I have a little project in mind or returning a rook rifle from being a 410 to a proper rifle. Plenty have religned to 22 Hornet, and a few have been done to .222 or 223 and even 5.6x50r - albeit there are getting to more pressure than a rook rifle can withstand. 22 Hornet is the obvious and I will go with a 1 in 10 or 12” so as to be able to use non toxic for small game, and it also for vintage small bore target shooting. But the 17 Hornet has me intrigued. I know that the 17 HMR with non toxic shoots well and ideal for rabbits etc.
