Not owned a CZ, though respect them. The T3 no doubt has a slick action, crisp light trigger and a Sako bbl....and they SHOOT by all reports - esp. in 6.5x55, though heard good reports on the CZ as well.
T3s have a 1 in 8 twist, preferred for the longest of bullets. The CZ may have an 8.7" twist IIRC or close to that - not sure how they spin 160s. They may do fine, but don't know. The Ruger as the T3 also sports an 8 twist, and owners most often report sub moa.
If you wanted to treat yourself look at the Sako 85 Finnlight, and of course there is always a Steyr, Blaser, and others, but that gets to putting a hurt on your wallet all the more.
I can say if I had to live with ONE rifle, and planned to roll my own, I'd look really hard at that Finnlight, drop it into a McMillan
Edge, and a good scope. Would do ALOT of things very well for my shooting and hunting.
