[QUOTE="Petey308, post: 1641620, member: 106845"] I deprime with my Hornady LnL AP and case feeder using a universal decapping die. Then I wet tumble the brass clean. After they dry, they get annealed. After annealing, they’re ready to be resized. Which press I use for the remaining steps really just depends on how I feel or what I’m doing. Load development rounds get done on the single stage. If I’m loading up 100 rounds or more of a developed load, I’ll likely use the progressive with the case feeder, but sometimes I load on the single stage as well. I’ll put the Lee FL die without the expander ball into the first station, then the mandrel die in station two. My mandrels are made to produce .003” of bullet tension, which has proven to give me an excellent balance of speed and low SD/ES and doesn’t require any sort of crimp to prevent bullet setback from recoil, even in semi-auto rifles. After that, they all get trimmed, deburred, and chamfered. After that, they’re ready to be sorted. I sort cases by weight. I’ve ran a test to see if sorting by weight vs sorting by H2O capacity works better and the differences were minimal enough that I decided to just weigh them since it’s so much faster. Depending on what cartridge it is (size of the case), I sort them in batches with a plus or minus range of half of a grain to a full grain. Once sorted, I hand prime the cases. I prefer hand priming so I can feel every primer being seated and I know they’re consistent and not getting crushed by too much leverage from a press. I use Federal Gold Medal Match primers in all my loads too. Once primed, they’re ready to be charged. I use a GemPro 250 to weigh my charges. If I’m using my progressive press, I use a powder drop die with a funnel. My bullets get seated using either a Redding Competition micrometer seating die, or a Forster Ultra micrometer seating die. Both of those dies have proven to do extremely well. I verify my seating depth using a comparator and measuring my OAL from the base of the case to the ogive of the bullet. This method has produced extremely consistent and accurate ammo that I can count on. I only use temp stable extruded powders as well. I’ve experimented with uniforming primer pockets, deburring flash holes, etc as well. I still do it with some brass, but not all. I’ve done a lot of experimenting when it comes to reloading. It’s something I have a passion for. I also have a passion for ballistics, especially terminal ballistics. I’m always testing and researching bullets and how they perform on animals, especially at long range/low impact velocities. That’s a big reason I’m a member here. [/QUOTE]
