A friend has the CZ550 full stock in 7x57.
It is a handy hunting rifle but not accurate enough for bragging rights on targets. I have to think the skinny barrel and long stock have something to do with that.
I had the 550, mannlicker stock, in 30-06 and it was a dream to shoot and very accurate---kicked myself around the block a number of times for ever letting it go---a 550 in .308 with the full length stock is a real "keeper"---John
As stated earlier, mine was very accurate, the only drawback was that after a three shot string at the range, it required awhile to kool down, especially on a hot day---it would keep them touching at 50 and an inch or so at 100--that's good enough for me with an out of the box rifle and factory ammo---
