Surprised. The recoil does seem all that different. Now the SL with a 4x weighs a bit less than the BLR with a 3x9, but still...... The BLR was a tackdriver with cheapo Wal Mart Federal 150's. I stopped after 1 box because I did not think that I could do better. Still working on the SL. Seems to shoot different every time. Might rescope it.
