Well ask yourself whether the 'comp' guys have a focus on hunting accuracy, or bench precision.
For cold bore accuracy you want a barrel that is stable (stress free) given the wide range of ambient conditions that you have with hunting in the field. This is not the same as group shooting with a barrel brought up to hot with sighters.
A cut rifled barrel works well for both uses. They are also built well, having actual twist ordered, where many button rifled barrels are neither(you just get what you get).
Yeah there are button barrels that shoot well enough for both, top brands. But all cut barrels are top brands. There are no el cheapo cut rifled barrels.
I've used Wilson, Bartlein, Krieger, Border, Schneider, Pacnor, and would never recommend the last two(both button), for hunting. They were good only for grouping.
