I thought that's why the MOD ordered all that lovely HXP 303 ammo from the Greeks back in the early 80's for Cadet use? There was still enough of it to sell surplus after they decided to stop using the No.4's, so was that really the reason? The UK NRA got a lot of it. I've got one box left, its very hard to find now, although most of it ended up in the USA.
