Our Omega has a very tight barrel. Even with a clean barrel, I really have to lean on it with the 300 gr XTP in a black crush rib. But, does that sucker shoot. Usually stays under 1" at 100 yds. Our Encore, on the other hand, has a much looser barrel. Crush ribs practically fall in. Even plain black Harvesters are pretty loose. Accuracy...well, on a good day, it will stay in 3".
