I have one in .243 and it shoots about 1 1/4" at 100 yards, though it's prone to vertical stringing when the front end is rested in different locations. It's more consistent when the front rest is close to, or under the receiver.
Sighting-in these guns seems to work best with the left hand between the forend and front bag to simulate field shooting positions. After sighting in that way, I killed a yearling coyote offhand at 140 yards with it.
The weakness in the design is in the ejector system. I'd prefer an extractor-only design that worked on a cam instead of a spring-actuated ejector. A few empties have remained stuck in the chamber. It's a pain when it happens in the field because the best way to clear one is to run a rod down the bore.
