I know we just had a 17 topic but I just got a new 17 and thought you might enjoy seeing it.
It was a 22 hornet till a friend of mine had a good smith cut the octagon barrel off at the fore end, bore it out and sleeve it with a 17 barrel. It looks like a factory half and half! Then he chambered it in 17 ackley hornet. I talked him out of it on thursday
