The only rifle I have that is close to a target rifle is a Kimber HS. That rifle along with a KDF K22, a Mauser 201, a custom Rem. 581/541, a Sako Quad, and a Kimber Classic, all love RWS subsonic. SK Standard, RWS R50, Wolf Target Match, and PMC Moderators. Since most of my rimfire rifles are catered towards hunting, I lean real heavily towards the RWS Subsonic since they are hollow points.
And like many here I have many different types of 22lr. ammo, finding it fun to see how each rifle shoots them.
