RCBS X-Dies: Do they eliminate trimming ?

I'm gearing up for bulk AR15 .223 shooting & reloading. Do the RCBS X-Dies work as claimed and eliminate case trimming or are they just another fad ?
If they work, would the small base X-Die be better for an AR15 ? So far I have had no problems using a standard FL sizing die.

I do not believe there is a claim by RCBS that the ‘X’ die eliminates case growth??? The instructions recommends trimming the case .020 thousandths before starting, if the ‘X’ die eliminated growth the case would remain .020 thousandths short.

I have not used an X die, but was reading the instructions the other day at a local reloading store with the shop owner. If I remember correctly, the instructins absolutely do claim that the X die eliminates case growth. You trim the first time to make sure they're in spec and after that the die does the rest. I cannot attest to the effectiveness however, although if it does work it's worth the money.

After you do the initial trimming and get the x-die set, the case will grow .002", then stop as long as you only use the x-die on that case. When you get cases that you haven't reloaded before, you have to size normally, then trim, then those are good for the x-die.

I am using the x-die for .223 and it works as claimed. I did break the decapping pin early on, so I would buy some spares when you buy the x-die. It takes the standard headed pins. I only broke the one though. I trimmed down to 1.73" so when they grew they ended up being 1.75".

Looks like you've started this topic on several message boards at the same time....cross posting isn't necessary and is poor etiquette.

Posting the same topic on different boards is not cross-posting.

Posting the same topic on several forums is a good way to pick more brains , I'd say !
