i sent you a PM about a CZ 550 heavy barrel varmint i have .... heres what i know about them, personally only fired about 50 rounds through mine...it is a cz550 grey laminate varmint gun, i mounted a bushnell 7-21x40 mildot on her, i too bought it for it's superior mauser k98 action, the gun shoots sub moa with prvi match 168 gr hp ammo... i also had a box of south african .308 surplus, brass boxer... it does about an inch to 1.5 inch group at 100 yrs with this ammo, i probably could have got tighter but just used it to get on paper and then went to the match ammo... once sight in at 100, i skipped all the bull and was shooting out to the 500 yard range, with the rest of the box, and maxing out the elevation on scope... it's 40 inch max scope for elevation... anyway 3 rd mildot down i could easily shoot rocks that ranged for 6-8 inches square that i had previously set up on the poles out at 500 yrs...yes they are accurate, people post 1/4 inch groups at 200 yrds often with these but you usually have to handload for that... great guns and CZ's are about the best value in my opinion when it comes to bolt guns... true k98 action with 3rd locking lug and all...also mag holds only 3 rounds not 4 like advertised..........
