Leatherstocking –
The Ruger rifles in general are capable of outstanding accuracy and I have the targets to prove it. I would not worry about your test results but, rather, would be encouraged.
There are a couple things I do to my Ruger rifles. The first is I free float the barrel and reseal the channel. This takes about 20 minutes or less and requires a screwdriver, Magic Marker, a couple grades of sandpaper and some polyurethane. Remove the action and barrel, loop a half-sheet of sandpaper around the Magic Marker and start sanding. There will be a bump near the tip of the forearm which needs to be sanded out and you will need to remove a bit from the rest of the channel as well. Reassemble the rifle and try to slip a dollar bill between the barrel and the action. It should slide easily all the way down to the receiver. If it does not, more sanding is required. If it does, take a rag and dip it in the polyurethane, apply it to the freshly exposed wood, allow to dry, reassemble the rifle and do a final check. Done!
The second thing I do is polish up the trigger. Ruger triggers are very easy to work on and they can easily be polished up by following instructions readily available on the web. If you are not comfortable doing this, a gunsmith should do it for reasonable fee and replacement triggers are available. Actually, I free float the barrels and tune the triggers on all my rifles, so no big deal for me to do this to my Rugers.
With good handloads all of my Rugers will shoot under 1-1/4”, most significantly under (I have several that have shot groups under .5” when the wind was cooperating and a couple that have done half that) . I expect the rifle you are looking at will shoot quite well also.
