The simple and correct answer here is "yes" (and why I'm primarily a bolt gun smith- only accurate rifles are interesting, right?).
Which is why (I'm guessing) they've now added a semi class to the Precision Rifle Series. Not that they were ever excluded- but even in a timed competition where speed is as critical as accuracy- I never saw any place in the top tiers.
We're not discussing whether a 4K semi can be more accurate than a $500 factory bolt gun.
Accuracy is all about consistency, perfect concentricity and perpendicularity of all the relative/relevant components from the bolt raceway to the throat.
The tight tolerances that can be achieved- and are
desired with a bolt gun- can't happen in an autoloader. It won't run... Bolts are routinely done two thou or less under the ID of a precision reamed bolt raceway (that's about 1/4 the thickness of a human hair clearance around it).
Now, the high-end custom semi's can get close- with precision machining of the components that push the envelope to maximize accuracy, while ensuring the rifle will go "bang" when the trigger is pulled. Reliability in competition is every bit as important as with a CCW (except your life isn't depending on it, natch).
Get any grit/sand or foreign matter in a semi where the tolerances are "too" tight- and it's goodnight. While "fun" to run, I have about zero interest in target shooting with an AK-47. Even the high-end ones, while more accurate than the military versions, are still inaccurate bcg slammin' Kalashnikovs. OTOH, I'd take that AK over a precision bolt gun for a "survival" gun in a heartbeat because I know I can bury it in a sandpit, pull it out, shake it off/beat the sand outta the bore and pull the trigger knowing it will do what is was designed to do...
But when it comes to pure accuracy (at any cost), the bolt gun wins
