Re: 22 rimfie case failure??
Looks like the chamber might have been relieved of its 'dry firing burr' a little too far..
It takes 43 muscles to frown, 17 to smile, and 3 for proper trigger squeeze.
The latest caliber or gear is no substitute for experience and skill. Rifles and cartridges don't make hits -- shooters do.
Fact of life:
After Monday and Tuesday, even the calendar says WTF!
