New Manufacture No4 Barrels

[Beerhunter]

Do you mean a 174gr FMJ round for the .303 generally, or one with an aluminium core a la the issue military round?

He probably means174gn bullets with a flat base for starters.

There is a couple of guys in the UK who make them but they appear to hand-swage the jackets on and so they are FAR from Cheap.
