[QUOTE="MattK, post: 1830794, member: 94150"] For consistency, I: (a) clean my cases in a vibrating corn media with a little metal polish for about 1 hour (b) remove my primers with a decapping die (c) anneal (after every firing!) (d) size with a clean FL bushing die (with the expander ball and decapping pin removed, bushing for about .002" neck tension) using Redding imperial sizing wax (which I wipe off after sizing with paper toweling) (e) clean my primer pockets with an RCBS primer pocket cleaner/electric drill (f) if necessary, trim to length and chamfer the mouth insider and out (g) clean my cases in a vibrating corn media with a little metal polish for about 0.5 hour And I: (h) turn my necks before first firing (i) use a 21st century hand priming tool so that the primers are seated to a consistent depth (j) dip my case necks into imperial dry neck lube (then wipe off lube to the outside of the neck) (k) dip the lower portion on each projectile into imperial dry neck lube (l) seat the bullet with a Forster micrometer seating die, preferably one which has been reamed with my chamber reamer I use good quality brass (Lapua and Peterson) and projectiles (mainly Berger) and I don't weight sort. I recently checked 10 of my Peterson 300 Norma cases and these wasn't 1 grain weight difference between them. But if there were large weight differences in my brass and projectiles, then I probably sort them by weight. And I measure out my powder with an A&D FZ-300i scale (because it has internal calibration) with AutoTrickler V3. I think that's about it. [/QUOTE]
