Good questions Japle...
From the comments under the vid:
my buddy just got himself a little North American Arms 22 magnum and is taking a few shots. this little gun can be difficult to aim with. For self defense In high stress situations, it needs to be really close for a sure shot.
NOTE: the ammo used in this video is really old and might have been rained on out in his shed, No FTF (failure to fire)'s with new, name brand ammo.
UPDATE::::::: My friend in this video has done some more practicing and he can shoot his AA much better now::::::::::::::
My initial post was not meant to besmirch the gun(s), just that I had seen this only yesterday and it was still in my memory banks...
