I am pretty new to turning necks. Using a Sinclair turner on lapua 308 brass for LR FT/R. Last year I shot unturned un sorted brass and I doubt that my brass held back my skills. That being said I want to get my ammo better to give me my skills as much of a bolster as I can, so here is my situation:
I bought 1 box of lapua 308 win brass for my new FTR rifle. I neck turned it all to 0.0147 to give me a 90%+ clean up, meaning that no more than 10% of a case neck was left un cut.
I bought another box of lapua 308 win brass and am turning it all to 0.0147, but it is only cutting approximately 50-60% of the neck.
My questions is, is it better to have all necks cut to 0.0147, and have a little less consistency on any given case, or should I turn box 2 of brass a few ten thousandths thinner, and have one batch of brass slightly thinner than the other?
The way I see it, any clean up is an improvement over factory brass so cutting all necks to 0.0147 will not put me any worse than factory brass, and should be at least slightly better. Where as have two batches a few ten thousandths different in neck thickness may result is significantly different neck tension and could, therefore result in one batch having poorer accuracy than the other (or not).
I know the ideal is the cut all brass to the thin enough to get a 90%+ cleanup on all brass, but Id rather not do that since I have already developed a load with the necks turned to 0.0147. Any help is greatly appreciated as always.
