A bit more details on my process. I’m not a competitive shooter, but I shot quite a lot. I try to keep my reloading routines simple, and avoid steps that increase workload unless I find meaningful improvements in results.
I use almost exclusively range pick-ups, and gravitate towards cartridges where I can expect to find free brass (in Norway, that means .223 rem, 6,5x55, .308win, .30-06 and derivatives). Brass is sorted by head stamp, and FL resized for the first cycle. From then, I use the Lee collet die for all cartridges for which I have such a die available. Some brands tend to be long, and I trim for length. Other brands of brass (like Norma), I often skip the trimming process. No weight sorting, uniforming, neck turning, cleaning (unless absolutely necessary).
I use (mostly) the NOE expander plugs designed to fit the Lee universal flare die, after slightly lubing the inside case neck with a nylon brush, and imperial sizing wax. My general standard for all GC and PC bullets, is 0.002in neck tension, while lubed PB bullets seem to work better with 0.001in.
I mostly use large rifle primers (CCI or WLRP), but I should really try some LPP in the future.
For lube, I use a home-made concoction with rather a lot of ingredients. I discovered this lube as I mixed 3 home-made lubes together (for practical reasons, as they seemed equivalent) and experienced a sustained improvement in accuracy. If this is of interest, maybe I could drop a link to a detailed description I made on another forum?
For lubed .30-cal PB bullets in .308/.30-06 I use around 8,5 grs of pistol/shotgun powder (Universal, IMR PB, Vectan A0, Vectan Prima V, Vihta N32c, Vectan Ba9).
I seat the bullet using standard bullet seaters, and leave the flare (unless loading for a tubular magazine). I think of a concentric flare as an adjunct in centering the cartridge in the chamber (just a thought).
The PB, lubed bullet that has been most consistently accurate for me, is the NOE copy of the #315. In my Howa .308, my 5-shot groups at 100m are in the 18-40mm range, shot from prone with support on a bag. Most groups just above 1MOA. This is one of my most accurate loads, actually.
