I have a question about my new Ruger Hawkeye 300 winchester magnum. I bought this gun new about 6 months ago after selling my 7mm magnum. the first time out I was able to get about 3 inch groups at 100 yards from a bench rest. I waited about 2 minutes between shots and the shots seemed to be stringing vertically more than horizontally. I took it back to my shop and cleaned it thoroughly, re tightened all the screws and free floated the barrel. The next time out I was able to get just over 2 inch groups . Both time I was using cheap wal-mart ammo first Remington core locked, then winchester silvertips. My son-in-law bought me some Winchester supreme ammo for Christmas, but I have not been able to try it out yet. How much difference does quality ammo make? Have you heard any bad things about the new Ruger Hawkeyes in terms of accuracy? I do not expect a tack driver but I would sure like to get about a 1.5 inch group out of it. Any other suggestions?
