I have seen a you tube account of a guy trying to group sub MOA (I think) with a Howa 6.5 grendel.
He struggled despite his selection of handloads. Then learned that Howa's require time being shot in (my phrase for adding some copper into the bore to smooth it out.) Apparently Howas shoot better after they have been used a while.
He was unable to ascertain the kind of round count that it would take to get one to shoot really well.
I'd post a link, but I suck at that, and have forgotten the guy's name.
When I got both my Howas, they didn't group well, but I assumed that it was just 'cause I sucked at serious marksmanship.
Now I'm starting to think maybe we have both been improving....
