    Has anyone had experience with these dies?
    RCBS catalog says "Trim the case once-Never trim again!"

    That just sounds amazing when you're thinking about reloading large quantities.

    Thanks in advance guys.

    I'm using the .223 one.

    It has worked as advertised for me. I've had 5 reloads out of the same brass, no trimming yet.

    If you get one, follow the instructions. I'd talked to RCBS about it when I first got it, and they said the biggest problem was people not reading the instructions.

    BTW, the coolest thing about this is that you can potentially reload .223 on a progressive using the RCBS lube die and the X-die.

    Like so:

    I have used the .223 X-die and they're correct. You just need to trim the case once. The die is designed to keep the case from stretching beyond its spec length (1.760") when you resize. Mine seemed to work fine but I have a couple of thousand .223 cases and the thought of trimmining every one of those suckers back to 1.740" was just a little overwhelming so I set the die aside and went back to trimming when necessary.

    The best thing since sliced bread. Just ordered another set for my .308 from Midway (on sale for $47); still need to replace my 22-250 and 30-06 dies with X-Dies. I use the Possum Hollow Kwick Trimmer chucked in my Drill press for the initial trimming then followed up with my deburring tool; bought the drill attachment from Sinclair. I can trim about a thousand in just over an hour.

    "RCBS catalog says "Trim the case once-Never trim again!"

    Understand that means not having to trim again for the "normal life of a case", and that really isn't very long. Meaning, the X die has no helpful effect on eventual body or neck splits.

    ranger335v,

    Since I started using the X-Die on my .223 brass I haven't had one single neck split in over 10-15 recycles of the brass in the past five years. The only brass I have had to toss has been those where the primer pocket eventually becomes too loose to hold the primer tightly. The reason I'm buying the X-Dies for my new .308 is because of the success I have had the .223. Soon as I can afford them I plan to replace my existing 22-250 and 30-06 dies too.

    Have you seen any thickening of the necks using the X-Die?

    I was told, when I called, that they had been able to exceed 15 reloads w/ .223 brass and the X-Die.

    You're right, someday the case will wear out. I'm keeping track of a certain group of such cases, see what I can get out of them. Weather is warming up here, might even get out this weekend to expend them again. :)

    If we limit discussion to only new topics that have never been discussed, there is not really much point in a forum is there.

    +1 to that!

    Can anyone here explain how they work (mechanically that is)

    No, but I haven't specifically looked, either.

    When I shoot my current batch, I'll check and see.

    Got out to shoot my "batch" of X-die-processed .223 brass today. I have about, oh, 50 or so I've processed w/ the X-die and reloaded five times.

    Walkalong asked about thickening of the neck; I checked tonite and there's none. They measure the same as other brass which hasn't been "X-die" treated.

    I also was able to shoot a few good groups with this brass, i.e., about 1.25" for three. I'm still learning how to do that, but I was happy w/ them.

    Interestingly, the rounds w/ the X-die brass had a 26.5-grain load of 748. I also shot some other rounds w/ H322 (can't recall the load, about 24.2 IIRC). The rounds w/ the H322 were significantly worse in terms of accuracy.

    So, the X-die experiment continues. This will be the sixth reload I've done with them.

    I checked after the last time out last weekend--no difference between the neck thickness between the 7-time-sized .223 cases, and once-fired cases.
