Anyone loading 7x64 Brenneke?

[c1a1]

Just bought a Zavasta chambered in 7x64 Brenekke. Looking for any info on hunting rounds. H-4350 and H-4831 seem like ideal powders using 150- 160 gr. bullets. Thanks in advance for any info.

When I loaded it, I used the data for the .280 Remington. The Speer manual stated in bold lettering that the .280 Remington data can be used for the 7x64 Brenneke.

I have a stainless Zastava M70, 7x64 does have less case capacity then 280rem, I use 280 data less 2gr as my max.
I settled on IMR-4831 for my powder, with 160gr-175gr pills. These have quite a fast twist (1-8.33) so the longer bullets work well.

I have a stainless Zastava as well. IMR 4831 and 150 gr Sierra bullets group into 5/8 to 3/4 inch @ 100yds(3 shots). Never tried anything else in this rifle. As already mentioned case capacity of the 7x64 is slightly smaller that the 280, so max loads for the 7x64 will be 2 or 3 grains less than the 280 handle.

I load for a Ruger M77 MKII 7X64 and a CZ 550 7X64... both loaded with 154 SP's and 58.0 grains of RL-22... it is a quick and accurate load.

I use 160 gr bullets and RL22 in mine. 280 data works fine. - dan
