I'm planning to get a pneumatic framing nailer. I will be using mainly 8d & 16d nails for framing and sheeting. What brand/type is the most commonly used by pros? I got an bostich from 20 years ago and found that I couldn't find nail for it. What's the difference between full-round head, clip head and various degrees of nail types? I want to be able to use the most commonly used cheap nails sold at home depot or lowes. I don't want to stuck with a specific brand/type of nail only available by the nailer manufacturer. Is there such thing? Thanks for you help.
