Oh,.....FWIW, I borescoped Ron Calderone's beat up early model old Browning BPCR at THIRTEEN THOUSAND rounds,.....just after he shot that "Grand Slam". Used a hawkeye with a digital doubler, on a TV screen, e.g. 27 1/2 power.

.....NO circumfrential marks were visible, and the longitudinal marks were AWFUL, compared to those visible in a new Badger.
This was part of a "Tune up",....and the old gun went back to work.

With a good spotter (Dave Maurer ringing any bells ?) , Ron could hit ANYTHING he pointed that thing at.

What you see is not always what you get, and what you HEAR (or read) is not always RIGHT.

'bout all I have to say, at this point.
