Experience Here:
Pretty much what Greydog says!
The ammo will also have to be
tuned correctly via reloading for that rifle and action. And some single shot actions/rifles do amazingly well with select (lots) factory ammo
these days.
Think harmonics and best fit ammo for a particular breech and action.
Expectations for the tune:
1 moa almost always possible.
.500 achievable, and consistent, depending on tune, action,
ammo selection/or reloading.
.300 and .200 will happen, but not consistently possible even from bench.
Single shots
will hunt, and you might occasionally win/place in a
match outdoors w/wind. Think
best of the best e.g.: action harmonics, shooter, wind-doping.
Just my 2 cents worth, and remember single shots are
always going to be slower under duress than a bolt action repeater when something can claw, bite, grind you to dust, or tear you apart,
!
