Any ID Help With These Two?

[jonnyc]

#1 - 6.5mm Swedish ball round, RN CNCS bullet, brass case and primer. Anyone know who made it, and when?

#2 - What I will call for now a "5.7x20 Mini-P90". Pointed GMCS bullet, brass case, nk primer, purple case mouth and primer seals. The headstamp is 5.7 x 28 FNB 91. It doesn't look like a complete fake, but I do have my doubts. I was told by another collector, who has no stake in the outcome, that it was a legit experimental and had been in a previous Buttweiler auction. Any thoughts or history on this one?

No info on the 6.5mm "Prima Import"?

Can't help with the 6.5mm, but the FN could be genuine. There was an article on the development of P90 ammo in the October 2013 ECRA Bulletin by someone who used to work at FN, and a wide range of case shapes and bullet types were reportedly tried.
