Have owned several, and used one extensively for several years in Germany. It, the ones in between, and two I currently own (an 8x57R and 9.3x74R) were all extremely accurate (MOA -1 1/4") through about three shots. As noted, the thin rifle barrel will heat quickly, and I suspect, begin to flex against the shotgun barrels. That said, who is likely to be able to use more than three aimed shots at a game animal from what is essentially a single shot? I use mine often chasing grouse after a morning on a deer stand. Great guns, and a wonderful solution to a general bag environment.
