I have never had an extraction problem with the case, despite the large number of shots.
I still shoot a tip up gun (Blaser K 95) in .308, never a problem and the shots from it, I can not count any more.
All this with rimless cartridges.
Here a pic from the weekend at the range.
My Ferlach double, o/u .458 480 gn Degol bullets.
Good or not ?
at 100 m .
Red dot sight(Burris fastfire) ,shot on the table.
