They work and have worked. They have a cool nostalgic look IMHO. For the majority of hunting that is done at the ranges it's done at their really isn't a pinch of difference if you ask the animal hanging from the meat pole. Target shooting at extended ranges is another story which I don't really care to read. Been there done that I'm over it and could care less. Did I mention RN's are a lot cheaper when you find them versus their pretty colored, plastic, pointy nosed counter parts.

Keep your powder dry and stay frosty my friends.
