Re: Rifle Explosion
He would have heard more than just a "click" on that second round if the primer sent a bullet into the rifling. If anyone ever pulls a trigger and hears less than the typical report of the rifle but more than just a click, best pay close attention to the ejected hull.
I realize that in the excitment of the hunt, we cannot all remember to examine such details, however, that is still the advice I recommend.
Hopefully, it will never happen again.
