9.3 Brenneke

[sambarhunter]

Hey members,I have decided to build or hope to have built a 9.3x64 on a mod 70 action (pre or post) and was wondering as to action /mag lengths. I know the 375 H+H is long enough but the OAL of the 9.3 and the 300 Win mag are much the same.
Question what action/calibre will suffice for the 9.3 build?
If the 300 will do I may use one of my 300s..
I also have a TRG-S in 300 that is a great action,any ideas please guru`s?

You'll need a 30-06 bolt face to open up. The magnum .532 is too big. Brenneke has an odd rim

Yep, need a 30-06 bolt face to open to fit the 9.3x64.

I also am planning a 9.3x64 to compliment my 9.3x62. I will use a M98 action as the 9.3x64 was designed for a standard length M98. So a M70 will work also. I already have the action and a barrel, a 29 inch, and I will build the rifle in the "Cape Rifle" style. with open sights.

Ordering the chamber reamer today.

Hornady has good load data in their latest manual.

I have now just measured the detachable magazine box on my .300 Win mag Sako TRG-S rifle. Internal length is 95mm which should suit the `64 Brenneke`s oal of 85.60.

Would this be a suitable donor rifle/action? It is a very strong robust action and is the same action as the TRG`s with the being the 'ess' the sporting action.

Does anyone have any qualms about using this action?

I like the idea of using a Mauser 98 or Win Model 70. But this isn't my rifle.

The rifle was built on a `98 eventually and has been in the field and knocked over a few deer,even a cat and a fox too in its infancy.

you will come to love it as you learn the best bullets and loads for the jobs you do.
i never regret my journey learning with it, apart from going up a blind alley with nosler partitions.

Funny thing.... I have an elder friend with a pre-64 in 9.3x64, we THINK this is a factory chamber out of the custom shop but can find no supporting evidence.

Next step is to take the stock off and look at stamping on the underside of barrel; but with health concerns that is going to have to wait until after COVID.

That would really be neat. Please follow up when you figure it out.

I am fairly certain that there were some chamberings from Winchester...I would love to own that one.
