0,303" Drill round


Does anyone have any suggestions for the provenance of this 0,303" drill round?

The entire case and bullet are chrome plated. The bullet is non-magnetic. The primer pocket has no anvil or fireholes. The bullet appears to be soldered into the case as well as having three neck stabs. There is a suggestion that the flutes might have contained paint at some time.

The oddest part is that the base has been filed prior to it being plated and this has removed most of the markings save for the ‘VI’ seen in the picture. This is at 6 o’clock. If stared at long enough there is a suggestion of ‘R L’ at 12 o’clock.

In anticipation, Peter


I suspect that you have an early .303 Drill Mark VI, pre 1926 when the “D” was allocated to drill rounds and included in the headstamp. The R^L headstamp with the two dots at 4 and 8 o’clock is typical of these rounds.

The cartridge case would have originally been white metal and the bullet jacket CN, but in 1934 the Royal Navy decided to chrome plate all their stocks of D.VI and the mark was advanced to D.VI*. Usually the “*” was added to the headstamp but not always. Similarly, sometimes the bullet was chromed and sometimes not.

I am not sure that the casehead has been filed. It may simply have been a weak strike and a combination of hard use and cleaning before plating has left it very faint. Also, the red paint does not adhere well to chrome so easily wears off.




Thanks for that. Is it normal to have the bullet soldered into the case in addition to the stabs?



No, not for the D.VI,although earlier marks were soldered. Are you sure it is soldered and not an accumulationn of crud around the neck?
