Query: Poor Quality Nails for the Porter-Cable Finish Nailer

These nails are not of the quality necessary for the Porter-Cable Finish Nailer that they are typically advertised with (FN250A). They sometimes came out 2 at a time, not at all, or caused the nailer to jam. I called Porter-Cable, and acquired their nails, and the problems went away. I would not recommend these nails, especially for this nailer.
