Trying to remove/unsrew a barrel from a Ruger 77/22 Hornet. Is there a special action wrench that fits into the reciver and If so, were could I get one. Brownell dosn't have anything for the Ruger's. If I had access to mill and lath I could make one. (Made one years ago for Remington's XP100/600/660/700/Model-7/40X.) I have an aluminum barrel block that will fit multiple barrel diameters.
