Last one for now.
%20700NE%2019%2091%201-1
Who is this one by K.A.?

Thanks in advance for the help, A mate has been given loads of these, all inert but not a clue what they all are, been trying to help him sort them out.

Thanks,
Mike.

The two “C”'s stand for full Cordite, Also seen is “L” “C” at 9 & 3 which means Light Cordite which was a Nitro for Black load.
The difference in the "C"s in merely time, the .450 is older manufacture.
The bullet looks Ok & copper tipped to improve expansion. Is the bullet magnetic?
No help on the KC 700

K.A. might be Kynoch Ammo or Kynamco, which is just a brand name, not a manufacturer as I understand it?

Copper point 235 gr.

Thank you all for the help, much appreciated.

Just the 700 to tie down if possible.

Thanks,
Mike.

Hi Pete,
Yes, it is magnetic.

Mike.

I don’t know who K.A. is, but the font shape, size, and spacing of the 19 9 and 700NE looks identical to the BREVEX 1993 700NE from France, so that might be a clue to the origin.

On the first one, “R - P” stands for Remington-Peters.
