More thoughts on 9.3x64

[Zkk93]

Hello everyone,

Thanks for the replies.

I have loaded some 286 A-frames and hope to get to the range soon.

Also in my experience I haven't seen such a big difference between 62 and 64.
The main difference is that you can easily find a longer barrel in 64, the difference in velocity is 60 m/s for 286 grain bullets.
In my case with the A-Frame I would like to push the load up a few grains.

I am currently working on the Norma URP, any suggestions to increase velocity?


Antho9364, nice load, where do you get Degol bullets? What powder did you use?

Ballistically there are some differences between the cartridges 9,3x62 and 9,3x64, no matter what is written on the ammunition boxes or what is measured at the shooting range. I can report from practice. I used the cartridge 9,3x64 and the 19g TUG bullet in open areas, in the steppes and also in the high mountains of central Asia, for hunting heavy game species and shot some of them at longer range. Since I also have experience with the cartridge 9,3x74R which has similar external ballistics to the cartridge 9,3x62, I can hardly imagine that such shots at such distances would have been possible with the cartridge 9,3x62. The cartridge 9,3x62 has an aura in the circles of African hunters that unfortunately the 9,3x64 never achieved and that is primarily the reason for their reputation.

I spoke to David Bertram (Bruces son) today about the availabliity of 9.3X64Brenneke brass. He walked to their storage shed and confirmed that they have 4,000+ pieces in stock, that were left over from a contract they had. They are not stamped as B B (Bertram Brass) they have a German Co stamp on them? Guess I will find out which company soon, as I am placing a order for 100 pieces.

@BlueFlyer would be cool if you can find out which German company places orders at BB.

I should be able to show you next week, when they arrive.

Brass arrived today and it has the Bertram Brass headstamp.

I just listed some new HDS 9.3x64 brass in the classifieds.

I spent a hour after dinner tonight deburring and annealing the neck and shoulders on the 100 Bertam Brass cases. I cobbled up an induction annealing machine from watching a few Youtube videos. The 3 modules that make it up I bought off Aliexpress for about $100.

Before and after.

Bonjour tout le monde,

Merci pour les réponses.

J'ai chargé quelque 286 cadres A et j'espère arriver à la portée bientôt.

Aussi dans mon expérience, je n'ai pas vu une si grande différence entre 62 et 64.
La principale différence est que vous pouvez facilement trouver un canon plus long en 64, la différence de vitesse est de 60 m/s pour 286 balles de grain.
Dans mon cas avec le A-Frame, je voudrais pousser la charge sur quelques grains.

Je travaille actuellement sur la Norma URP, des suggestions pour augmenter la vitesse ?

I got Wim Degol's email on AH.
I contacted him and he was able to send me the warheads to France.
I used RS60 powder from Swiss Reload.

I suspect that you mean bullets i.e., not warheads !

Good morning,
I present to you the work done with a friend.
This is a load for the splendid 9.3x64mm Brenneke.
The bullet is a Degol Starkmantel RN in 320 gr, propelled at 735 m/s (Garmin chronograph) from a 65 cm barrel, with good grouping and more than 5600 joules.
The powder used is RS 60 (4.35 g) with a pressure of 4000 bar, and an LOA of 85.6 mm.
The weight retention is 90% which is very honorable and the penetration is greater than 286 gr.
Mr. Degol explained to me that this ball is harder than the Woodleigh 320 gr RN which is more suitable for the 9.3x62, 9.3x74r and 360 no2 NE.
Of course the Degol Vollmantel (FMJ) 320 gr is made to have the same trajectory as the RN, which makes it a remarkable duo.
In comparison to the 9.3x62 which became known around the world with its speed of 720-730 m/s with a 286 gr bullet and an SD of 0.305.
This 9.3x64 weighs 320 gr with a speed of 735 m/s and an SD of 0.341 and a better CB.
We have a little more speed with a much greater penetration and weight.
Be careful for Caffer Caffers

I have something similar with the 320gr PP SN from Woodleigh and 67gr R904. Unfortunately, these bullets are no longer available.
