Hi, new to the forum. Was wondering if anyone has been loading for 7x64 (7mm Brenneke)?
Any ideas on powder? I'm thinking ar2209, and 160-162gr projectiles, but open to suggestions.
Also anyone had any experience forming cases from other calibers?
Cheers
Cheers tobes, unfortunately I am still working through the 100 factory Norma I bought so haven't even started to look at handloads yet.
The person to ask would be @Hendrik470
Workshop innovation have brass
Hope ebf doesn't turn up mate he will give you a towelling for asking abouit loads on the internet :huh:
Welcome to the forum.
AR2213sc would be a good one for the 160gn pills.
Thanks guys. Generally I wouldn't ask for loads on the internet, but load data for this doesn't seem too common. Even if anyone can point to a manual with good data, that would help. I have the norma data but the powders are a bit obscure / loads seem a bit anemic.
I did wonder about 2213, but no experience with it.
Thanks for the welcome!
You can use data for the 280 Rem as it is virtually identical. I have done this in the past with pleasing results.
Nick Harvey did a big article on the calibre a few years ago. I can dig it out and send it to you if you wish as it has heaps of information and loading data. Just use 280 data as it is basically the same.

2213Sc would be my first choice as well, also I wonder about R19 as well? Need to check with someone to verify with that powder/weight and also note R19 can be very temp sensitive. VERY. Fast and accurate in a 280Ai but easy to run too hot in warm weather. Be careful, Obviously. [emoji362]
Didn't know that existed. Would be very keen if you could get it to me somehow. Obviously Im new here so if you can ket me know the best way that would be great.Quote:

Vihta Vuori, manual. 4th edition.
160gr partition, powder N560 min -51 gr,(2516fps) Max 56gr (2759)
N165 Min - 52.3 (2441fps) Max 55.5 ( 2769)
160 gr Lapua Naturalis N160 min- 40.9 (2339) Max 48.8 (2559)
N560 Min - 49.4 (2441) Max 53.2 (2677)
Thanks very much! Appreciate it.
Welcome @7x64
Start with the 280 loads and work from there, as mentioned they are virtually identical.
I've used both 2209 and 2217 in mine (currently shooting 140 SSTs out of my Steyr)
As others have stated 280 loads are fine as starting point. I have tried various powders/loads from 2209, 2213sc, RL19 and 2215 on 140 gn AB's, 150 gn partitions & 154 SST's.
2217 gave me best results & accuracy but I'm still chasing more fps for my 30 yr old HEYM. Love the calibre
Thanks guys, I have a Steyr, with a barrel a shade under 24". Sounds like 2217 might be worth a look...
Will likely play with 140s at some point, although results with factory 162s look promising for now.
Also currently needs a new scope. That might be an even harder question! :D
No this isn't a hack but I'm back in hospital (bored) and thought I'd revive said thread.Quote:

Yes to both. It's shooting well with 2217, but a bit on the slow side. Good mild-ish load so certainly more than usable. Basically can't get enough in the case, it's about as compressed as I am comfortable with. I will try 4831 as I have a stack of it...
Gidday Danny - hope you escape the clutches of the medco's soon with a good outcome !!
My CZ 7x64 (recently re-acquired from Norwest) likes 162 Amax's with AR2209, I took it up to 2900 fps but it was "happy" with exceptional groups at 53.8 (of the AR2209) which gave a 2824 fps avg. Norwest got it grouping like a benchrest rifle (like in the 0.1s/0.2s) with Sierra 150's and Win 760 (he's never told me how much, I'll pull one and see).
My 7x64 is now my "heavy thumper" and since it shoots so well its got the best scope I have on it (Leupold VX 5HD).
Cheers

How long's your barrel and how are the cases holding up? That's about what Hornady claim for their factory ammo, but I'm slightly sceptical as with what's written on most boxes...Quote:

Thanks again
Hello all
My barrel is 24". I did a wee comparison on Quickload for Norwest that's relevant here . . . with the 7mm Saum at Rem 7 mag length and using 150gn projectiles you have 64.2 grains H2O USABLE capacity, compared with the 284 at 55.2 and the 7x64 at 60.3 (at its normal mag length)
So it puts it in perspective a bit with a couple of the "fashionable" 7mm's
Cheers
The rifle Tentman has is an exceptional shooter, has good DNA it shot everything well. 54 grains of W760 with the 150 grain Sierra gameking was really good.
