    Do I really need this for reloading .223? I don't think I need the riser. Could I not just get some longer screws at the hardware store? This is of course, provided I can find a combination that works with the disks I already have. Even if I can't find that combination, could I not just run each case through the measure twice, as long as I verify the charge?

    You need the double disk risers to prevent binding, but you can make your own. As cheap as the DD kit is I would just buy it since you'll need the extra disks anyway. I wouldn't advise running the cartridge case through the measure twice, especially when using fast powders for reduced loads.

    Depends on the powder and what you'll accept. A single disk will load a charge of some powders that will work in .223, but there aren't many options, you'll have maybe the two largest choices on the disk. If you don't like what either throws you will need to double up.


    I think(don't mark it as gospel) I was getting about 20ish grains of 2230 on the second to largest and 23 something grains on the largest.
    20-21 grains is below the starting charge in any book for a 55 grain bullet, if I remember correctly.
    You can load double smaller charges, a triple would over fill so there isn't much chance of that.
    If you are loading for a bolt gun you won't mind, if you are loading for an AR it will be awfully slow going.

    With a double disk kit there are a lot of fine tuning options.

    I've also used the double disk on other loads to dial in the exact powder I wanted by using rather than one large disk two smaller disks. I've even take mine to a triple disk setup by simply having extra double disk spacers and buying longer screws at the local hardware store.

    yeah, you need the double disk kit for just about any powder you want to drop into .223. Most take 20-25gr of powder.

    I already have 3 disk kits so I got some springs to go over so longer bolts. I yet to use it but it looks good.

    Yes. Need to double stack in order to load rifle rounds.

    You won't need this for .223 but if you want more infinitely variable powder charge adjustments or larger powder charge drops, you can modify a micro-charge bar by filing the two slide points (see yellow arrows below) and use it double-stacked with the double-disk kit set up.

    I metered up to around 47 grains of I4895/H4895/Varget and 48 grains of RL15 and I didn't even max out the adjustments. :D

    Double Disk vs Double Stroke

    Yes, you can double stroke the auto-disk measure, but this is only practical if you are using the spring return, not the chain (using the chain requires a full stroke-see below).

    You have to remember (on turret or progressive presses) to short-stroke the press to avoid having the shell plate or turret advance.

    You have to remember to double stroke the press (if you don't, you will have a half charge) and remember NOT to triple stroke it.

    Because (with the double disk kit) you can mix different cavities, you can get a more varied selection of charge weights. Double stroking means you are using the same cavity twice which makes it less flexible in charge weight choices.

    All in all, double stroking is a poor substitute for a double disk kit. Less convenient, less safe and less flexible.

    But you can do it and get satisfactory results.
