I found myself in possession of some .303 ammo. Was hoping to ID it with some help off here.

One box of the ammo is labelled ".303 MkVII" and the cartridge is stampped "DAC VII 1943". This box is obviously milsurp... corrosive primers? safe to fire off?


The other box is labelled "Mk7 ISAA" and the cartridge is stamped "RG 53 7" Milsurp? Corrosice primers? safe to fire?
 
The RG is for Radway Green Ammunition plant. 1953. The 7 is probably the mark number.

Sorry not much help otherwise
 
The DAC is Dominion Arsenal (Canadian) and, yes, Berdan (corrosive) primed. Safe to fire off? I think you'll find lots of 'nutz here who shoot it, and others who collect it.
 
The RG is Radway Green (British) Mark VII loaded in 1953 - this is Cordite loaded, corrosive ammunition (clean after shooting - as opposed to clean eventually after shooting). I have some in bandoliers that clearly state Mark VII Ball.
 
Yes, Radway Green 1953 Mark VII Codite AND Dominion Arsenals (Canada) 1943, also Cordite-loaded, also Mark VII Ball ammunition.

BOTH are loaded with Cordite (yea!) and with corrosive/mercuric primers (waaah!).

Both should be loaded with the 174-grain 3-piece composite bullet and develop a muzzle velocity very close to 2440 ft/sc. If it has been stored well, both could turn out to be good stuff.

A little trick when playing with ld ammo is to 'bump' the bullets just a tad: run them through your press with the seating die set to just push the bulets back into the neck of the case by a FEW thousandths of an inch. You will find that the stuff generally is more uniform after this has been done and should make better groups.

Hope this helps.
