Been going round and round trying to find the best ammo for this gun. I had to send it back to cz for some trigger and ramp work and they fixed that nicely. Anyway, I was trying to settle on the best round and tried many 165 gr with mixed results. Then I sent an email to the gunsmith at cz here in the USA and he said they use the S&B 180 grains for all their testing. So I got a box of S&B 180 grain and saw much better results. Where most of the 165 gr ammo was all over the place at 15 yrds the 180 grain would give me 8" groups at 15 yrds. Through further testing I have settled on the Remington Golden Sabre 180 gr. At 3 and 7 yrds the groups are like 2" to 3"'s and at 15 yrds the groups were around 6". This gun doesn't seem to like the 165gr stuff but very much prefers the 180gr stuff.
The only thing I can figure is the slower velocity of the 180gr. allows it to "grab" the rifleing better which gives it better spin and therefore yeild tighter groups.
