lars_ger Posted May 22, 2023 Share Posted May 22, 2023 Hi all, I own a CZ TSO from 2018. It is my first pistol and my main use is Bullseye shooting (25m/~25yards) In the past I was able to shoot 8-9 but nowadays I have problems to even hit the 7. Since 2018 my shooting skills improved and with other guns I am more in the 9-10 range. I already tried different types of ammo, changed the barrel bushing and tried some different springs but no improvement. An of you had the same problems ?

yigal Posted May 22, 2023 Share Posted May 22, 2023 I bought new TSO in 2016 and it had a big backlash in the bushing. The best group I was able to make with it from 20 meters when the gun was in rest was 15 cm. I replaced the bushing and it immediately started shooting a 2 cm groups from 20 m. 10 rounds.

Probably by people without basic knowledge in this profession. sand bag is OK. Edited May 25, 2023 by yigal Link to comment Share on other sites More sharing options...

Sorry, but it's hard for me to explain, because English is not a language I can express myself well. The bushing in the picture has tight fit and should be installed by a pro.

zzt Posted May 26, 2023 Share Posted May 26, 2023 After one season of use my TS bushing wore badly. It was initially tight and shot good groups. At the end the season the difference between barrel OD and bushing ID was .007". I replaced it with a 10x bushing and accuracy was restored.

CZ custom hand fit ours CZ dealer ask from cz to sent new factory bushing (gun was still in the store.it takes few months to receive license ) that cost less than 3 eu. and they refused. good warranty service. i ordered from ipsc store perfect 50 eu bushing .(it's not cz factory part) Link to comment Share on other sites More sharing options...
asierra350 Posted May 27, 2023 Share Posted May 27, 2023 I went the expensive route and sent mine to cz custom for their accubushing, great results Link to comment Share on other sites More sharing options...

I estimate that my CZ has around 7,5-10k. Although I already replaced it, maybe it is worth to try the 10x. Link to comment Share on other sites More sharing options...
