Anyone have any experience in reloading 223 for an AR?
I've been told it takes special or different dies, but I haven't found anything in the limited manuals I have. I also do not completely trust those telling me this. I asked at a big box store I was at today, and of course all I need is the most expensive competition die set.
The conventional wisdom is you need small base dies to get reloads to work in a semi-auto rifle. I don't find that necessary for my AR. Most will tell you that you need to full length resize your cases. What I usually recommend is to try full length resizing and if you have a problem with feeding then go to a small base sizing die. If no feeding problems, stay with that. Manufacturer doesn't seem to mean a lot but I do prefer Hornady, RCBS, Lyman, or Redding in no particular order.
Personally I neck size for my AR and have no feed or extraction problems but I keep the cases segregated and don't use them in any but my gun.
In conclusion go with what you got. If you still need to get dies go with a good set it's worth it.
Pecos, who hopes this helped.
