Brass for old cartridges

Does anyone know where I can get modern brass for the .43 mauser, the 8mm Kropatschek & the 11mm Gras?

I would appreciate any help from members.

Try contacting Elwood Epps. If that doesn't work, go to the Buffalo Arms website in the USA. They ship unloaded brass to Canada.

Try a company called Grafs in the US.

Grafs won't export directly to Canadians. They are owned by Hornady, I believe, but are distributed through different channels. Buffalo Arms distributes them, as does ebay seller "mrnambu". Epps deals mostly in Norma, Fiochi and Lapua, which will be pricier.

You can make Krop brass from 348 win cases

I tried forming 8mm Krop from .348. It was very tough. Any hints?

Annealing the brass makes it more pliable

If you need it really soft, heath the case neck till it turns red and then let it air cool. It will be very soft now.

Form the case, trim, etc.

Now re-heat the case neck till it's red and then drop it in a bucket of water while still red hot. This will anneal the case to the proper hardness.

Alot of work, perhaps, but if you have trouble forming the cases, it will help.

Claven, I've read of a procedure where the neck is heated while the base of the case sits in water. What kind of effect would this have on the brass? Would the brass then require hardening afterwards, as in your example?

No, that method is to somewhat soften brass after full length sizing it - it's called water quench annealing. Once they heat up to red hot you tip them over into the water to quench them. this wont; help sizing much.

if you let it air cool the brass will be at its softest with no temper. After sizing then you can water quench anneal to make it a bit harder, but still soft enough not to split, etc.
