Nice rifle Chief. Been a big CZ fan myself for a long time. I have a 453 with a set trigger, and a 457 which is my ARA 50 yard gun. Both are way more accurate than they have a right to be. They both do their best with Eley and SK match ammo. And it seems to me that my new to me 1933 Winchester 52 is partial to SK Standard and Wolf Match, both affordable, and shooting sub 1 inch at 100 yards.
A real sleeper is my Kimber .22 Hunter. It is a solid 1/3 inch rifle for five shots at 50 yards. Sporter weight barrel and stock. And its favorite ammo is a particular lot # of CCI Velocitors of all things. Down to my last brick. Any other lot # won't come close in accuracy.
Day in and day out, I have found CCI SV and Eley Contact to be very consistent ammo in a variety of rifles for not much $$. That expensive match ammo is not really needed unless you are shooting for absolute group size, and only if your rifle likes it.
