I owned one of their heavy barreled 77s in 22-250 for prairie dogs.
With a leupold scope and a carefully crafted handload (just a smidge taken off the powder charge, perhaps delivering 3500 FPS) I once placed a bullet through the spout of a soda can and out the bottom at 200 yards. Granted, from a solidly built bench on concrete, utilizing a Harris bi-pod at a gun club.
The action and trigger were box stock.
I had the same rifle in .243 Win. While not as precise, I could hit quarters at that distance. I consistantly shot groups which never touched into a perfect cloverleaf, but were darn close.
If need arises, I'd buy that same model again.
