A number of folk have been helping me out with my 243 Ackley Improved, so I thought I would post a quick photo of the brass in its various stages.
There's also some info in the following link about the 243 Ackley Improved.
The photo shows how the brass evolves, on the left is a brand new 243 Win case, then next to it is a loaded 243 Win round, then after firing the case comes out of the chamber as an Ackley case shown in the third position. Finally the Ackley case can be reloaded as in position 4.
Thanks for all the help.
