Blasers shoot about 1" @ 50M for 10 shots out of my factory 10/22 barell, and also shoot decent groups from another 2 of my rimfires. I still haven't tried them in the new Kid heavy barrel I just put on that 10/22. I don't like the bare lead bullets either, but it's just a personal thing, since I haven't had any leading problems with them. Minimags shoot just as well in the same guns, and they have lubed bullets, so I prefer them.
Stingers are the best performing bullets in my Winchester M-77, but functioning-wise only. They are one of the most, if not the most, inaccurate load in 5 out 6 rimfires I own. I haven't tried them in the last one, but I wouldn't be surprised if they sucked in that one, too!
The Stinger's forte is terminal performance on varmints, so I've used them for hunting in the past. However, they're so inaccurate for me that it's not worth it using them for that anymore. Specially not after I discovered that Winchester Power Points game me the same terminal performance at a much cheaper price. And the Power Points also shoot around 1" @ 50M out of my 10/22 STD barrel (again, 10 shots).
