I am just going to throw out my first batch Ive been messing around with because it is all mixed matched at this point. Its all loaded at the moment so Ill toss it after firing or just put it away for just in case. I didnt know any better at the time. My new brass arrived today. Another question to add to the thread. How would you prep your new brass? I am going to run it all through my sizing die. But will I see decrease in accuracy until after the first firing? Its like working everything back up for the first time right?
JTB:
If the new brass is Lapua, run it through a Full Length Sizer and champher the neck. Load and shoot. After shooting them five or ten times, measure a few to see if you need to trim them. If you trim them you will have to champher again.
If Hornady or other brass, run them through a Full Length Sizer and measure a few to see if they are the same size. If so, champher and shoot. After five or so shots, measure length again and see if you need to trim.
Trim to minimum length if you trim.
Spend money on components and not annealing gear.
Getting a decent Forster or other collet type of sizing die will mean you won't overwork the necks and will never need to anneal.
If you think the accuracy will suffer from a first firing of new brass, you need to focus your money on components and practice more than annealing gear.
