Do we know if Ruger makes the barrel on that shooter or do they farm it out to sub ???
I remember a long time ago with the M77 first came out the Ruger made barrel was a crap shoot, pun intended, hopefully they have improved their QC on all barrels or farmed it out. I have since stayed away from Ruger centerfire rifles.
I have assembled about 5-7 10/22s for our family and refitted them with Elysium 10/22® bull barrels and Hogue overmolded stocks as well as some trigger work.
All of those, including the two in my safe, function with all brands of ammo and produce excellent results.
I believe that Elysium barrels are stated as match grade barrels and yet they seem to be able to handle the bulk ammos with their varying dimensions readily. If that Ruger barrel is a match grade chamber I would follow the advice given above on complete cleaning and tightening and then start with CCI stuff and advance through other brands. Should be good to go as far as functioning.
