I have the Remington BDL LH(left hand) in the 270 calibre. It is as fine a rifle as your going to find or I wouldn't been using it since 1979.
As ChesterGolf said: the difference between ADL &BDL is strickly cosmetic.
Well mostly cosmetic. The ADL doesn't have a detachable hinged floorplate. Cartridges are inserted thru the action opening on the ADL but can be inserted thru the floorplate on the BDL. Cartridges in the BDL drop out the bottom to unload but on the ADL come out the action. The BDL also has two action screws but the ADL has a third thru the front of the trigger guard that holds on the trigger guard. That screw tightened to much can change point of impact. Other than that the actions are the same.
Hunting can be slow and frustrating if Mother Nature throws a warm hunting season at you. But things can take a drastic turn for the better with the onset of a cold snap. Whether you get snow or just a good, prolonged cold front, the hunting can improve on a dime. But cold whether can also make certain parts of the hunt more tedious. Here are some things to keep in mind when your prayers for cold weather finally pay off.
You can see a your quarry's breath when it is cold outside...
