G'Day Fella's,

Utah Shotgunner, please don't take this as criticism but it has already been wrecked, I can't see the point in destroying it.

It could still be used for what it was intended for, as a physical example for Show and Tell (but only with Dummy ammo!), for how these things Load (the magazine), Feed, go into Battery, Fire, Unload and Eject ammo/fired cases.
Maybe you could donate it to your local Gun/Hunting Club, for this purpose?

I recently milled out the chamber area and then another area, a few inches down the barrel, of a shot out .30 cal barrel.
This was just to show visiting inexperienced shooters (primarily), how the cartridge (a Dummy one) fits in the chamber, and how to adjust bullet seating depth, etc.

Regards
Homer
