For a plinker rifle I have a Ruger 77-22. Problem with it these days is finding ammo at a decent price if you shoot much. I have since switched to fun shooting my Ruger 77- 220 swift and the Ruger 77- 243.
I am not having any trouble finding any primers or powder, Bullets I have to order for the 243 but other wise I'm good to go.
