Hi, my CZ 457 MTR shoots 36 grain CPHP CCI very very well.I cant find ANY to buy, and one website said/infered they might discontinue these rounds , does this sound right ? What have you CZ shooters find that shoots excellent out of these rifles ? I am thinking I might have to start buying ELEY HOLLOW ammo to get same results.I also read that the CZ with match chambers wont shoot STINGERS, cant get them into chamber ?
