I was waiting for someone to chime in with Bostitch, I used them about 12 years ago and they were at least 10 years old then. They were 1/2" crown though. Seems to me they were a heavier gauge staple than the 7/16" PC too.
What's up Hugeass?
I have a Porter Cable that has been trouble free for several years. I'd guess I've probably run at least 150,000 staples through it.:thumbsup:
