Because of the thin chamber wall in the area of the threads, it bulged slightly and ruined my Douglas premium barrel. 220 Swift brass is larger in diameter at the base than 30-30 brass.
When I complained to Ackley he agreed the case was too big for the 310 Martini.
I have heard the 222 Remington worked out well and theres no reason the 223 wouldn't also. The breechblock face needs to be bushed and the firing pin reduced in diameter for rifle cartridges.
The Hornet, K-Hornet or Bee would be easier conversions because of the rim.
There is 222 rimmed brass in Australia.
