So, I do basic DIY projects and have been doing it for some 20 years, but strictly do it as a recreational hobby. I have never attempted a project like the one I'm about to. I found out the wife is pregnant, and now have to build one to two bedrooms in the basement for family and friends to stay in. I live in Denver, CO and are required because of our clay soil to build a floating wall frame. My question comes down to I mostly have Dewalt 20v tools, and I have a 15 gallon air compressor that goes to 210 psi. Does the degree of the framing nail gun matter? What would be the best for this project and why are there different degrees on the gun?? Seems trivial, but I like to buy things once and use them till they are over worked. I am going to pre-assemble on the ground, then nail it in to the rafters. No judging, just want to know before I attempt this for the first time!! Thanks in advance.!!
