Which stock does it have? I've got an older Howa 1500, with the short 20" Bull barrel in .308 Win. Unfortunately it's got the "Pillar Bedded" Hogue, which flexes too much. I plan on getting a Bell and Carlson with the bedding block, but it's a low priority, as I also plan on getting a decent magazine feeding conversion, using AICS magazines.
Years ago, when I bought my Winchester 70 XTR .30-06, it had the "Tupperware" stock, and my "patterns" looked like that. I ended up getting an H-S Precision sporter stock with a bedding block, and it ceased patterning, and started grouping my shots.
Not saying that is your problem, but if it's not the optics, the bedding would be my next visit.
