I want this doujin very, very much!

Why do those cartridges read "quik stripper"?

Double discipline is nice, though.

This is probably the first time I'm seeing 12 gauge rounds on what appears to be strippers similar to the bolt action rifle versions. ME LIKE.

Those quick strippers for shells are used often in competition. One can quickly grab all four shells and load them. It takes skill and practice, though, which is why they haven't been adopted en masse by the tactical shooters.
