This is what I do and I have several rifles in multiple calibers that all shoot single digit SD and usually mid-teen ES or lower. All my rifles are 1/2 MOA or better and usually shoot 5 round groups in the high 0.3XX" center to center from a bipod and rear bag with me on the gun. Not a 30# bench rifle sliding in bags. This was intended to help a new reloader who is getting started to produce very good ammo with brass resized and tailored to their own chamber. Not the n'th degree of what is possible at a reloading bench.
What I am loading for is PRS matches where our typical engagements are on a 2 MOA target at various distances and props. I can guarantee you that these methods, with a little bit of load development, will yield accuracy superior to anything you buy in a box. Now if this is for bench-rest then perhaps more work at the loading bench will yield higher scores and tighter groups. However, for PRS style shooting using that added time dry-firing off barricades at 1 MOA targets will improve your scores more than neck turning or mandrel sizing an ID. I also stick to Lapua brass, where I can, so that certainly helps. For any type of field shooting, PRS style, Hunting, Plinking, Ect. Anything more than these methods are wasted effort IMO. Benchrest, maybe more work yields tighter groups but I don't play that game so I can't say.
In regards to Annealing. I am still not convinced annealing is required but I try to do it every other loading on a Giraud Annealer.
Again, leaving the expander ball just uniforms the ID of the neck to "round" but ruins the proper neck tensions set by the proper bushing because it opens up then neck slightly. It does nothing to the shoulder or the wall thickness of the brass.
