    Hi Wingman, an option would be to get and re do the project with a 204 CZ , as the magazine is longer I believe and you could seat your projectiles just a bit further.

    Nah the .204 CZ 527 mag is the same as the .223 mag, the both will hold a max length of 2.350".
    Actually both the .223rem and .204 Rug have a Saami std COAL of 2.260". The .204 cartridge was designed that way to be able to run in the current .223 platforms.
    The 204 brass is a tad longer than the .223rem but it has a shorter bullet and throat.

    If I cant get anything to shoot well with the big jump to lands Ill probably redo the chamber with a .223rem or .223AI reamer (with a 6mm pilot) and then just use a separate 6mm neck reamer followed by a 6mm throater cutting little to no free bore.

    It was a mistake on my behalf not to check my reamers free bore against my mag limitation to begin with.. live and learn
    The other Zastava mini mauser project I have with the internal mag should lend itself better to the heavier projectiles with the 1-10" twist and std 6x45 reamer.
