Anyone know of a good website that would have reload data for the 7x57 round? I have a new (to me) CZ 550, dies, IMR 4350, a box of 140gr Sierra Game Kings and a box of Speer 145gr bullets. Or does anyone have a favorite load using these components?
The CZ will probably give good accuracy with all weights, but will perform best with the 140 an 145's due to its later design. The older Mauser style rifles were designed around the 170 to 175gr.
Hodgdon has 7x57 reload data online for IMR-4350 powder at:

Lots of good stuff on the Hodgdon site, thanks.
