I have been shooting these nails in my Porter Cable Bammer for a few years now and I haven't had any problems.  Though I don't use my tools for a living, I am an avid woodworker and home renovator. As such I would say that in the past 5 years I have shot a thousand or so of these nails through my P-C Bammer gun and I can count the times it misfired on one hand. As long as the gun is set properly you should have no problems with jamming or with setting these nails below the surface of the wood.
