Remington 710

[Dutchboy]

The bolt is light because it locks in the barrel, not the action. Everything else is just holding things together. Not necessarily inherently unsafe (the new BLR's for example, have the same design of the bolt locking in the barrel). However, when things let loose, the bolt isn't held by the action while the barrel splits: it lets go the moment the barrel gives up. Less than ideal if your face happens to be behind it. In the BLR, the rear of the action would catch the bolt (hopefully). FWIW, Dutch.
