Cut them square,fewer cuts no scrap and the square edge helps line them up.nice hitahtci gun.also pop a line,and also nail on the tar line.two nails per cap.
You are cutting way to much off of each side of the caps. A 1/4" is more than enough. The reason that manufacturers make pre-made caps is so that there are 4 nails in each cap. And you don't cut the outside factory edge. The way your installing each cap is only getting 2 nails.
