POF mk7 to the same standards as British made?

[Fruler]

I have a bunch of POF mk7 1968 ammo and a few hundred rounds of royal laboratories 1939 mk7 ball... 303 British. I'm wondering if the bullet itself, of the POF ammo is constructed in the same manner as British made mk 7 ball? Such as a lead slug in the rear and a aluminum or wood pulp core to fill the tip... If not, how would the POF bullet be made? I assume if the PoF says mk7 on the box, it should be close to the British standard, right? Thanks. Glad to be here on this forum.
