I own a CZ 550 American in 7x57mm. I bought it in 2000 to replace a Ruger Mark II in 7x57mm. I think CZ offers the best bang for the buck going in the firearms industry today. The wood-to-metal finish was good, the barrel was freefloated and the stock was very pretty under that goop CZ calls a finish. I took the original finish off and re-finished the stock using GB Lindspeed Oil. I then glassbedded the action area of the stock using Probed 2000. With my handloads I can get half inch groups at 100 yards using Hornady 162 Grain SST bullets, H414 powder, Federal primers and Remington cases. Overall, I am very impressed with the rifle and I especially like the single-set trigger feature. The trigger is also highly adjustable. I have it set to break clean at 3# and left the factory setting of 12 ounces on the set feature. I had a gunsmith polish the bolt handle to a bright nickel finish and then do a small herringbone pattern jewell on the bolt body and extractor. I topped the rifle with a Leupold scope and Talley Rings. My hunting is limited to stand hunting, so the rifle's weight (Nine pounds even with scope and fully loaded) doesn't bother me at all. The thing is pretty with its Turkish Walnut stock and deep blue metalwork set off by the polished bolt handle and jewelled bolt. All in all, it is perhaps the best rifle I have ever bought and that includes rifles from Ruger, Savage, Winchester, Remington and even one semi-custom Model 98 Mauser in .284 Winchester with a Herters French Walnut stock years and years ago. The attachment is my CZ 550 American in 7x57mm and the kind of groups I can shoot with it. Tom Purdom
