The present invention relates to a method and an arrangement in order to make possible, inshell-firing weapons with rifled barrels (1) made of steel, inductive transmission of programming data from a programming device (11) connected to the weapon to a programmable time fuse (21) arranged in the respective shell (12) while the shell (12) is situated in the cartridge chamber of the weapon. According to the invention, the steel barrel has been provided with an insert (4) made of non-magnetic material which surrounds the cartridge chamber of the weapon and which moreover cannot form a closed electrically conductive circuit around the shell and which therefore will not disrupt transmission. The electric transmitting coil (8) necessary for the inductive transmission is then arranged in a groove (7) around this insert while the shell in turn has its own internal receiving coil (18).
