Case Forming
What are the steps in forming 6x284 from 6.5x284 Lapua brass? I am thinking about building a 6x284 custom rifle,1/8 twist bbl, for long ranch woodchuck hunting.
Since this will be a tight neck I will have to turn the necks, but will I also have to ream them, since I am necking the brass down? Is the process different if I use 284 Winchester brass? What is the difference between 6.5x284 Norm and 6.5x284 Winchester brass? I know I am asking many questions but I don't want to spend a lot of money on a custom rifle and not be happy with it. I can't use more than 100 grain bullets for calibers over 25, that is the reason for not building 6.5x284.
Thanks for the input.

as simple as running the 6.5-284 case thru the FL die. When you stick the mandrel into the case mouth, you establish the case ID; then just turn the case necks to match your chamber.

They are basically the same case. Going to 6mm is a simple neck down. You say you are going to turn the neck anyway.


As usual just my $.02

You MAY find that the base diameter of the LAPUA and Winchester brass is different. So if your chamber is going to have a tight butt it is a good idea to get some samples of the brass and measure them.
