Brno 7x64 & Hornady 162gn ELDX

[Spongebob]

Good Evening All

I am looking to start load development on my Brno ZKK600 7x64B. Most of the R&D done through various powder manufacturers and online resources point me to a 160gn Nosler Partition.

These are not easy to find in South Africa and the next best alternative of which there is an abundance of stock is the Hornady ELDX. I am a Hornady fan so the decision isn’t very difficult given their new drag technology etc.

I wanted to hear the opinion of others and see if anyone has a point of departure for this load combination.

Hi,

For some years I had a beatuful Mannlicher-Schoenauer GK long rifle in 7x64. And developed many loads for 160 and 175 grs bullets. After a lot of work, I arrived at the same RWS loads. No too much to improve:
160 grs = 58 grs R22 (same powder as Rottweil R905 and NORMA MRP) for 2850 f/s
175 grs = 56 grs R22 (same as above) for 2700 f/s
I did not try R25 (NORMA MRP2) but if one is after the best relation of velocity/pressure with 175 grs I would put a coin on it!
Another good powder I tried was the IMR 7828 with 2 grs more than the R22 for the same results.

Good luck!

I have just purchased a 7x64 from a South African living in Australia.
He has been using Hornady ELD-X over a load of AR2213 which is H4831sc

Thanks Clodo
Definitely aligned with the bullet weight, our powder selection varies in South Africa but will have a look at the burn rate chart. Thanks for sharing.
