.303, unprimed brass

[ActionYobbo]

Talking of .303 brass........ I remember seeing a HUGE pile of maybe 60,000 cases from Vickers guns of fired .303". I wonder if anyone could invent a simple two stage gadget that would
a) de-prime and mill out the anvil, then
b) a second stage to perhaps drill a third fire hole that would bring the total surface area of the (now....) THREE fire holes up to the total surface area of the larger single boxer primer fire hole and
c) If necessary, bore/ream out the existing primer pocket to accept a currently available primer.

Has anyone thought of this? Not being an ammo man and never had to reload or ever had to buy a round of ammo in his life - so far - it just seems like a simple idea

its fairly simple. I have been converting berdan 303 to boxer to feed the hungry BREN. the WW2 brit cases last longer than modern commercial cases
