I recently acquired a new old stock cz527 17 hornet. It's an older serial number. Looks like from 2013. It's proving to not live up to the accuracy claims I read so much about with these rifles. I have tried factory 20gr Vmax loads that barely group under 1.5" at 100yrds. Load workup with AA2200 hasn't been much better with Hornady 20gr Vmax and 25gr HP. Groups are sporadic. Next I'll try AA1680. So maybe I need to bed the action? Is there maybe something with older rifles I'm not aware of?
Also not a rifle issue but 17cal issue. My Oehler 35 has failed to read a single shot fired through it with my 17hornet. I have colored the tips of the bullets with black marker and still nothing. Makes load workup a little different. Other rifles in 6mm and 7mm picked up just fine on the same days. What are some things you have done to Chrono 17 bullets?
