OK, took some photos of the (much ignored) project. some .303 cases that are almost done, a few are ready to go but most need one more firing with COW (cream of wheat).
Here's the best pic of fire-forming the 303 british shells although they do work out OK, the rims are very tight and some will not close in my gun. (Verona LX501 O/U)
.444 works out much better I think, all close in the gun and no fire forming needed. Magtech brass even better, more room.
cream of wheat! tastes good and works great for working those british cases. Black powder gives the best results, less need to get a good seal.
