Most guarantees are for a 3 shot, or in a few cases, maybe a 5 shot group.
Lots of stuff will do the 3, so that's pretty meaningless, IMO.
I'll take them seriously if the say a 10 shot group & mean it & back it up..............so far no one does that I know of.
Ammo is huge & the shooter is not insignificant either.
A few barrel makers guarantee <MOA or user satisfaction ...........
