First I took RIO,s advice and bought redding 3 die competition set. It included a body die, type s neck bushing die, and a competition seater die.
I experimented with a few different things and this is my final process that I ended up with and have finished 300 pieces so far.
First I take all the internal parts out of the bushing die, put a little imperial wax on the case and make 1 pass through the die.
The necks come out extremely long, so I cut them down on a chop saw and then chamfer the outside of the necks so they are smooth for the next step.
Second I run them through the body die and then do a final trim length.
The body die leaves the inside of the neck a perfect size that I dont have to use the expander and they are ready to neck turn.
I then turn the necks to the desired size.
Then I chamfer inside and outside of the neck, uniform the primer pocket and debur the flash hole.
I then anneal and my third and final step is to run them through the bushing die with the bushing and the expander ball installed in the neck die. Then load and shoot.
This is my first group shot with my new cooper with my newly formed brass.
It was a little intimidating at first but today I am going to make up another 500 pieces.
It looks like the process and the rifle show some great potential. I know it is only a 3 shot group but I didnt have much brass made up yet and didnt want to make much until I was sure what type of accuracy I was going to get.
I think it just might work.
