I have a CZ 550 Varmint Laminate 22 250.
I can't begin to tell you how well this gun performs. I looked at and shot 7 rifles before settling on this one. The set trigger is mind blowing. Detatch clip, added bonus. For and fit, for me it's like a glove.
Off the tripod, at 100 yrds my grandmother could do sub MOA
Off the tripod, at 200 yrds, relax, sub MOA is not difficult
Off the tripod, at 300 yrds. Have not shot targets but have shot rabbits without too much difficulty.
Off the Tripod at 400 yrds, the guns capability versus mine makes it's first appearance. Coyotes, not a hitch.
I have a bunch of old fire alarms from houses I have replaced them in when I moved in. At 400 yrds I can dial in with my scope and hit 4 out of 5.
Without dialing in and using hold over with mildots I'll hit 3 out of 5 or better.
at 500 yrds, I can hit a big tide box, somewhere in the middle, but that's as much as I have explored at that range with this gun.
If you can get a CZ 550 Varmint Laminate, I would go for it.
There aren't tons of them out there from what i have seen. In fact, I only know of two other people who have them, and only one of those is 22 250. I met a few people on different forums in the States who have them, and their advice and oppinions and range reports are what solidified my choice.
Not sure where are you from, but if you'd like to try mine and are within distance, drop me a PM and you can try her out for a day.
Good Luck
