I got a 6.5CM rifle almost a year ago. I got a Daniel Defense and can’t tell you anything about the Howa.
However, I came here to say that I have been incredibly impressed with the accuracy with Hornady ELD-M 140gr ammo - I was making reliable hits out to 1400 yards. The ELD-X 143gr seems just as accurate, but I haven’t had a chance to fire those over anything more than 100 yards, yet.
