This question about light profiles and fluting came up during the group buy and Dan answered it directly. I found it and pasted his response in red below:
Is there any truth to this remark on the forum thread, “I think a lighter contour barrel is will be nearly as accurate as a bull barrel, but you will probably notice a POI shift after a 10 shot string.”?
Not with our barrels. Impact shift comes from stress remaining in the barrel coming out as the barrel warms. Our barrels are stress relieved in a vacuum furnace so this isn’t a problem.
