Is it a needed step in brass preparation or just a waste of time. What are the benefits of it? Will it help in a more uniform speed if you are shooting over a chronograph. Comments and opinion needed thank you.
Precision target shooters usually debur the flash hole. This helps with uniform ignition of the powder column. The holes are punched and as a result there is a bur around the inside of the hole. I haven't done a test to see what difference it makes. There is a tool made for this procedure so evidently someone thinks it helps.
