No, the cams are different. The BT Mag has the BTX cam with the 3 different draw settings and the micro sync dial.I have a Boss and it is smooth. I actually shoot it in the #1 setting to get some speed. I'm a short draw @ 27". This bow is quite and dead on the shot. Cant' speak for the BT-mag? I believe they have the same cams? The IBO is faster on the BT-Mag as well.
