I have 3 bricks of V315 Super Match pistol cartridges. I had an old friend that shot a little rimfire BR in the olden days and this is some of his old ammo that I have.
Anybody have any info on it?

Don't that exact Fiocci, but have used Fiocci ammo in my High Standard. SV match ammo, I think it is good stuff. Not as expensive as Eley or RWS.
