Another 17 Hornet brass forming question.
I am trying to form 17 hornet brass from Remington 22 hornet brass. I am using a redding seater and full length die.
I am getting a fold or like dimple in the upper part of the case. I'm setting the seater without the plug just touching the shell holder, but backed it out about a half turn. The full length die i have adjusted to to just touch the shell holder. I have read the 22 page sticky here but I don't recall if anyone has had that problem. Just wondering what is the cause. |

I've had no luck with used Remington 22 H brass using a single pass. All crumple for me. New PPU with light lanolin in a FL Lee die works great for me.

For everything I did early on, I used privy brass also. It worked great.
No experience doing any forming with RP brass. -BCB

I've always.....
......sized the necks down in three stages.
I use the old "double-ended" die.....then the full-length die. Then fire-form cases with 7gr. Unique w/ paper towel wadding(no bullet). Many, many cases over the years.......and NO split necks or shoulders. Hope this helps. Kevin |

You are forming the case too much with the FL die or you aren't using enough lube. You are effectively crushing the case. After the 17 neck use the 17 FL die a full turn to turn and a half off the shell holder. If you are touching the shell holder you are likely engaging the crimp function in the die and that is likely what is collapsing the case as I presume the collapse is coming in the second step.

As Kevin commented. Obtain yourself a double ended sizing die, from Bullberry or other makers and do the sizing in three steps and you will have no issues with any brand of brass in making/sizing your cases.
But trim and anneal as needed for longer case life, also. |

Without a doubt , everyone needs a Bullberry double ended die. It cures lots of problems by making them non-problems....

Thank you guys for your responses.
I do have a 17 ackley hornet and had formed both Remington and Winchester brass, but it has been years since I had to form brass for it. I do recall I have the form and trim die. Just one question about annealing. How long are you guys holding a flame to the neck of the brass when annealing. I've never had to anneal for my 17 ackley hornet and I am on my fifth firing. I do understand this is a similar cartridge but different specs. |

You want the neck area to just start turning orange/red and then pull from flame and either drop on damp towel, water pan or air cool. Depending on what your prefer. |
