Do not attempt to fire that brass. The risk of case head failure is high.
Also.
Do not attempt to run that rifle with a hose clamp repair to the stock.
It will not shoot to regulation with a broken stock, or any stock that is not completely sound.

This post shows a photo of the rifle.
The wrist shows a line, although out of focus, right at the place where later in the thread you show the stock broken.

It appears that the repair was likely obvious.

In this thread from elsewhere in year 2012 you show photos of the rifle, without a broken wrist, and with no signs of a repair. You also state that the barrels are fully rifled.

When were those barrels bored from 'fully rifled' to the current state of what appears to be a rifled-choke-bored ball/shot configuration?
Who did that work?
Was the rifle re-proofed?

Who did the previous repair to that stock?

Something isn't right here.

Step back.
Seriously reconsider the path that you're following and think on a fresh new direction.

Cheers
