Deane,
Disfunctional does even began to explain it mate. One thing I will say is that its a sport that can show you every emotion from elation to frustration all in one day while your mates put shit on you regardless.
Now to the question at hand ...
1. I run all new cases through an FL die (expander removed) or shoulder bump die. This makes them all the same base to neck shoulder junction.
2. Trim all to same elength
3. Chamfer necks
4. Unifrorm primer pockets
5. Uniform and deburr flash holes
6. Expand necks with correct expander mandrel
7. Neck turn to required size. Dont turn with a hot neck turner it will change the cut.
8. Weight sort now all pruning is complete
9. Check concentricity
10. Neck size all cases
Once fired I check and trim to length again. Re- neck turn (do not re-set the turner from the initial run) as some brass movement is likely. Check concentricity again.
This is a quick answer and I have probably forgotten something but someone else will fill the hole.
As for learning use good dies ie Wilson, Redding, Forster.
Dont work on brass or reload in a hurry or when preoccuppied
Come down to the Bay anytime(as long as I am not working) and we can work on bench technique and wind reading.
