Re: Need advice about 204 Ruger
Try seating the bullet out as far as you can, in order to get closer to the lands. Make sure you have at least .5 caliber deep in the case neck. Then shoot some groups, loading one at a time, and see if you accuracy improves. Could be a rough barrel and have little to do with excessive freebore. If the barrel is crap, then rechambering it would be even more of a waste of money. I always lean towards custom barrels as opposed to redoing factory ones, when accuracy is a concern.
I would also adjust the trigger as low as it will go as this helps tighten groups. Best of luck.
