Hey Ck~definitely my personal opinion, but I've had lots of rimfires come and go over the years too. So maybe a little experience too.

Bolt guns are more accurate, the triggers are almost always better (lighter always, less creep usually) and the action is solid. Semi 22s are blowback, so part of the energy from the shot going off cycles the action. That will always mean some accuracy is lost, no matter what semi you're talking about. However, among semis...some are better than others (I've had plenty) and I'm down to 2 of them~both Marlin 795s with tuned triggers. Still, they don't touch the accuracy of my bolt guns.
I've been a Savage centerfire fan for some time, and just bought my second new one a few weeks back~a Model 10 Predator in .243. I gave Savage rimfires several chances over the years, and have owned 2 heavy barrel HMRs, 2 x .22 rifles, and a model 93 heavy barrel in 22WMR. All that remains is the Savage Rascal my kids have basically outgrown...but still like to shoot...so it stays. QC was never great on these guns, and has only gotten worse in my experience. I've had guns with terribly rough machining, faulty mags, crooked scope bases, damaged crowns, and so on. With this deteriorating QC came increasing prices...so I simply had enough. Most were accurate, I'll give them that...but no more taking chances on mail-order rifles I can't inspect first. Not dismissing them forever, just no temptation to add another any time soon. The Ruger American, while I have no experience shooting them...appears to be a fine example of what a budget-rimfire can be, and while my own 10/22 experiences have been lack-luster (to put it mildly) the 10 round rotary mag that feeds it is superb. The Marlin XTs are around $75+$100 less than a Ruger American (depending on what you pick) and while they aren't quite as nice as the RAR's, they're likely every bit as accurate. Maybe even more, depending on who you ask.
Bottom line for me~hunting means being as accurate as you can be, so picking rifle that has a mediocre track record for accuracy (10/22) at the beginning seems counterintuitive.
Again, just my opinion. Everyone has 'em.
