Thanks. The rifle in question is a Rem. 700 ADL syn. in 30-06 with a Simmons 44 Mag 3-9x40 scope. The load used was a 150 gr. Win. PowerPoint over 57gr. of IMR-4350.
To a much greater extent than most mechanical devices, firearms are terribly unforgiving of any overconfidence, complacency or negligence.
