CZ and Ruger make compact bolt guns that shoot the 7.62 X 39. I'm thinking of purchasing one for my son for his first deer rifle. My thinking is that he could burn up cheep ammo practicing and then use some good stuff when in the deer stand. Today I asked the counter guy about the CZ he said. "You don't want to do that. 7.62 X 39mm is so inaccurate that your son won't be able to get affective practice?" So my question is. REALLY the boy is ten. Is that round so inaccurate that at 50 yards its going to be not worthy to shoot?
