Sorry, forgot the #1 is indeed a falling block and not a breakdown or "hinged" style single shot. Never owned one and been awhile since I've been around one. But as far as single shots go the falling block is the most accurate design. And just to clarify I think the #1's are fine rifles, but there's a reason most benchrest target rifles are a bolt action single.
