Home Forums Reloading Big Game Rifles 7x64 Brenneke

Beautiful. Are those EAW pivot mounts?
I am thinking of putting those on 2 Remington 700s I have with iron sights, one in .270 and the other in .30-06.

What is your best load for the 7x64?
I am thinking the Hornady 154-gr bullets have to be tried right after the 140-gr CoreLokt.

Correct Lee, both are EAW swing-out mounts. I've had several in years gone by and always was 100% satisfied. Expensive but true work of arts and with absolute return to zero (I've tried several cheaper brands but there's no comparison in terms of quality).

I found it easy to develop sub-MOA loads with 150 to 175 bullets (lighter bullets do not shoot as well in our 1-9" twist bbls.). Here are some loads I like (pls. use caution and start lower):
Sierra 150 GK / H 4350 / 54.0 = 5 in .65 MOA
Sierra 160 GK / N 160 / 56.0 = 5 in .41 MOA
Sierra 160 GKHP / same load / = 5 in .51 (same P.O.I.)
Hornady 175 BTSP / H 4350 / 52.5 = 5 in .39 MOA

NB.: CCI 250 primers are used with VV N160 powder. Other powders are lit with WLR.

My 7x64 being used mostly on Roedeer, the 160 GK has become my std. load. When expecting some bigger game, I'll switch to the same load + the harder 160 GK HP. So far, this same load has shot 26 Roedeer, 5 Red stags (with careful bullet placement), 1 Fallow deer, 2 Muntjacs and several foxes, all shot between 50 and 250 meters.

Thanks! My Brno carbine has a 9.5:1 rate of twist. My 7mm-08s love the 120 Nosler BT, any 140, and all the 154-gr bullets.
Having a soft and a firmer 160-gr bullet both shooting to the same POI is all you need.

How big are your Roe Deer?
I guess you have to use something like the 7x64 in France. What about Belgium - can you hunt with "military calibers" like the .30-06 there?

I own a SIG Sauer SHR970 in .308, so I know the accuracy you are getting is not all due to the loads. Mine shoots everything well. If I didn't already have some bad-weather all-business hunting rifles, I would have snapped up a 202 matte synthetic .270 with iron sight for $1,000 recently.

Roe is our smallest deer species, with a live weigh of 25-30 kg (55-65 lbs.). However, as is often the case with light animals, they can be surprisingly tough and if the 1st. shot doesn't kill them on the spot, you may be in for some blood tracking. This is why I insist on using "too heavy" calibers like 7x64 and .30-06 on them. The latter is becoming more popular in our hunting fields as it was only recently "demilitarized" (regarding military calibers, we used to have the same situation as in France). Red stag (Cervus Elaphus)is another beast however, a smaller (and genetically compatible) cousin of your Elk (Cervus Canadensis), they have a live weight of 180-250 kg (395-550 lbs.). I've shot some with my 7x64 but, if given the choice, I'll rather go to my .300 Win or 9,3x62. These 2 evidently hit harder and produce more bleeding, should tracking become necessary.
Your remark about the Sauer accuracy is right. Both my bbls. (7x64 & .30-06) shoot into 1 hole (the same might be said of the Blaser R93, of which I own 3). These 2 rifles are the only ones you expect to shoot sub MOA, right out of the box.

Andre,
What do you think of the Norma 170-gr Vulcan load?
How about the Sellier & Bellot 173-gr SP?

Here is another picture of my BRNO.

I happen to have mixed feelings about the 7x64 170 Norma Vulkan. Back in '96, I took my Sauer 202 to the Scottish Highlands, stalking Red Stag. I've had the rifle since a year and hadn't hunted with it yet, nor settled on a petload. Having tried the 170 Vulkan and found it very accurate for factory ammo (.5 MOA for 5 shots), that's what I took along. All went well and I cleanly took 4 stags at distances running between 150-200 m. Then came the 5th one, which dropped like a stone from a shoulder shot at 250 m, so far, so good. En route to the downed animal, the stalker and I were surprised to see the still distant stag get up and start trotting away from us. I didn't think, went prone and started shooting immediately (good I had reloaded my rifle before starting). The stag was now over 300 m now and trotting fast. Thanks to the very wet soil (peat) I watched the bullets splash and could adjust my forward hold. On my 3rd shot, we saw and heard the hit and the stag went down. I reloaded and we went for him. When near, I stayed behind a but to close in. When I looked over the top, I saw that the deer still had his head up and immediately shot him through the neck, dropping the head. Standing before him, we were amazed to see the eyes were still blinking. My stalker grabbed an antler and dropped his knees on the neck, finishing the animal with his knife. While gutting the stag, we noticed that the 1st bullet was a lung shot and the running shot entered just forward of the right hip, before exiting behind the opposing shoulder (after nearly complete penetration lengthwise !). No bones were hit and all 3 exit wounds (incl. the close by neck shot) were about pencil size ?!? Clearly the bullets did not expand properly and acted more like a FMJ. Oh yes, the 4 earlier stags all had broken shoulder(s) and expansion looked OK when viewed inside the carcass.

This being said, I know many hunters who praise the Vulkan. Maybe I fell upon a bad lot, go figure... In other circumstances, I've been pleased with the Vulkan 9,3x62 on Wild Boars (close distance running shots during drive hunts).

Regarding Sellier & Bellot, I've never found them accurate in my rifles (in different calibers) and may have developed some prejudice against them.

Thanks! I have had excellent results with the S&B .303 FMJ loads, and I can buy their 7x64mm ammo for just under $20.00 a box, so I have to give it a try for accuracy.

The 170-gr Vulcan bullet sounds like it is fairly tough, but who can figure. I shot a really big mule deer three times through the heart at almost 300 yards with a 150-gr Bronze Point from a .30-06 and none of them made a big exit wound. I just kept shooting until he stopped trotting.

I started my boys with 40.5 grains of H4895 behind a 125 grain Nosler Ballistic Tip, Remington cases and CCI 200 primers. The kids tell me it recoils about like a .243. This load has killed several antelope with no problems. Good Luck!

I like those rigs.
I know of a factory NEF handi rifle here in 7x64 Brenneke.
Strange, yes? But NEF did chamber a few handis, with 24-inch barrels, in the Brenneke.

Ruger made the M-77 MkII in 7x64 Brenneke, too.
I found a nice one recently for $600.00.

I bought one last month.on ruger forum they said they only made 371 in 7x64.
pete

If I didn't have the Mauser, I woiuld buy the 77 in a heartbeat.
Is it a 22-inch barrel?

I am shooting my Brenneke Stutzen -made about 1938 by Wilhelm Brenneke in Leibzig - since 1980. Until now I am using the RWS HMK 11,2g on roe, boar, red stags and fox quite successful but this year I will try the Sako Arrowhead II 150gr.Sometimes the HMK is a little bit too rough on a small roe and I hope I will get less haematomas with the Sako. If it does not work I'll try the 150 Sierra Gameking 150gr. Does anyone have an experience with the Sako (it is identical with the Sciroco Swift II)

CastnBlast,

Did you get a chance to shoot your Brno 7x64 yet?
I got rained out Saturday.

I have owned a couple of those lovely little Brnos in both the model 21 (rifle) and the 22 (manlicher)..I don't know of a better made rifle that ever existed and that includes custom rifles...
The 7x64 is simply a 280 Rem. balistically, and thats no bad deal any way you cut it....

Hi Lee24
Yes I did shoot my Brno 21H rifle last week. I did not purchase the Lyman 2.5 power scope that was in the picture, Instead I installed a Leupold 6x compact since I had on hand and it fit the original Brno mount and rings with room for the bolt handle.
I shot some Hornady 162 gr. SST loads, and they grouped very well, around an inch or so without any special care on my part. I also found a part box of old RWS 11.5 G ( 177 grain) TIG ammo at the Calgary gun show. Now I want more! It grouped into a nice cloverleaf on both targets.
I found a few bags of cheap Remington brass at Wholesale sports in Saskatoon -looked like old stock, and only $20.00/50! I worked up a load with Speer 160 grain Mag Tips, 54 grains of IMR4831 and Remington 9-1/2's - they did not show any excess pressure signs but I have not put them over the chronograph nor have I done any proper bench rest target shooting yet. This is going to be a fun and useful rifle!

I took my the Brno 21H 7x64 Brenneke out this evening for a bit of load development.

I found that the RWS 177 grain factory loads are loaded to full potential - 177 grains at 2708 fps.

My handloads of 54 grains of IMR 4831 over a 160 Speer at 2580 FPS looked anemic by comparison. ( new Remington case, Remington 9-1/2 primer) Groups were nice, less than 1"

The Noser 160 Accubond must give a bit more resistance, with the same powder charge they were a little faster at 2605fps. groups opened up, about 1-3/4"

Hornady factory loads with 162 gr. sst measured 2660fps.

Here is a recipe from Brenneke:
177-gr RWS TIG bullet
56.6-gr Norma MRP
Norma brass
RWS 5333 primer
2,800 fps from 24-inch barrel

Now, to just obtain the bullets!
But it should be one to try with 175-gt Hornady RN and other American bullets.

In my 22F carbine, it will probably end up being a 139-gr bullet over N-140, or 160-gr Speer HP or Nosler Partition over N-160 (58.0 max = 2,2890 fps from 24-inch barrel).

Makes me keep shopping for a bargain on a 22 to 23 inch rifle!

I shot the 22F with Norma ammo, 150-gr spitzer flat base at 2887 fps list, about 2800 from the Brno. Boy, this ammo is hot! had been shooting a .270 that weighed less than 7 lbs right before this, and the Brno, close to 9 lbs with its claw mounts and 2-7x Hensoldt scope, had much more noticeable recoil.
