I feel your pain. I've tried 15-35 ip torque settings, shimmed the action V-block .04" to level the contact with the trigger housing. Close to 2K rounds of CCI SV, CCI SS Segmented, and SK Std+ and it's mediocre at best. Though I did hit a 10" steel round at 297 yds 8 times in a row shooting SV and 10"/6"/3" round swingers at 200 yds were boring. My gun definitely groups best with my Axion suppressor.
The ejection on my gun is very weak compared to my RAR Target in .17HMR, which has a nearly identical bolt, extractor, and ejector. I've heard Ruger has re-engineered the RPR chassis, though the rep I talked to would share specific info pertaining to the redesign. I'm going to request one and see if they'll ship me one.
Considering the average performance of the Ruger Precision centerfire rifles and was hoping it would at least shoot like a decent CZ.
