I picked up a very lightly used CZ 455 in a trade a couple of years ago. I finally took it to the range earlier this week along with a Savage MK II to see how it shoots. I tried 12 different types of ammo including CCI mini mag target, mini mag varmit, stinger varmit, velocitor small game, standard target, SK standard plus, rifle match, high velocity match, Eley target, Aguila target compition, incepter, and some Winchester silver tips. I shot five 5-shot groups at 50 yeards of each of these with the CZ and 2 or 3 of each with the Mk II for comparison.
Most of the CZ groups were running about 2 inches with a couple getting down to inch and half and some up to 3. Most of MK II groups were sub 1" with a few below a half inch. The CZ was clean when I started. The MK II had several hundred rounds from the a couple of weeks earlier and hadn't been cleaned yet. My $189 10/22 with tech sights shoots most ammo better than the CZ. Highly disappointing. Do I need to be looking to get rid of this thing, or any suggestions on getting it to shoot better short of pillar bedding or putting a Lijia barrel on it? Either of witch would probably cost more than I have in the gun.
