ok fellas i have a cz-455 american stainless in .22lr and bought a stainless 17hmr barrel to go with it. the 22lr barrel has proven to be accurate so i just switched to the 17hmr barrel to see if it proves to be accurate also. if it does my plan is to send both barrels off to be chopped and threaded. i was thinking 16.5" length for both barrels as the american profile barrel gets thicker closer to the action you get. would chopping to 16.5" get me enough shoulder on the barrel for my sparrow ss to butt up against?
thanks,
Big Ed
Really, that is a question for your gunsmith.
It should be fine though..
