Here's my follow up to this thread that I started. I've gone through most of the original carton. consistent with others' experience, I got significant leading. Just as an experiment, I then hand lubed a batch with SPG, and another with liquid alox. That cut down the leading significantly. I haven't had many failures to fire, and I can't speak to accuracy because I've fired them only in a Ruger SR22. I wouldn't think of shooting them through a decent rifle barrel.
Bottom line: They're a major PITA, but can be made to work. I'd have to be pretty desperate to buy more.
