Whats wrong with just under 1"? I looked at a 550 recently and that was a hunting rifle. I think that much to much is made of superduper accuracy and a good deal of it is easier to tell about than to do. Meaning a guy shoots a .5" group once so he talks about his .5" rifle. It would be pretty hard to buy an honest .5" rifle over the counter, even with the best reloads.
