Well, maybe I am a bit of an ammo snob, but I only buy jacketed .22 stuff. The Winchester 333 junk also didn't do well in my Ruger Mark III, Glenfield 60, or my buddy's Ruger 10/22. I just won't buy it anymore.... and the only non-jacketed .22 you'll ever see me buy again is Eley stuff, for obvious reasons.
I've had fantastic luck with Remington Golden Bullets in the bulk packs or 100 round packs. For cheap competition practice, the 100 round bricks of Golden Bullets are a very well kept secret! When the guns aren't in use, I keep them loaded with CCI Stingers. They have a good combo of weight/velocity coming out of my personal .22 firearms, and don't change the bullet trajectory. These are great for taking out pests but rather expensive and hard to find, so I don't use them unless I'm takin' care of business around the house with them.
Another good brand of jacketed bullets are the Federal American Eagle bullets in the little 50 round red boxes. They're typically about $3.50 a box but they function very well. The brass is always clean and bright, and they come in a tray so they aren't all dinged up like you find in some bulk packs.
The reason I only use jacketed stuff is that I don't enjoy cleaning out lead from my barrels, and the rifling stays clean much longer. My groupings start to open up after about 150-200 rounds of lead nose stuff, and with copper jacket it seems I'll get tired of shooting before the groups open up at all. I've gone through a whole brick of Golden Bullets in one day and my Ruger Mark III's groups stayed the same.
