Thread: .223 Ackley Improved

Don't worry about expensive dies in any Akley improved - just buy a set of standard Lee collet dies. They only do the neck which is the only bit you normally need to size anyway, and the improved case fits the standard dies.

Not true.. you will need the .223AI dies as the shoulder is 40 degree which needs a bump even with neck dies and the AI body is straight walled after its first firing, the .223 rem has a tapered case which would result in over resizing back to the under size .223 taper every time it is run through the dies. The brass wont last very long this way as you are essentially fireforming it every time.
