Like they said. It's a fixed internal magazine where the bottom floor plate opens out like a small door. So, imagine the floor plate of a detachable magazine except that floor plate has a hinge at the front end where the plate opens out, but the magazine does not detatch, the magazine spring and follower are also attatched to that floor plate. On the 700 BDL the floorplate release is a flush square button in the trigger guard just forward of the top of the trigger.
A word of advise with that 700 BDL. Don't allow the bolt to slam forward on it's own. It will easily do that when the action is open and the rifle is pointed muzzle down. Also the 700 BDL will need to be fitted with a much better aftermarket rubber recoil butt pad. Consider a Pachmayr butt stock recoil pad. For some odd reason Remington has found it cheaper for them to put a basic hard plastic butt plate on that gun, and those tend to really make shooting it (in a caliber like .30-06) very uncomfortable. Hope this helps.
Jim Zumbo, Craig Boddington, Ron Spomer and Wayne Van Zwoll are all solid contributers to the modern hunting literature. Through their gifts (both hunting and writing) they make us better hunters. Whether it is letting us learn from their mistakes or by teaching us new techniques,they help us harvest more game. But I suggest looking to the oldies, the fathers of the outdoor writing craft, to learn tricks that you might have not used.
I chose to shoot the 270 winchester because I grew up...
