Went to two big hardware box stores just to check out PVC for fun as lots of folks are using it and thought I might make a Nerf gun using it, and to my surprise the ID is .600 or a little bit more ??? I thought 1/2 Inch scd 40 was supposed to be right around 1/2 inch. It was the same size at both stores ?
Am I looking at the wrong stuff, it says scd 40 1/2 inch on the pipe ?
