Heck, I have a Savage 25-06 factory sporter that I have put as many as 25 shots at 100 yards inside a group you can cover with a quarter. That may not be .5MOA, but it's dang good, and not all that difficult.
A thin barrel is going to vibrate faster than a thick barrel. This means the SWITCH in barrel direction will be more transient and harder to nail exactly resulting in a harder to tune barrel. Just physics really.
