Last weekend at the Michigan Campfire Shoot, my 375 Ruger Alaskan killed it's second scope.
It was a mid 90's Leupold Vari-X III 1.5-5 x 20.
The other was a Leupold VX-1 2-7 x 33.
Granted, both of those scopes had spent time on a 416 Rigby, a Remington 700 Classic 35 Whelen, a Mossberg 835 slug barrel, and last before this was an Ithaca M37 w/Hastings rifled slug barrel.
Can't say any of those was a cushy ride, but I'd like to find a tougher scope to put on the 375.
