Good point on the lever being able to load all the 22 ammo.
One detail I forgot about.
One thing you'll find with the BL tube magazine, the insert rod doesn't need
to be aligned with a notch.
Just push it in and hear it click.
The beauty is two fold.
You can spin it when it's in the loaded phase, makes for easier release.
Caution, as the lever is a surprisingly short toss.
Good choice.
