According to Stuart Otteson's book "The Bolt Action"

Remington 700: blocks the sear and raises it off the trigger

Sako L461, L579: blocks the trigger and sear

Ruger M77 Mk I (tang safety): blocks the trigger

According to Frank de Haas "Bolt Action Rifles"

Browning BBR and A-Bolt: blocks the trigger

Brno ZKK600 series: blocks the sear

Ruger M77 Mk II: blocks the trigger


Other rifles that have the safety on the bolt shroud:

Sako L46 and L57: blocks the firing pin

Brno 21H: blocks the firing pin (actually probably the cocking piece)

Brno ZG-47: blocks the firing pin



If you want to be REALLY nitpicky, most of the bolt actions that have the safety on the bolt shroud (e.g. Mauser, Springfield, Weatherby Mk V, Winchester 70) actually block the cocking piece rather than the firing pin, as does the Enfield 1917, but since it is unheard of for a cocking piece to break off from the firing pin it amounts to the same thing practically speaking. I believe the Brno ZG-47 safety directly blocks the firing pin and not the cocking piece.
