I think most guns with a guarantee will meet it, in some form or fashion.
Generally speaking accuracy does not come with hunting bullets out of the box so to speak.
It does NOT come from ball FMJ stuff.
It comes from match grade, meaning maybe to the point of brass prep, sorting, unified pockets, tested primers, tuned powder charges, proven seating depths and neck tensions. PLUS a TOP line shooter.
That said if the twist works, and it won't shoot federal gold medal match 69s, it may not shoot much of anything.
Beware if its 3 shot or 5 shot groups, distances guaranteed etc... although 3 shot groups, if repeatable, should be more than good enough for 90% of the folks out there.
RE weight... I have a ACCURATE 308 bolt rifle... its also veyr heavy... in there is a theme of sorts, light super accurate are not as common by far.
