This will eliminate most of the anvil as well. Open up Flash hole with 1/16th" drill, to clear a normal large Boxer decapping Pin.
It may be necessary to "Clean up" the pocket with a Primer Pocket reamer.

Anneal these cases...they are "OLD"...and you can then reload them several times.

I have done several 100s of these shells, first reloading with RWS#5005 (.199") Berdan primers, then as these have been getting scarce (Down-under) I have turned to "converting " to Boxer. For this work it is essential to have a mini-Lathe.

Thanks for all of this information. Unfortunately, I don't have a mini lathe and really can't justify one just for this project; at least not yet....

I've read a post or two about reforming .303 Britishicon brass for this caliber which looks like something I could handle. Also, I received 20 rounds made from reformed/reloaded 30-40 Kragicon brass with the rifle. Which would be the best to work with the .303 or 30-40 if I definitely decide to reload for this caliber??
