@Beavis I've tried a few of the heavy bullet .223 factory loads and when you get up to 75-77 grain they're going pretty slow. Belmont ammo has never been loaded for maximum velocity so can't imagine it would be any different.
The seppo's love Mk 262 ammo which is 5.56 NATO 77 gr BTHP but I don't think we can get it here.
I would like to try this Hornady stuff from Reloaders and cheap enough too.
