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.
When placing a trail camera don't just look for a well used trail. What you want to do is look for a freshly used trail off by itself that goes from a north facing ridge, thick forest, brushy knob or some other similar bedding area to a food source. Don't forget water sources. Especially in the summer months the deer need water so look for a good trail going down too a creek surrounded by thick cover and place the camera 100 yards up from the water source.
Scent control is very important...
