I recently acquired a number of 16g gas seals from BPI on the chance they could be forced into a 20g Mag tec brass shell, and as it turns out they go in with only a bit of effort. So, I was wondering if any of you have tried 16 plastic wads in 20g brass shells? I was thinking it might speed up reloading a bit and produce a better pattern if I didn't have to use fiber wads. Let me know your thoughts.
