17 Ackley Hornet

What's the preferred brass to use forming the 17 Ackey Hornet

 

[chester999]

PPU the last Winchester I bought just crushed, too soft. The PPU formed great, but I had to anneal before fire forming.

I've always used Winchester in the past, but the last time I used Hornady because its all I could get. Its "ok".

Even annealing, Ive had a lot of split necks with Winchester brass

 

[Mark M.]

The first time forming I used new Winchester brass, even with a aneeling, I lost about 20% to cracks. I was able to pick up from an estate, some new old stock Winchester. Super x brass, did the same process as the newer Winchester brass, Only this time I didn't lose any, not one of them. The old super it works great. I was able to pick up 350 brand new old stock Winchester, super for a 100.

In the old dated way we made cases at lake city there were 3 furnaces and 2 anneals in the process. So it might be a little brittle or a little soft. Made our length to shoulder vary down on taper. Doug
