Yeah this can go anywhere. I've seen spotter barrels shoot .5 MOA no problem, and I've seen M24 contour barrels shoot .1-.2" groups. All will shoot accurately if its a quality barrel with quality smithing, contours really start playing into effect on repeated rounds (as the barrel heats), you'll also run into a lot of opinions on fluting, some people argue it stiffens a barrel, while others say it does not, but keeps the same stiffness while reducing weight. Fluting can also warp the barrel if not done properly (usually its a good idea to have the barrel manufacturer do any fluting).
