Well, I've drunk the coolaid and purchased some CCW 4 shell competition shell holders. Now, in order to practice the multiple shells in hand, weak hand load, safely (without loading live shells repeatedly) I'd like some inert training 12g shotgun shells. I know there are some companies that sell them, but I've also heard/read that anyone who loads 12g shotgun shells can put together inert shells for such training. This may be a cheaper alternative. Gonna need at least 8.
