This all depends what i am doing. When I'm plinking with anything but a semi, i will use what ever is cheap, on the shelf, and not called "Russian Junior". So at this point i am using Wildcat: It goes bang! When the semi comes out, i use Mini-Mag: Cycles well, goes bang! When i use pistols, i like Stingers: It cycles every time, reports very well, it goes BANG!!! When i take the Anschutz out, i like the 22 Quiet to play, and Eley to show off. Both shoot very tight groups, both go bang! That being said, i suppose it all depends what type of shooting i am doing. All in all, my favorite type of ammo is the type that goes "bang"
