[QUOTE="MagnumManiac, post: 2161157, member: 10755"] 1) Visual inspection for defective cases. 2) Weigh a sample of 10-20 random cases per batch (50 or 100 cases respectively) If ANY are more than 2gr different, I then weigh all AND measure case volume with isopropyl alcohol. 3) De-burr flash holes. 4) Pass all cases through a neck only die, whether a modified expander type or a bushing. 5) Fireform while doing seating depth tests and initial powder/primer combos. 6) Tumble cases, inspect, size and measure. Always measure AFTER sizing, trim if necessary, I let my cases grow while forming for tight chamber fitting, then when stable in chamber fit, I measure again, BUT I allow my cases to get within .005” of the end of the chamber and trim back .005” from there and keep them at that length. This is often .040” longer than the MAX CASE LENGTH. 7) Measure actual volume of EACH case, discard (set aside) any that are .2CC’s or more different. I will say that this is rarely more than 40 cases at a time for me. My hunting rifles get a little different prep, I don’t measure volume in every case, just a random sample size and don’t sweat it too much if they’re .1-.3CC’s different. I work up loads in fireformed brass, but actually hunt with new brass. I don’t get nasty surprises this way. 8) I don’t weigh my powder charges, at first I do, then I calculate the volume of the powder in CC’s and use my powder measure set to that CC amount. I never see a huge variation in velocity doing this, as when I was weighing powder, my Harrel gives .1gr accuracy with the method I use anyway. Nothing wrong with weighing powder, a Chargemaster is a good tool. 9) Do seating depth tests. To do this, take a middle load of a middle top 3 powder, seat bullets from touching (or .005”-.010” away from touching) go AWAY .010” at a time. If this doesn’t yield a good result, you can follow the Berger seating depth test. I use Redding and Forster Comp seaters for almost everything, as Forster don’t do any for a few of my cartridges. I also use a few standard RCBS and Redding seater dies as there are no comp seaters available for them. I also see many so called top shooters on YouTube that just pass the press handle down while seating with no thought in force. I do my seating slowly with even pressure. On some rounds I remove the case after half the bullet is seated and rotate the round 180 and fully seat. I see a difference on target doing this with my 7STW and 264WM. It also feels different when seating this way. However, I gave up measuring runout long ago, as I could not determine a difference in aggregate over 1 season of shooting at 600, so gave my measuring device away to someone that thought it was imperative to know such things. There[I] [/I]are also case dimension measuring tools, I like RCBS Precision Mics for measuring fired cases and shoulder bump. I also have the Stoney Point head space set and the Hornady bullet comparator set to measure base to ogive in bullets and case head to bullet ogive. I have 2 trimmers, a RCBS Trim Pro and a Redding mini lathe. I have the K&M and Sinclair neck turning tools. I don’t believe these are necessary for anything but precision rifles that use precision ammo. Cheers. [/QUOTE]
