.22's are "funny" beasts.
Lots of .22's in my family (dad, brothers, sons). Some like Thunderbolts, some like Winchester Wildcats, some like Federal, some like Rem. Golden Bullets, etc., etc., etc.
Just gotta buy different brands/types of bullets and try them.
But, it's a good thing if you have more than one good brand/bullet type you can be sure works well. These days you never know when the type you buy all the time suddenly dries up.
