We tried that bullet profile and the longest I reliably could load in a CZ S2 stock barrel was 1.10.
I think what people are telling you is actually shooting them doesn’t matter. What matters is to have a reliable OAL which runs in your gun. This means do some tests by starting long with the correct crimp (empty cartridge with no primer) and keep shorting it till it always plunks and fits & feeds in magazine. When I find that OAL I personally make 10 dummy rounds to verify they cycle as I rack the slide.
I personally start at 1.15 and work my way shorter, which will almost be guaranteed not to function/plunk in you CZ.
Next step shoot them.
Since you can’t test them in live fire don’t make a huge amount until they are Chrono’d and verified as working the way you want them to.
Hope this helps.
oh one thing more, blues are good (I like them in 40 180 gr and 45 230) but there are better, longer OAL, profiles for 147 In 9mm.
