Thank goodness nobody was hurt and your rifle was not damaged!

Prior to going to my range or hunting, I always go through a weapons prep at home that includes:
1) Cleaning of the bore to remove any storage lubricants.
2)Anti-sieze lube and installation of a ventliner, nipple or breech plug depending on the rifle.
3) General inspection of the lock or firing mechanism.

Best,
