Doesn't really exist anymore
In Canada!
In the USA it is available but just not here.
Down south you can even buy new manufacture Russian Wolf brand .303 British FMJ ammo in bulk at reasonable prices besides still available surplus .303 ammo.
Up until very recently (at least 2015 when I was last down there) you could buy this at a number of dealers in the USA -
Greek Surplus .303 British Full Metal Jacket, 174 Grain MK7Z Spitzer, 2440 FPS, 480 Round Bulk Case, Grade A
Original .303 British ammunition stored for many years in a military bunker in Greece. This is real military ammunition, not commercial loads, it is so accurate and loaded to Military specifications. Exact tolerances are required and that is exactly what this .303 British ammunition delivers.
Founded in 1874, Pyrkal, known as "Greek Powder and Cartridge Company", is one of the oldest Defense Industries in Greece. As the main producer of ammunition and explosives in the country, they have been a crucial supplier during all the military conflicts, and historically a well established exporter to five continents.
This is true Military Spec MK7Z Spitzer .303 British! This ammo has a 174 grain Full Metal Jacket bullet, brass cased, boxer primed, non-corrosive, and is reloadable. The Greek HXP (HXP is the headstamp code for the Greek Powder and Cartridge Company of Athens) .303 British is one of the most sought after surplus ammunition still available. This is the ammo you need if you shoot a Lee-Enfield, Lee-Metford, or a Martini-Enfield rifle.
As with any surplus ammunition, each and every round should be carefully inspected before use and we recommend cleaning your weapon.
This super deal is very limited and when this ammunition is gone, there will be no more. Buy now and take advantage of this great deal on grade A ammunition.
