What have you killed with the 8x57?

Another 8x57 added to the fold. The recent CZ 600. 20 inch barrel doing 2530 fps with the Norma 196gr load. Ready for use in the field.

The rear is the set trigger - lightens up the pull on the main (front) trigger.
That’s the double set trigger setup.
You are correct that some rifles have a single set trigger where the trigger is pushed forward to set and then used as normal.

Exactly. I have two rifles with set triggers; one is a double-set and the other (a drilling) is a singe-set. The usual trigger pull is quite heavy (something on the order of 10 lbs.) but once you set the trigger, it's a "hair trigger" that only requires ounces.

As far as can be seen in the photo, they could be 8x57IR cartridges, normally loaded with 318 caliber bullets. Therefore you could use them in a rifle caliber 8x57IR, but you have to decide for yourself about the condition of this old ammunition and whether it is still usable.
