when I want target and match accuracy I go to higher dollar target and match ammo[federal gold medal target ammo] is what I go for but there is better [I'm cheap and it works for me]there is Eley,and RWS and if I start shooting matches I will try them .Wolf is also supposed to be good.
If I want playtime, can killing firepower, I go cheap,Thunderbolts,Golden bullets,Peters,or the federals in the red box .These are mostly good for head shots on Squirrels too.
anything bigger and I get premium hunting loads like Mini Mags,SGB's and thier like.I reload all my centerfires but with the selection of .22's out there I don't get into messing around with thier specs like that.
