i have a ruger all weather 77/22 in 22win mag. i am looking for a stock that would work on this like my mcmillan htg? also does anyone have a write up for the right way to bedd this rifle once i get a new stock. is there a picatiny rail that i can use on this? finally where can i buy the conversion so i can shoot 22lr and 22 mag in this action. then i have to only change the barrel right?
