Sco77w Posted January 15, 2022 Report Share Posted January 15, 2022 I have a CZ 455 Evolution with a 20” varmint barrel. I’m currently in the process of converting to to use for .22 PR and .22 ELR so I’d like to input the details into StrelokPro but I’m struggling to find the barrel twist rate. I’ve searched the internet and get answers varying from 1:9 to 1:12. I cant see it stamped on the barrel either. any idea where I can find this info?

Sco77w Posted January 16, 2022 Author Report Share Posted January 16, 2022 Cheers guys. I’ve seen the 457 bull barrels are 1:16. I’ll see how I go using that. Quote Link to comment Share on other sites More sharing options...
welshwarrior Posted January 19, 2022 Report Share Posted January 19, 2022 1:16 is the normal for .22lr. Quote Link to comment Share on other sites More sharing options...
