I got my first 6.5 Creedmoor a couple weeks ago. I really like it. ! So far it is seeming to be a half inch rifle. Mine is the Hawkeye with the 26" barrel. I wanted the VT model with the 28" barrel but my dealer couldn't find one. I actually get so excited to shoot it that its hard to calm down and shoot good. I really like it! Not too big, not too small not too fast or too slow. Just right. .
Not saying its better than the 260, 6.5x55 or 6.5x 47 . But I don't think its inferior either.
Mainly it's in a Ruger and so I like and trust it.
