" You aren't operating the bolt on a Mauser or a Winchester ". This is another way of saying, "you aren't operating the bolt on a rifle on which the extractor cam is located in the right place". If the rifle is made so the camming service contacts the receiver before the sear hits the cocking piece, the rifle is less likely to fire when the bolt is slammed shut, extraction is better, and, of course, the rifle will cock on opening. If Remington claims it was designed this way, this is company-speak for " we like to build these things to sloppy tolerances but it will be just fine if you get used to it and expect less." GD
