At least you acknowledge and shoulder the blame!
EVERY YEAR, someone comes in one of the stores fighting mad because the new rifle they bought missed. When we explain that they do not some in sighted in we get a dumb blank look...
I have one guy so mad at me because "I" had talked him into a Browning auto in 308 and he loaded it with 30/30 ammo. I asked him what happened to the box of ammo I GAVE HIM? He was "saving" it. He too never sighted it in.
Get to the range and back out there!! Good luck,
