I hope this new brass can be used to make

loads for the rifle that I recently acquired.

Does anyone know the answer for sure?

Jack:

Yes, it can. I did the same for 3" in the old days. Better to buy what .450/.400 3 1/4" brass you can find for now, and wait...

Find out the RIM Thickness and this will
answer your question.

If they stick to "thin rim" brass, then yes,
it should be able to.

Nigel:

They're going to offer .450 3 1/4" Nitro Express ammunition, and are making their own brass and bullets. It's .042" rim, so it will work for forming .450/.400 3 1/4" cases.

400

Thanks

That's good to hear - at least brass will be available for quite a while then, even if it's used 450.

Will probably give a resurgence to the 450/400 3 1/4" as well - which is good.

Yeah, it's nothing but good news.

Jack,

Some old experience here: I acquired a Jefferey 450/400 3 inch in South Africa in 1983 or 1984 and bought Bell 450 3-1/4 base brass cases to form. Needed a set of form dies and had to do some neck reaming (all very instructive to someone like me who had never taken a shop course).

With respect to earlier postings, suggest someone who can speak with authority advise you. Recommend you call Huntingtons and ask them. Or maybe call Hornady.

Regards, Tim

Thanks Men,

As an aside, I thought the 450/400 3 inch

Jeffery had a rim thickness of .060 and

the older 450/400 3 1/4 inch had a rim

thickness of .042. Are these #'s correct?

Ye, that's my understanding of it.

Hi Nigel,

"Nowadays" I work many overnight shifts, so I am up

at times that I used to be asleep and vice versa!

Jack:

No, .450/.400 3" has an .065" max rim.

The .450 3 1/4" and the .450/.400 3 1/4" both have an .042" max rim. So, you can form the 3 1/4" .400 from standard .450 NE brass. Yes, you do need forming dies. Don't try it with a standard die as the neck will collapse.

I made .450/.400 3" from BELL .065" rim .450 3 1/4" Basic. I don't know what other cartridges were formed from the thick rim .450 Basic (maybe .360 No. 2), but Bell, Sr. did make it, as well as thin rim .450 Basic. I still have 40 unformed rounds of the thick rim left.
