    I finally sorted all my 223 brass today. I have right at 4000 pieces. So I am guessing the WFT or some similar hand trimmer is out of the question.

    By looking at Dillon's site i would need

    • a rapid trim
    • a separate carbide blade
    • its own toolhead
    • sizing die
    • universal depriming pin
    How long does one blade last?
    I am assuming 900 + rounds an hour are possible.

    Toolhead, Rapid trim sizing/trim die in .223, the RT1200B motor (comes with the blade).
    The blade has 3 cutting edges and is rated for up to 10,000 cuts a side.

    You don't need a universal decapper die, just use a standard FL sizing die with decap pin at station one (I use my Dillon which are SB), at station four set your size/trim die to match or just short not to bump the shoulder any further, then set your trim length by setting the motor height.

    My RT arrived just before I left on my trip to TX & CO. I'm going to set it up on a 550b tool head like Boxer stated, but in station 3 with a Lee FL die in station 1.

    Fun, fun, fun...

    I just use a Lee sizing die in station 1 and the dillon .223/.308 with RT in station 2. Buy it, it's worth it's weight in gold.

    Yeah, IMO any FL sizing die at station 1 is better than a universal. It will iron out the neck with the carbide ball and set you neck tension. Then the sizer/trimmer as I said before just mimics the initial sizing without setting the shoulder back any further. Just set the trim length.
    There have been guys that use a universal to decap, them size/trim with the RT1200, followed by collet/bushing neck sizing to set the neck tension with more consistency. I personally have never seen the need to add the extra step.
    I believe using my method... you are already sized so when you run it through the trimmer there is no stress on the brass as you are trimming, so the trim lengths are more consistent.
  7. I wish boxer would stop posting videos of that thing. I am trying to convince myself I don't want or need that thing!
  8. WFT is a great product. Very accurate and easy to use. Each one can be used for a range of calibers that are close in size. I don't see how you could go wrong. The accuracy and speed cannot be matched for the money.

  9. Oh, but you do!!! Since I bit the bullet and got one, I can't stop kicking myself for being such a cheap SOB and not doing it sooner.
  10. Keep in mind it can get pretty hot. Let it rest if it gets really hot. I saw a guy wrap it in copper tubing and pump water through it.to keep it cool.

    that seems a little extreme. It can't be good for the life of the motor or blades.
  12. Yeah. I would just do medium sized batches.

    I ran it for 300 .223 cases and then took inferred temperature, 120 degrees F. Do any of you diode domes know how hot is to hot for a motor like the dillon?

    The whole it get hot thing is way, way over rated... yes it gets hot, any motor does. I have done 800 case batches with very little, if any detectable difference in case length from start to finish.
  15. Remember its a electrical part. No lifetime warranty. I don't consider 400 a big run. 1200 is a bigger run.
