.22lr ammo prices can be in very wide range. There is bulk ammo that's on cheaper side and there is match ammo that can cost more than 5x. Semi autos may not like some ammo so one needs to test a few brands and varieties. Bolt guns are usually more forgiving but if accuracy and consistency is required then some testing of diff brands, varieties and lot numbers is in order.
I shoot only bolt rifle in that caliber and while CCI Std Velocity shoots well out of my gun, I like SK ammo better but it's more expensive; there is better ammo but it makes no diff or sense for my shooting.
Subsonic or standard velocity ammo normally shoots more accurately and consistently but if you need to go beyond 300 yards you may have to use high velocity ammo.
