    New to reloading, what is the process? Do you deprime first and then tumble. I would imagine you deprime and resize and then tumble.

    Any pointers would be great

    You don't want to send your brass the through the resizing die when it it dirty. Dirt and grime can ruin your resizing die over time.

    I'm sure others will have methods that work just as good, but I deprime using a Lee universal depriming die and then tumble and then run the brass through the resizing die.

    Personally, tumble, deprime/resize.

    By tumbling first, you do not have to punch the medium out of the flash hole before loading, but if the case is real dirty, I usually tumble before putting them through the die. Either way is fine and just depends on what your preference is. If you tumble them after de-priming them, then the primer pockets usually are pretty clean for loading. I do both methods depending on the condition of the brass.

    Get the depriming die and do that first, then tumble, and resize. I tried the tumbling first, and little bits of corn cob will stick in the flash hole. Then when you try to deprime, the depriming pin will get blocked, or pushed to the side. I broke/bent a few depriming pins this way.

    Soon as I get back from the range/hunting, I hand deprime using one of these:
    DECAPPING TOOL
    Then I swipe the pockets with a pocket cleaning tool(like a blade screwdriver), and wipe case necks with a rag & CarbonKiller. Drop em in the vibratory cleaner.
    If you intend to keep carbon off your brass, it's easiest to do so as fast as possible.

    After of few hours of cleaning I dump into a sifter, and pull cases each while taping the caseheads with the handle of a small screwdriver to knock bits out of flasholes. Works just fine, and I set them in a loading block ready for sizing.

    After sizing, if I needed to lube cases(for shoulder bumping), I drop them back in the vibratory cleaning for an hour to remove the lube. Otherwise, they're ready for priming, charging & seating

    I do this exactly minus the second tumble. I'll wipe the lube off with an old t-shirt. Other than that, identical.

    Deprime first!! Its easy to bend deprime pins otherwise. After that do whatever you want.

    I tumble to clean and THEN kick the dead primers out and lube and resize. No sense running any gunk off those casings thru your resizing die to wear it out faster.

    First thing I do is clean the blow back off the brass with 0000 wool while the case is jigged in my power drill and a univeral shell holder. Then I decap with a universal decapper, then lube it and size it. NOW, that I have my brand new Thumbler/tumbler, I use those to clean and let me tell you it works AS ADVERTISED. Looks like brand new shiny brass inside and out.

    Then I trim, chamfer/debur and reprime and they are ready for the next load. I also just got in the mail 2 days ago my Sinclair/Wilson power adapter and a new cutter. Trimming cases has never been so easy/fast.

    I second this approach. I deprime all of my brass on a Single stage press with a Lee Universal Depriming Die before I tumble them. After tumbling I inspect all primer pockets for walnut and/or corn cob material.

    Just as an added note I do resize all my rifle brass on my single stage press before trimming on my Giraud Trimmer. I then reload on my two Dillon 650s presses (one setup in SP and one setup in LP).
