I have a CZ 550 American in 6.5x55, a CZ 512 .22WMR, a CZ 75 SP-01 Tactical, a CZ 82 and a CZ 83. The thing I like most about CZ is the accuracy that I have experienced with them. My 550 American is very heavy which is good for me b/c I have a bad shoulder.
I used to own a CZ 720 shotgun for my daughter but sold it. I own four Winchester SX3 shotguns. I prefer CZ for rifles and Winchester for shotguns. This is just what I read, but I have read it a lot, CZ rifles tend to more accurate than Winchester rifles. I would like to stress that is what I have read, I cannot speak from personal experience since I have never owned a Winchester bolt action.
I comprehend how a projectile can, “lose velocity", but don't understand how a projectile can, "loose velocity".
