. If was made to be a sort of standardised 6,5-270 and the Brenneke name was choosen (with right to do given by Brenneke company)for commercial reasons.
Brenneke Gmbh in Germany don't even produce bullets or cartridges in 6,5 caliber at the moment i write.

MFS hungarian company produce one loading of 6,5x64.

Note that, case dimensions are close to the 270 and different from the real CIP 7x64 or 8x64 dimensions at the head and rim.

In Europe the 6,5x64 is not well known and not chambered as a standard. The 6,5x65 and 6,5x65R are more often found.

The 6,5x63Messner is a french wildcat, today CIP approved, developped on the 9,3x64 case. It's really a magnum with performance very close to 6,5x68 or 264 Winchester with lighter bullets. It is generally loaded with monometal bullets (french or german) and it's effectiveness is proofed on numerous heads of game. Even african plain's game.

For the "little story" i prefer to load the 264, cases are much less expansives.

Dom

Dom, do you know if 6,5-06 is CIP approved?
I want to have a rifle done in the US but I will only be able to import it into Spain if it is a CIP cartridge...
If it is not, I would have it chambered for the 6,5-270 and marked as 6,5x64 Brenneke, hence my asking...
Merci.
BBerg

Hi BBerg,

After looking about CIP approved cartridges from the french proof house documents, the 6,5-06 is not approved.
Normal for a wilcat. Better go the the 6,5-270 aka 6,5-64 Brenneke which is CIP. Or even better for cases availability 6,5x65...

All the discution about neck length, shoulder angle and comparing 6,5-06, 6,5x65, 6,5x64 and 6,5-270 makes me laugh a lot...In the real world of hunting cartridges and handloading they are peas in the pod...

Any animal shoot by one or another cartridge will not come back to life to say the one which is better or worse.

Good choice

Dom

Out of curiosity, Dom, years back I had a K77 kipplauf in 6,5x65R and it would not close on a fully resized brass that had only been fired once and in that same barrel.

I believe the design of that large case with such a short neck had something to do with a dough nut forming in the inside of the junction of the neck and shoulder, which was the origin of the problem.

I had exactly the same problem with a 6x62R Fr�res, also a case with a short neck, but have never experienced anything like that with other longer necked cases I have worked with: 5,6x50R, 6,5x57R, and 7x65R.

I have some hate for cases with that design since then, and even though the much stronger camming action of a bolt action should avoid problems of this kind, therefore my decision of by passing it in favour of the 6,5-270 aka 6,5x64.

On the other hand, I will have the rifle made in America, and the 'smith migh not even have a 6,5x65RWS reamer...

I have noticed a French atelier d'armurerie, http://www.armeca.fr/latelier/index.html , that chambers for the 6,5-06... Can you take a rifle chambered for a wildcat to the official proof house in France?

BBerg

Hi BBerg,

I know well the boss of Armeca. Its job is really first class. He's a long range target shooter, a very good one, who prepare long range rig.
If he build you a rifle it will be very well done. And for sure for safety and insurance reasons the rifle will be proof tested at St Etienne proof house with cartridges of the caliber.

For hunting rig you can also look at my friend shop Dorleac & Dorleac. Use to work a lot with spanish cause he's close to the border (Perpignan is one hour and half from Barcelona). He is a real master in the ultralight mountain rifles (with match grade accuracy) and can build any traditionnal hunting rifle (continental, british or american taste)
Just google Dorlea & Dorleac. He speaks english and spanish too.

regards

Dom

PS: three pictures of D&D work

Caliber 6,5-284 in totaly squared and blueprinted ZB47 receiver, Leica 2,5-10x42



This light mountain rifle feed flawlessly the 6mmNorma BR with 105/107/115grs bullets. Weight scoped loaded less tha,n 3kg..


This one is made with workshop lefftover...! Seven receiver modified, 24inches semi weight barrel in 6XC for 105 to 115 bullets. Weight with the Swaro scope and 3 rounds is 3,370kg a bit less than 7,5lbs

Sure, I know Dorleac...!
I read about his rifles years ago in a very well know book, written by a French hunter, I can't remember his name, about chamois and isard hunting... I explored his operation but finally it was a bit pricey for me and ordered a Rifles Inc. from Lex Webernick instead.
Everything about Dorleac's mountain rifled looked excellent to me, except one small detail, which was the funny ubication of the safety, insider the trigger guard.

Sure for handloading 6,5x64 is better than 65 but why do you fully resize them?
Neck only will do without problem for three to five firing (may be more) if you shoot them in the same rifle and if chamber is tight.
I never add problem with other short necked cases too, like 300 Savage or 300Winch mag. May the RWS brass on this cases is a bit thicker and tougher, don't know for sure i'm not close to my bench.
Friend of me loading for 6x62Freres don't have problem with them, too.

Dom

Have you shot 300 Savage or 300 Win Mak. in a K77 Blaser break open single shot?
If you had you would have had to full length resize, I am afraid.
A bolt action, is quite a different thing!
Alvaro

Hi Alvaro,

Most of Dorleac rifles have standard safety but the guy love to experiment different ways...
Here one of the first he made, this one is mine for ten years now,was its own i bought it use, just changed barrel, caliber 7Rem mag. Know by my friends as the "Black Widow"...Had killed a lot.



About your problem, looks like all rifles are not the same as my friend and most guy i know with single shot K95 don't have real problem neck or partial (not the same) sizing only their 6x62R.

But for sure they don't reload their cases often, being hunting rifles only they don't use them target shooting except for some zeroing and control before hunting season.

They handload only because of 6x62R factory loading scarcity. Your right for 300Sav and Win Mag; bolt are different affair than SS...

Have good weekend.
Dom
