I have a Black Diamond 8x32 Fine-Plex on a .308 Savage that I have used for 1K F-Class. I found it to be a good clear scope, my only complaint was it doesn't have that much elevation adjustment, a 25 MOA EGW base fixed that.
I recently purchased another Black Diamond 6x24x50 Fine Plex, that has more windage and elevation adjustment, and is also fine for 1K shooting.
HTH,
