most likely bear creek will not cycle on SV yet - may be in a 100-300 rounds time it will, but today it was still too tight and had some issues sporadically not going full way into battery - either chamber needs more polishing, or ramp, or both, or just need more wear and tear all around.
i do not think there will be any significant improvement from moving to SV ammo, and, again, CZ drives aguila and mini mags, and SV all into same hole disregarding of what it is, and pretty much any decent .22lr rifle is supposed to do the same - not may be to the level of the CZ but at least do an MOA group, not a 3-4MOA.
group 3 of bear creek was almost decent - if we disregard 3 shots that went low, but as of CMMG - dunno, i am ready to write it off as a complete failure. i would not mind to swap the barrel if there was any proof seen that it actually can be better, but so far i fail to believe it can be better, based on what i see online about it. those who say it is accurate do not post any proof, and only those who like me get groups like this - post pictures.
and here is how bear creek grouped at 50yds. it will do.
