Charlie64Thoughts 9,3 x64 Brenneke vs .375 H&H
.
Looking at a 9,3 x 64 Brenneke rifle and researching a bit on the round it looks like it has pretty much the same velocity and energy as the .375 H&H, based on what I am reading and hearing. Bullet weights off the shelf go to 293 grains and speaking to one or two who shoot and reload the 9,3, they say that there is room to push it a bit faster if you want to.
Anyone hunted with one in Africa at all or North America ?
And before anyone says `buy a .375`, I have a couple already. Just interested in something new perhaps!

MJinesI used a 9.3x64 Brenneke (made by Brenneke to boot) on my hunt in Burkina Faso. Shot a savanna buffalo, roan and a reedbuck with it. Performed very well. I think it gives up nothing to the .375 in terms of performance in the field. I did not do a lot of playing around with the round from a reloading perspective so I am sure with today's powders more performance can be squeezed out of it.
I am pretty sure Forrest Bruch used a 9.3x64 on one of his hunts too, maybe to Burkina. Forrest was so impressed he declared that he was finished with his 9.3x62 and was a full Brenneke convert.

wildmansixI shoot the 9.3x62 and x74 quite alot. When I was researching the 9.3 years ago I also looked at the x64 and x66(370 Sako) with modern powders and loading both the x62 and x64 to the same pressure levels. The x64 was about 75-125 fps faster. It's shortfall in my book was the logistics of the round. Ammo and Brass were very tough to source and cost 2-3 times what the x62 costs were and you can get X62 brass and ammo very easily
When compared to the 375, The ballistics were almost the same but back to the logistics. 375 is everywhere.
If you are looking for something different the x64 will work well. However I would source a lifetime of brass and a set of dies before I bought or built the rifle.

Factory rounds & brass are plentiful in Europe. Not an issue at all.
I can see it being an issue in Africa if the ammunition does not turn up on arrival, then it would need to be plan B the PH rifle ....
Mike, Have you still got the Brenneke 64 ? What year was it ? Must have been a super interesting piece.

AtkinsonAs good or better than a 375 H&H ballistically but the Holand is better choice for the average hunter suppose,,

jeffeossowell, we make 9,3x64 brass by turning off the belt and rim of 375 hh cases, size and trim - so right on the heels, or in it's tracks
DO NOT be confused the with x62, which is a .473 case

Mike, What a stunner! Looks as if it is pretty original all around. Between 1951 and 1971, which was when Brenneke (the company) moved out of Berlin. Would have to research the proofs to get the exact date obviously.
Great looking rifle. Personally I would have put a period German scope on it but thats just me, nothing wrong with a modern Leupold!
Thanks for sharing Mike. A super 9,3x64.
And a great looking tiger fish on the wall too!!
Cheers
Charlie
