I found this load on the NRA website. They are using Ballistic Products HCW12 wad.
Now, I know with plastic wads you shouldn't substitute but what about fiber-wads?
Most of my shotgun shooting is currently on steel popper targets. The bays at the range all have piles of plastic wads in them. I find that is kinda-like littering. I am also cheap and I have several bags of Circle Fly fiber-wads. Do you folks think that would be a usable substitute? Would a nitro card help or hinder the load?
