And by the way, guys, the sights were and are in YARDS, not METRES.
Nominal performance of the Mark VII Ball round was 2440 ft per sec, measured at 78 feet from the muzzle.
The Mark VIII (8) Ball round was specifically issued for the Vickers Heavy Machine Gun for long-range area fire application. SOME No. 4 Rifles were Proofed and accepted for Mark VIII ammunition, but by NO means all of them. Generally, Mark VIII ammunition should not be used in the No. 4 Rifle and it should NEVER be used for the Number 1 Rifle (SMLE), nor in any rifle preceding the SMLE.
Watch your ammunition carefully. There has been FN-made ammunition on the market in this country which was sold as Ball ammo. If you could read Flemish or French, it said on the boxes For Bren Machine Gun Only. Similarly, the South African ammunition currently being sold is loaded to Mark 8 standards; it should be used only in rifles displaying the Ring-8 stamp which was applied after Proofing with the heavier loads.
Also, know your ammunition before you start running loose rounds through your rifle. I was at a gun show a few years ago and got a hatful of very pretty Norma stuff for two bits a pop, nice-looking ammo with milled rims like a quarter. They were PROOF rounds! Be careful!
