This is the prep I use for all my rifles and new brass..
Fireform using cornmeal and light pistol powder charge.. out of the box with no further prep until the first bang. This opens the typically undersized necks and "shocks" the case so full pressure firing will not strain the web area... extends case life and makes the first powder charge firing more productive.
Many brands of brass are sized to min.. min... min spec out of the box. Throw that into a "fat" chamber and fire under high pressure, may damage the web enough to render the case useless in a couple more pops.
now the case has a semblance of the chamber and I will begin the prep - check case runout. If wonky, get the rifle fixed. Deburr, size the neck, outside neck turn (even if to skim the neck to clean off the high spots - ensure proper clearance, not all chambers are big). If using bushings, you can now control the neck tension vs bushing size by making the neck thickness fit. now the case is ready for a powder charge and bullet.
Work up and see where things are happy happy. Body size, neck size, outside neck turn, trim if needed, deburr. The forster bushing/bump die will combine the first two sizing jobs. They can be set independently which is really a nice feature.
After 2 to 3 firings, anneal the necks PROPERLY. Body size, neck size, outside neck turn, trim as needed, deburr... repeat until you toss the cases. Brass flows with every firing. Some cartridge shapes, brass alloy and pressures will cause the brass to flow more then others. It will vary from case to case in your batch. outside neck turning to remove the high spots on every firing ensures neck tension is as consistent as you can control and you remove the excess brass that will form the dreaded donut.
Brass may have started out even but I bet with some shooting, that will change. If you have to trim, you have to turn. Where do you think the brass came from?
Buy bushings with the expectations to adjust neck tension per thou but the brass is allowed to flow into whatever the heck it wants to. Skip annealing and wonder why case necks split or seating pressures change.
K&M hand turners will be around $125 for the first cal... $16 more for each other pilot.. lee auto prime shell holder as needed.
If doing alot of cases, I have mechanised my Forster case trimmer to get this chore done fast and consistently. For the amount of brass I need to prep, no way I am going to do this hand.
ideally, with this type of set up, I will target 1 to 2 thou neck tension. Maintaining the neck thickness, ductility is critical to my success at distance.
It takes time, but like all the other steps in making the best ammo possible, it is the investment that pays off when your rifle drives bullets into itty bitty groups way the heck out there.
YMMV
