Years ago, I reloaded my Glock 22[b] several thousand times without a problem.[/b]
I did notice the stock barrel REALLY leads up, even worse than the .357magnum.
I switched to jacketed bullets because I got tired of scrubbing lead.
It wasn't till later, when I got on the web, that I heard about the KABOOM stuff. I've seen blown-up guns before, and even though the owner won't want to admit it, it's almost always a bad handload.
Except for on the internet, I've never heard anything bad about the .40 glocks.
We have a range that rents guns locally. I asked them once if they ever had a Glock KABOOM. They said the Glcoks were about the only guns they [b] didn't[/b] have problems with eventually.
