Yes I had a hang fire once shooting Winchester silvertips through my model 66.
It was an old partial box of ammo that iirc came from a garage sale.
CLICK ....1001....1002....BOOM
Be careful with old ammo.
Stuff happens.

The next round was a squib that wedged in the forcing cone and locked up the cylinder.
I had to drive the bullet back into the cylinder with a wood dowel to open it.

The rest of that ammo ended up in the creek.
