thanks for the shotshell feedback. being in stock for a while, I know there had to be a reason nobody were grabbing these. and thanks to this excellent forum, understood Velocity and to look for warning such as primer-only, no powder, quiet, etc. but this particular product had no description or warnings.

PS: 12-GA ammo was easy to get but now starting to sell out (its much more expensive than 22LR, about $1 in box or 80 cents case quantities)
